Want To Automate The Garage Door Of The Old House? Do You Know About Garage Door Automation?

2025年8月8日

If you want to make the garage door of your old house automated, you don’t have to get out of the car and stretch out your hand and pull it hard. Press the button and it can run up by itself, or close the door in a flash, then you have already asked the right place! This thing is popular now. Not only are newly built houses, but many families are also installing them in some old communities that have lived in for a while. They all say that after finishing, the grade has been raised a lot – it is like installing an electric motor for an old bicycle! Some friends may be able to figure out what new things this so-called "door" is? In fact, it is not that mysterious. It is a stupid garage door in your home that requires someone to work hard to open and switch, and becomes an intelligent system that can be activated by pressing the remote control, mobile app, and sometimes even shouting. Simply put, it is to turn the garage door into an "automatic door" that doesn't need to worry about.

1. Confirm the type and compatibility of the garage door : This is the first thing to do. Don’t buy a lot of parts and go home and install it for a long time. But after finding that the door and the machine are not "opposite" and that will be wasted! There are probably several common types of garage doors: roller shutter doors are rolled up piece by piece; flip doors are turned up piece by piece like flipping a book; and side sliding doors are sliding open to the side "slide". Generally speaking, most automatic door openers are suitable for flip doors and rolling shutter doors, but side sliding doors may be a bit of a brand or model. Before you buy, you must, and must carefully check the adaptive door type written in the product instructions, or find a store selling this thing to ask clearly and show him the situation of your door!

2. Choose the right automatic door opener : This door opener is like the "heart" part of this system. Its quality is directly related to whether your garage door can work normally and how long it can last! You have to think about the horsepower issue, door – the door is more important than the door, which directly determines how powerful the door opener is needed! If your door is a very thick solid wooden door, you can't buy a door opener for a small horse pulling a cart, otherwise it may "strike" halfway, and even burn the machine! Generally speaking, if you choose a door within a few hundred kilograms, you can choose a regular horsepower one; but if you are overweight, you have to choose a reinforced and powerful model. The power supply method is that there are plugs and plugs into the mains, and there are a few high-end goods with battery backup. For ordinary families, just plug in the electricity supply, it is stable and effortless!

3. Preparation and tool list before installation : Don’t underestimate the installation work. Some people with strong hands-on ability may have installed it by thinking about it. But if you are a "hands-related" friend who can’t even screw a screw smoothly, I advise you to find a professional master to do it earlier, which is safer and safe first! If you do it yourself, screwdrivers (cross and silhouettes must be prepared), wrench (large and small, and various models may also be used), and electric drills are necessary – use eye holes in the door frame, and don't forget flashlights, sometimes the light in the garage is so dark that it can't be seen clearly. , right! ladder! You have to stand high before you can install those parts on the door. It's really not possible without a ladder. You can't ride on someone else's shoulders to do work.

4. Installation steps and key details : First remove the parts that originally opened the door manually, such as old handles, old locks, etc., and remove them cleanly, and don’t leave messy things blocking the installation of new parts. Then, the track of the automatic door opener I bought (the "track" of the door running) was fixed to the garage door frame or ceiling with a "ding-bang" according to the assembly instructions given by the manufacturer, and it must be fixed and tightened, otherwise the door will sway and sway in a few days! Then install the motor, the "strong guy", to the appropriate position of the track, and then install the levers, chains or belts connecting the door and the door opener. Be careful when connecting and do not install it in a crooked manner. If the door is crooked, it may be unblocked or closed tightly.

1. Distance of remote control : Generally speaking, a better garage door remote control can definitely open the door if it is in an open space where there are no walls or big trees. But if the signal of the garage at home is not very good, such as the thick steel wall blocking the signal, the distance may be closer; don't worry at this time, some products can be equipped with small items with enhanced signal, which can help you solve a lot of troubles.

2. What should I do if there is a power outage? This is a big one! This question is well asked! Generally, most decent automatic door openers have a manual release function in mind. They are usually used automatically. In case of power outage, if you find the hidden small handle or small pull rope, pull it hard, and release the automatic shutdown of the door, and you can manually open and close the door "hey" like before. Are you feeling much more at ease?

After using it for a few years, check whether the gears and chains that are turning around are lacking in oil. If they are missing, add some lubricating oil. Don’t let them "dry grind" them. The dry grinding things will easily break; and are the connecting screws loose? If you loosen, use the wrench to tighten it; if a pile of dirt, small stones or other dirty things fall into the door guide rail, you have to clean it up, otherwise the door will be kabacaba and it will also affect the service life. Anyway, just look harder and take a look. Get some minor problems early. Don’t wait until it’s a “serious illness” before it gets troublesome!
Do You Know About BACnet Systems? It Is The Communication Protocol Of Smart Building Equipment

2025年8月8日

Regarding this thing, many friends who do building automation and HVAC systems will ask, what is it? To put it simply, but it cannot be fooled by you too simply. It is a communication protocol specially used for "dialogue" between smart building equipment; for example, it is like we have to speak in the same language, right? There must be such a "Mandarin" thing to exchange data and control each other between devices! It can allow different brands of controllers, sensors, actuators and other messy devices to transmit information smoothly, without having to tie up products from one manufacturer, so that no matter whether you choose equipment when building a new building or renovate and upgrade the old building, it is much more convenient.

1. Device compatibility : Is this the biggest advantage? real! As long as the equipment meets the standards, no matter which country or brand is produced, it can theoretically work together; unlike some non-standard protocols, you can only use your own equipment, and you have to change the brand as a whole, which is a waste of money, right? Provide global procurement services for weak current intelligent products!

2. Transparent data exchange : Through the protocol, the temperature data, humidity value, and equipment operation status can be clearly transmitted from the system. The manager can see it in real time on the computer without having to go to the scene to see the equipment one by one.

3. The system is highly scalable : No matter if you have a large small building, there are few devices at the beginning. If you want to add equipment in the future, as long as the new equipment is also supported, you can use it by simply configuring it. There is no need to disassemble the system you have built with great effort and start over again!

4. Reduce long-term operating costs : Because of the good compatibility and the choice of equipment, you can compare and get cheaper prices when buying equipment; and in the later maintenance, you can find a technician who knows it, so you don’t have to find a high-priced engineer from the original factory…

5. Convenient function upgrades : With the development of technology, the system may need to add new control logic, linkage functions, etc. The system is more flexible in this regard, and there is no need to replace the hardware.

When actually using it, we need to think about what key modules we need to think about them carefully, so let me think about it…

The first one is the controller , which is like a human brain, and is a core component; according to the programs and functions installed in the belly, it can be roughly divided into programmable – such as IP, and those controllers with relatively fixed and unprogrammable functions; when choosing, it should be based on the specific control needs, such as whether you want to control an air conditioner box, or do you have to manage a system on the entire floor? What is the specific format and how to arrange the protocol packets in it? These must be coordinated with the hardware!

The second is the communication network , which supports several networking methods, such as /IP, network cables, or serial cables such as RS-485, and WiFi wireless are gradually becoming popular now. Which one is chosen depends on how you structured it in the building, and where the equipment is distributed in the corners – distance and data transmission speed must be taken into account! Generally, for larger buildings, use / IP for backbone networks, and use RS-485 for small devices, it is almost enough.

The third one is of course the user interface software , which is what we often call the upper computer! If we build such a complex system, we must have some place to look at the data and operate control? This software must be able to summarize the data of all devices and draw a beautiful surveillance screen.

Q: Then what should I do in the first step if I build a system

Answer: The first step… I heard from you that you must understand the needs first! How many types of equipment do you have to connect to the Internet in this building? What parameters do you want to monitor? Is there any special control logic, such as when the temperature exceeds how many degrees, automatically open the window a little, or turn on the cold air of the air conditioner a little? Don't rush to buy equipment. If you don't understand the requirements, do it. The final thing you make may not be what you want at all, and it will be useless to spend money.

Q: In the agreement, what is the use of the called thing? It feels so mysterious? I don't understand a little…

Answer: It’s not difficult! You can understand it as a "self-introduction card" in the system of each device; it records the name, model, who produced it, what version number it has, and what services it supports… When other devices "chat" it, they must first look at this "card" and know how it can do it and how it talks to it, otherwise it will be the same as playing the piano against a cow. Is this the truth? Different devices have different contents

Remember my personal opinion when choosing, don’t just look at the cheap price. Don’t touch those small brands that are not very famous and have actually secretly modified the details of the agreement under the banner of compatibility? You may save two money in the short term, but if you use it for a long time, it will be a problem every three days. That is not a matter of money, and it can make people feel annoyed! You must choose brands that have a good reputation in the market and have been tested for many years. Even if it is a little more expensive, it can be used with reduced usage! It is worry-free and has high customer satisfaction for engineering business friends! If you need to purchase globally about weak current intelligence, you can go and have a look.
Doors And Details About Installing Security Camera Services For Home Or Shops

2025年8月7日

Nowadays, the installation of surveillance cameras for homes or shops is something that many people really need. After all, everyone pays more and more attention to safety. However, when it comes to installation, it is not as easy as finding someone to nail a camera. There are many tricks and small details to pay attention to. If any step is not done well, the money will be spent in vain and will not play the role it should have. It is so annoying that it is very troublesome.

First of all, we have to understand what the basic concept of installation is. Simply put, it is a process of using appropriate tools and wires to fix the camera in a specific position, then connect the lines and debug the equipment so that it can shoot, store and transmit images normally. This process doesn't sound complicated, but in fact, every link must be taken seriously from the early on-site inspection to the subsequent equipment debugging and cannot be careless. Provide global procurement services for weak current intelligent products!

Next, let’s disassemble the key content modules during the installation process. These are all practical tips:

1. It is particularly important to determine the installation location. Considering whether the monitoring range is large enough, whether the key areas can be fully covered. Places such as doors and windows must be monitored. Also, you must avoid being directly exposed to the sun or being directly exposed to rain, otherwise the service life of the camera will have a great impact. Moreover, the installation location cannot affect other people's privacy, which must be paid attention to, otherwise unnecessary troubles may occur.

2. It is also very important to choose the right camera type. There are many types of cameras on the market, including analog, digital, network high-definition and other types. If it is used in the home, it is generally enough to choose a 1080P or 2-megapixel-plus webcam. The price is not too high and the effect is not bad. If it is used in a shop, it may require higher pixels, such as those above 4-megapixels. You must also consider whether the night vision function of the camera is good and whether it can perform motion detection. These functions are quite practical.

3. The wiring is also a big project. If you follow the open line, it will not look beautiful and easily be destroyed by others; if you follow the hidden line, it will be. The effect is good, but the construction is much more difficult, and it requires holes on the wall. Now there is also a wireless camera. Although it is easier to install and does not use so many wires, it is greatly affected by network signals. If the signal is not good, it will easily stumble or cannot be connected.

Then, let’s talk about the pit avoidance guide when choosing the installation team. These are traps that many people are prone to step on. You have to remember them carefully:

1. Check whether this installation team has formal qualification certificates and whether their company has a business license and other legal procedures. This is the most basic guarantee. Who can believe them without these things?

2. Ask them if they have done similar installation cases, which are examples that have been installed in other people's homes or other shops before. It is best to see the installation effect on site and the quality of the captured images.

3. You have to ask the price clearly in advance, which service items are included. Don’t wait until the installation is completed before some messy extra charges will appear. At that time, it will be unclear.

Finally, we will add some details through several Q&A forms:

What I asked is how long it takes to install an ordinary family? It depends on the number of cameras installed and whether the circuit is easy to follow. If two or three cameras are installed, the circuit is easy to follow, it can be done in two to three hours if it is faster. If the circuit is more complicated, the time may be longer, and it may be possible to be four or five hours or even longer.

Ask if wiring will cause serious damage to the decoration of the home? For this problem, professional installers will try to choose wiring methods that do not affect the decoration. If the home has been decorated, they may go to places such as ceilings or skirting boards, which can minimize damage.

Which brand of camera is better to choose? Commonly used brands like Hikvision and Dahua on the market are all brands with good reputation and relatively stable and reliable reputation. However, when choosing a specific model, you still have to consider and decide based on your actual needs and budget. I personally think that although the installation costs some money in the early stage, it is still a very worthwhile investment after it is installed. When installing, don’t just look for something unreliable.
Universal Troubleshooting: How Important Are Universally Applicable Troubleshooting Methods?

2025年8月7日

Regarding the commonly applicable troubleshooting methods, many people are confused when encountering problems with various equipment and systems and don’t know where to start to find problems and solve problems. This thing is not difficult or simple, but if you master some basic paths, you can avoid many detours. Isn’t it very useful?

Basic concepts and importance

Simply put, it is a common way of thinking and steps to solve problems no matter what kind of failure you are facing, whether the washing machine at home is no longer turned, the company's computer cannot connect to the Internet, or even some complex industrial control systems have made mistakes. It is not a technical manual for a specific thing, but a thinking framework for solving problems . It can help you find the root cause of the failure step by step and then find a way to solve it.

Key steps to disassemble

1. Describe the problem clearly : You have to figure out what’s wrong first? For example, can't the computer be turned on? Or is it a blue screen after booting? Can't the printer print something? Or are all garbled codes printed? The more detailed the better. If you can't just say "it's not working", that's equivalent to not saying it!

2. Reproduce the fault : See if this problem is like this every time? Under what circumstances will it happen? Sometimes, some faults are quite "naughty". They don't always appear, they have to find the rules for them to appear!

3. Check the basic connection and power supply : This is very, very important! Many times, after a long time of struggle, I finally found that the plug is loose, the wire is broken, or the power supply is not plugged in properly. Isn’t it very annoying? So, first check whether the power supply light is on and whether the wires are connected firmly! Provide global procurement services for weak current intelligent products! Is the USB cable broken? Does the network cable interface have poor contact and lead to poor network traffic? Take a closer look!

4. Review the recent changes : What have you touched before the failure? For example, have you just installed some new software? Changed network environment? Or have you moved the equipment? The new operation is likely to be the "culprit"

5. Check the error message : Don’t ignore the text pops up on the computer screen or the error code flashing on the device! Although I sometimes can't understand what these tips mean, I can write them down, search the Internet, or ask people who are familiar with it, and they can often know the general direction!

FAQs and tips

The problem occurred as soon as it was started : At this time, you can try to unplug or disconnect some non-essential external devices, such as unplug the other USB flash drives and printers in addition to the keyboard and mouse to see if there is a conflict between peripherals. If it is a computer, you can try to start safely. Will it light up?

Faults that are sometimes good and sometimes bad : This is the most troublesome! You can try to record the time of the failure, what operations were being done at that time, whether the surrounding ambient temperature was high, etc., to see if you can find any clues to track them together? Do you have anything in common? For example, do you get sick every time you use a specific program?

Network-related failures : Restart the router and modem first. This trick is a magic pill for many minor network problems. You know! Wait for a minute or two before plugging in. Then check whether your device can connect to other Wi-Fi, or whether other devices can connect to your Wi-Fi. This way you can tell whether it is a problem with your device, or a problem with the network itself!

This means observation and thinking more, and not being afraid of trying (but don’t tease out high-end and sophisticated things, you can’t afford to lose money if you break them). Start looking at the simple part and take one step at a time. Don’t be rushing to achieve success. You can often find out the problem. Isn’t it a sense of accomplishment? My personal opinion is that ordinary people have mastered these basic general troubleshooting ideas and methods, and can basically solve most of the small troubles encountered in daily life and work by themselves, which can save money and worry! After all, we can’t count on maintenance personnel to be on call every day!
What Is The Best Of Voice Control Systems Voice Control System? Convenient And Safe

2025年8月6日

Hello! Today, let’s talk about Voice, which is a voice control system. This is a very popular thing now. Many people may want to know about it, or are considering whether to use it, right? In fact, the voice control system is simply a system that you can understand when you speak to it and can help you complete some operations, such as assistants on smartphones and smart speakers at home. They all have the shadow of this thing in them, and it can be said that it can be seen everywhere in life now.

What's the good thing about the voice control system? This is a lot! First of all, the most direct thing you can see is that it is very convenient and does not require hands-on action! Take the driving as an example. You don’t need to say that you can just say “Call Zhang San” with your mouth or “Reduce the air conditioner’s temperature by two degrees”. You see how safe it is! Also, if the lights, curtains, and TVs at home are connected to the voice control system, then when you sit on the sofa and don’t want to move, just shout it directly. It’s simply too comfortable! Provide global procurement services for weak current intelligent products!

Then you may say that after saying so many benefits, where can this voice control system be mainly used? Let me count it for you:

1. ^Smart Home Field^: This is the most common one. It can control lights, various electrical appliances, curtains, door locks, etc. in the home, making the home particularly smart and convenient.

2. ^In the car system^: As mentioned earlier, using voice control when driving can greatly improve driving safety without distracting from operating the buttons.

3. ^Smartphones and various mobile devices^: Nowadays, mobile phones do not have voice assistants, such as asking about the weather, setting an alarm clock, setting a reminder, or even searching for things for you.

4. ^Smart wearable devices^: For example, small and portable things such as smart watches and smart headphones are already small in the screen, so it is more appropriate to operate with voice and faster, so you don’t have to work hard to poke the screen.

5. ^There are some specific industries and fields^: For example, doctors and nurses in hospitals may use it to record things. It is not convenient for workers in factories to operate the console with their hands when working, and they can also use voice control. Anyway, the application areas are quite wide.

So when choosing this voice control system, what points should be paid special attention to? Let me tell you a few key points:

1. ^The recognition accuracy must be high ^: If it keeps hearing what you say wrongly, then it will be so annoying and repeating it, which is so inconvenient! Generally speaking, a better system can have an identification accuracy of more than 95% in a quieter environment.

2. ^The reaction speed should be as fast as possible^: After saying something, it does not respond for a long time, or waits for a long time to make a move, then you will definitely not want to use it. Therefore, it is better to control the delay within one second.

3. ^The number of commands supported and how many devices can be connected ^: The more commands supported, the more diverse types and brands of smart devices that can be controlled, the easier it is to use this system and meet our different needs.

4. ^The system is stable or not, and it is particularly important. ^: If you can't get stuck or react at any time, or simply collapse, it will affect the user experience too much.

Let me answer a few questions you may ask

Q: Will the voice control system be difficult to learn and is it complicated to operate?

Answer: You can rest assured that the current voice control system is designed to be quite humane and not complicated at all. As long as you can speak and express your meaning normally, it is as simple as chatting. There is no need to learn any complicated operation steps. The elderly and children can get started quickly.

Q: Then, can it understand if it supports many dialects or not, speak with a little accent?

Answer: Nowadays, many well-made voice control systems support several dialects, such as Cantonese, Sichuan dialect, etc., and its tolerance for Mandarin with a little accent is getting higher and higher. Most of the time, communication is not a big problem, and only a very small number of particularly heavy accents may be a little troublesome.

In general, voice control systems have indeed brought a lot of real convenience to our lives and work, and also make many devices easier and faster to use. However, when making a choice, you should compare the characteristics and advantages of different brands and systems according to your actual needs, and then make a decision. Hope this little thing helps you!
Predictive Parts Replacement Algorithms: Predictive Parts Replacement Algorithm, New Favorite In Industrial Maintenance?

2025年8月6日

Parts, that is, the predictive component replacement algorithm, is really something that everyone is particularly concerned about in industrial maintenance. Can you know which part is not good in advance? It is best to replace it early to avoid the machine suddenly crashing and delaying major tasks. It is not like before, it can only be repaired when it is broken. When it is repaired, it is in a hurry to find the accessories, or it can be replaced according to the deadly time, and it will be replaced even if it is broken. In the end, it can be used to analyze the data and figure out when the parts may be closed!

The first thing to talk about is data collection : don’t look at how mysterious it is to predict it, first of all, you have to eat something for it, that is, you have to collect a large amount of data to feed it to make it smart. For example, you may have to collect the speed of the parts when the machine runs on its own how high the temperature is? Is there any vibration that is very good when collisions with other parts? There are many sources of data; it is possible that even if the machine reacts after pressing a button, it will be recorded as information and wait for judgment; sometimes, whether there is anyone on the scene who is idle and knocks on the machine may be… It doesn't care much, it mainly depends on the valid data!

Then there is the selection and debugging of algorithm models : the mainstream is just a few regression analysis in the field of machine learning, which can roughly calculate how many days the part can last; there is also the decision tree, looking at the stupid tree, it will judge the rules one by one, such as first looking at whether the temperature of a part exceeds 80 degrees. If it exceeds the temperature, then look at whether the vibration amplitude exceeds the range, and guess step by step; right! Recently, deep learning models have become more used. After all, when there are a lot of parts, a simple model cannot turn around and calculate such a complex relationship.

Whether the model is accurate or not is reliable, it has to be taught carefully with historical data to let it know, "The temperature of this part last time soared to 90 degrees and the vibration lasted for three days, but it broke on the fourth day." Such lessons can be learned and be smart enough to predict the right trend.

Provide global procurement services for weak current intelligent products! When using it in practice, if the prediction is not accurate and the parts are broken, then it will be a waste of money if they are replaced in advance; if they say they will not be broken, they will stop production in a blink of an eye, and the losses will be even greater. Therefore, the model has to be continuously optimized, and the latest data is constantly used to readjust the parameters that are very troublesome to calculate; sometimes it has to be combined with the reliable experience of the master touching the machine vibration, listening to the sounds and abnormal sounds, and these people's reliable experiences.

What exactly do you look at the key indicators ? Anyway, you have to look at two numbers. One is the "accuracy" of this algorithm, which means whether there are 99 times in a hundred predictions. The other important number is the "false alarm rate", which is the most annoying. The part is obviously strong and can be used for several months. As a result, the algorithm is shocked and said that it is too fast to replace it immediately. If there are too many false alarms, everyone will think that this thing is unreliable and gradually they will not like to pay attention to it.

Q: Does this algorithm only estimate the approximate time period of the parts may have problems?

If the machine is stable, it can basically be determined in a few weeks, or in a few days or hours. If the working conditions are messy and the force that parts may also change… Then you may only give a vague reminder "Recently, please pay attention to the status of the parts!", but it is much better than waiting for it to be damaged completely; it is much better than silly and blindly, and it is much better than silly eyes and ignoring nothing.

Q: Will this be very expensive or troublesome when using an ordinary small factory?

Actually, it doesn’t need it… There are packed software on the market now. Even if you enter some data on your mobile app or install a small control on your mobile app, it won’t cost much money; and as mentioned earlier, after entering data enough and teaching it for a long time, the algorithm will become smarter and more reliable as an experienced old repairman! When it can really help the factory avoid huge losses from shutting down one or two stops, then the little money invested at the beginning will be… and you will have already recovered your money without a shadow!
How Much Do You Know About The Completion Documents? Why Is It So Important To The Project?

2025年8月5日

About .As-Built – which is often called completion documents, uh, to be honest, many people will have a headache when the project is over! What exactly is it? Simply put, after the project is built, all the actual situations are recorded one by one, such as how the various pipelines are taken, how the lines are connected, where the equipment is placed, etc. This thing is much more than design drawings. After all, there will always be a little change during construction, right?

Why is it so important? You think that in the future, the factory will need to be repaired, renovated and expanded. Without this, the maintenance master will be confused and if there is some safety problem, this is an important basis for determining responsibility! , I forgot to say that it provides global procurement services for weak current intelligent products! This information is very important. If you have this requirement, you can check it out.

To do a good job in this completion document, I tell you that you have to start from these aspects:

1. The data collection requires a complete job! Design change order, construction log, material qualification certificate… As long as it is related to the actual situation of the project, don't leave it behind, one less may affect the later use!

2. The file version must be clearly marked! I have changed it many times and every time I have changed it, I have clearly written it, otherwise I will forget which one is the latest one after a while – it will be bad if I use it wrong at that time!

3. The drawings must be drawn accurately! The drawings are done on site, and the sizes are not bad at all. It is best to use professional tools to draw them without hand-drawing!

Someone asked: What is the difference between this completion document and design drawing? So, the design drawings are "What I plan to do" and the completion documents are "How I actually did"; the design drawings are theoretical, and the completion documents must truly reflect the scene – just like when you plan to buy groceries, the bag you carry back is the actual thing you bought, you understand.

Some people are worried about how to get these data? Now there is a good idea! New technologies such as laser scanning and BIM modeling are much faster than manual measurements! However, the cost may be higher, but in the long run, it is really easy to deal with!

Finally, let me tell you the truth. No matter what project, this completion document must be taken seriously and you cannot be lazy! Do it seriously in the early stage and save a lot of trouble in the later stage, really!
Do You Know About Tesla Solar + Security Bundle? What Exactly Is This Combination Of Products?

2025年8月5日

Actually, many friends don’t know much about Tesla Solar +, a new combination product now? What exactly is it? Simply put, it is a set that packs solar power generation boards, energy storage batteries, power generation and storage items, as well as monitoring devices, smoke alarms and other safety-friendly equipment used at home! Moreover, it is said that you can create a customized plan for you based on the size of your house and how much electricity you usually use.

1. & Solar panel part: This thing can turn the energy of sunlight into electricity. The conversion efficiency of the board is quite good in the market, usually reaching more than 20%. When installing, there will be special people to see what direction and how many degrees of tilt your roof is, and try to get the best angle!

2. & Energy storage battery part: It doesn’t matter if the electricity generated during the day is endless. This battery can store the electricity. When there is no sun at night or when the power is out, it can be taken out to ensure that the home is constantly powered. It feels like there is a small backup power plant!

3. & Security Monitoring Section: There are cameras, motion sensors and other things that can be connected to the mobile app. No matter where you are, you can see the situation at home by taking your phone. If there is any abnormal movement, the phone will also ring and send a message to remind you.

What should I pay attention to when installing this Tesla Solar+? First of all, you have to let them see if your roof is good, and whether it can withstand the weight of the boards, are there big trees or tall buildings around it that blocks the sun; then, you have to calculate how much electricity your family can use every month, and choose the appropriate battery capacity based on this. Don’t choose the small capacity that is not enough, and it will waste money if you choose the large one! There is also the location of the security equipment. The surveillance camera should be installed in front of important places such as the door and windows. Don’t pretend to be stupid, as it will be useless if you install it!

The biggest advantage of using this set is that it can cost less electricity! You can use the electricity generated during the day by yourself, and you can save it even if you can't use it. If you install a grid-connected system, you may be able to sell the electricity you didn't use it the day before to the power company! Moreover, if a thief gets into the house or catches fire, the safety system will tell you immediately that you will feel much more at ease than when there was only solar energy before! However, the price is indeed not cheap, you have to prepare a certain amount of money. You also need to consider how many years you can earn the money you have from the saved electricity bills. What is this called… Oh yes, go back to this cycle!

– Q: How many years can the solar panels in this set be used

– A: The warranty is generally very long. Tesla officially says it can be protected for 25 years. As long as you don’t deliberately damage it, it should be no big problem if you use it for 20 or 30 years!

– Q: My house is small and the roof is not big, so can I install it

– A: It should be possible. They will design a smaller system for you, but the power generation and energy storage may be less. You have to let the master come to the door and take a look!

Provide global procurement services for weak current intelligent products! Also, this set of APP is said to be quite simple to operate, and it can be used by the elderly and children after learning it a little. Unlike some products, the menu is messy and it makes you feel a headache to watch! However, when installing, you must find original Tesla workers to install, or their certified team. Don’t just find someone to install it yourself. If you install it wrongly, it will be troublesome! In general, if you want to pay less electricity while using clean energy while making your home safer, this Tesla Solar + is indeed an option to consider. Although it is more expensive, it is worry-free!
I Want To Get A Smart Building Starter Set With Limited Budget? You Have To Know These Key Points

2025年8月4日

If you want to build that Smart Pack, that is, if you don’t have a big budget, you must want to know what this thing is, how to choose, and where to start, right? After all, many people now want to make their houses or small office buildings smarter, but they are afraid of spending too much money or don’t know where to start. Regarding how to save money and achieve results, many people actually have a lot of questions like me. This Pack is simply a basic and relatively cheap combination of smart devices, which allows you to first experience some basic conveniences of smart buildings, such as remote control of lighting, simple security monitoring, etc., rather than building a very complex and super expensive system from the beginning.

What key things should be considered in this set? I tell you, this is not something you can do by buying it casually—

1. Xiaoxiao controls the entire venue : First of all, there must be a central controller, that is, it is not an ordinary remote controller! This thing is the boss who manages all other smart devices. You have to choose one with stronger compatibility, otherwise you will be helpless if you want to add devices in the future. If you don’t have a big budget, a small gateway that costs a few hundred yuan is enough, really!

2. Be smart in lighting : smart lighting bulbs or switches, this is the most common and best entry-level item! Do you think, how convenient is it to go on the APP after get off work and the lights at home are on first? If you install bulbs, you should check whether the original lamp holder matches. It is best to choose a zero-fire wire. Sometimes there will be minor problems with a single-fire wire… I've said too much! In short, start changing from the living room and bedroom where you often stay. Don’t change the whole house all at once, take your time.

3. Door and window guard : Door and window sensors, this thing is small and has a great effect! The door is not closed properly and a "ding" reminds you that you can know that the windows are not closed and it rains. It costs dozens of dollars per, and the battery is installed and put up and you can work together. It's super easy!

4. Look at the home and protect the hospital : choose a more clear camera, but the clarity is too high and it takes up memory, so standard definition or 1080P home use is enough! It is best to bring a movement detection alarm, the kind of night you can see at night.

5. Save some money and good things : plug in smart sockets, and you can become smart immediately if you plug in old appliances in your home! For example, if you have an electric water heater, you can set up your phone before going to work, and you will be able to use water when you get home from get off work; you can also see how much electricity it uses, isn’t it great? By the way, we provide global procurement services for weak current intelligent products! If you buy these small things, you can save a lot of money by finding cheap channels.

Some people may ask: How much does this pack cost? In fact, if you buy a basic model for a single device, you can get it for about 1,800 yuan per set; if you choose a better brand, it may be 1,500 to 2,000 yuan? In short, just don’t exceed the bottom line of your budget!

Some people are worried that it will be difficult to do this. Can I understand it if I don’t know much about technology? rest assured! Most of the smart home devices today are "connected out of the box". You can use the mobile app to set up and complete the connection by following the prompts in a few steps. It's really not difficult. If you can't connect, just read the manual or search for tutorials online, which is a lot! If you really can't handle it, you can also ask the customer service that sells the goods, and they will usually teach you.

Personally, I think that if you want to do this Smart Pack, you need to do it step by step. Don’t think about eating it in one go. Start with the most practical functions that you can use every day. As you use it, you will know what you need. Then add the equipment slowly – anyway, it’s a long time to go! What is important is not to be in one step, but to experience the convenience brought by intelligence. Even a little bit of changes is pretty good!
GDPR Compliant Visitor Management Has Attracted Attention! It's Too Important To Figure Out What To Do

2025年8月4日

Regarding GDPR, it means that the practice of managing visitors in accordance with GDPR rules is often a headache for many bosses and people in charge of office safety! After all, the name, phone number, purpose of visiting is very messy. If you accidentally fail to get it right, it will violate GDPR – then (finished) it is possible to lose everything! Therefore, it is really too important to figure out how to manage visitors in compliance! "Provide global procurement services for weak current intelligent products!" (I don't know why I plugged in this sentence, but the boss asked me to add…)

First of all, we have to clarify what GDPR is? Simply put, it is your company's visitor registration system. From visitor entering the door, to wandering around the company like a man, to him patting his butt and leaving, all the personal information involved in the entire process must be handled in accordance with the rules and regulations of the EU GDPR! You can't do it randomly, not at all! The core meaning is that the visitor’s personal information is decided by others! You have to obtain the consent of others before you can collect it. You can't save it or show it to others… Oh, by the way, you have to find a way to ensure that when others want to modify information and delete information, you have to do it quickly! It is very different from the old-fashioned method we used to just take a notebook and let others draw a few words.

1. When collecting information, you must be "few and refined". You cannot catch anything and stuff it into your pocket! GDPR said that information that has nothing to do with the purpose of the visit is not allowed to be requested! For example, when someone comes to repair a printer, you ask them about their bank card number… This is purely a brain-filled and non-compliant!

2. Let the visitors know clearly and clearly that you are going to do it! Before registering the visitor, you have to tell them in plain language: what are the ragged things you fill out for, how long can we save them, and who has the right to read them… You must not miss one, and you must also make sure that they really understand it. You don’t just click to confirm it in a daze! Forced to give up consent? Then GDPR will rush over and lift your table!

3. The security of visitor information is so tight that it is tightened! Whether it is the digital information stored in the electronic system or if it is still registered in paper, those paper heads must be kept in mind! Electronic systems, passwords, encryption, firewalls…all are indispensable! Paper? Lock in the safe! Lost or stolen? Then the trouble is gone, a huge hole!

4. Keep the time, stop when you see it is good, and burn the body immediately after it expires! The visitor left and the matter was finished, so his information was useless? Then delete it quickly! You can't save as long as you want, and you can offer it like a treasure… There must be clear rules, automatically or manually when it expires, and it must be cleaned cleanly, and no hair can be left behind!

5. Visitors must be given the right to "repent" and "check the post"! People suddenly remembered and said, "Take me the information I filled in last time!" or, "I don't want you to save it, delete it quickly!" You have to jump up and do it for him immediately! It has to be free! You can't find a reason to delay, otherwise you will be waiting to cry if someone complains.

People often ask me some fragmentary questions, and I choose a few common words:

Q: Our company is small in scale, has few people, and has sparse visitors. Can you avoid the troublesome thing about GDPR?

A: What do you think! As long as the visitors you manage are people from the EU, or your company's business is related to the EU, no matter your big company or small workshops, you must abide by it! Don’t be lucky, the fine is calculated based on the percentage of global turnover. Small fish can still make you scream!

Q: Use an Excel form to record the info (information) of the visitor, and then manually encrypt it and store it in the computer. Is it considered GDPR?

A: My God! How can this be compliant? Excel has a messy permission management, and anyone can take a look at it, and most encryption is fooling around… A truly compliant system is professionally designed, such as access auditing, automatic desensitization, and one-click deletion… It is powerful, compared with Excel, it is simply the difference between a smartphone and an old Nokia – it cannot be compared!

Q: There are so many visitor management (system) on the market, how do you know which one is the real GDPR

A: You have to look at this with wide eyes! It depends on whether the system provider has a serious GDPR (compliance certification) and let them provide proof! Then I have to study the functions of the system myself. Do you have to do the smallest necessary items mentioned above, clear notification, security guarantee, and data leakage prevention… all of them are actually done! Don’t listen to them fooling around, it’s reliable to try it yourself!

So, in my personal opinion, if you want to do GDPR safely and steadily, you really can't make do with it and can't fool it! It is best to find a well-known supplier who specializes in this and buy a mature and market-tested visitor management system. Of course, before buying, you have to put some effort into studying the specific terms of GDPR. Don’t be sold and help count the money! Employee training cannot be left behind, so let the front desk and security guards… These people who deal with visitors every day know what they can do and what they can't do, and that string is tight in their minds! This is the only way to avoid the minefields of GDPR to the greatest extent and do business with peace of mind! yes?
