In the field of home safety protection, many friends will ask questions such as how to choose and how to use glass shatter sensors, which are the headaches. After all, who doesn’t have window glass yet, right? Glass Break is a small thing that can monitor the sound or vibration of glass when it breaks and then issue an alarm in time. It is also a very important part of our daily security configuration.
The basic working principle of Glass Break is actually not complicated. Simply put, it is to "listen" or "feel" the special sounds and vibration frequency generated when the glass breaks through various small parts inside, such as microphones, vibration sensing chips, etc. However, different types of sensors may be a little different in their sensing methods
1. Sound sensing type : This type of sensor mainly works by "listening to sound". It can capture high-frequency sound waves emitted by the moment the glass breaks; but be careful that if there is always particularly sharp noise in the surrounding environment, such as a child screaming, it may accidentally trigger it to alarm, causing a false alarm.
2. Vibration sensing type : Vibration sensing type, as the name implies, will trigger an alarm when it feels vibration of the glass; generally speaking, it must be close to the surface of the glass when installed, so that the vibration signal can be captured more sensitively, otherwise it may not be easy to be used if the distance is too far.
3. Sound vibration compound type : This combines the advantages of the previous two, which not only listens to the sound but also feels shocking. Relatively speaking, the false alarm rate will be lower, but the price may also be a little more expensive.
When installing Glass Break, there are a few tips to pay special attention to. Otherwise, it may not work if installed, so it will be useless.
If the installation height is as high as possible, it will be more appropriate to install it between 1.5 meters and 2.5 meters away from the glass; if it is too short, it may be easily blocked by things, and if it is too high, the sensing range will not be so accurate.
The installation location is also a big question… It is best to face the direction of the glass, and not be blocked by heavy curtains, bookcases, and other big guys.
Also, if there is a lot of glass in the same room, it is best to arrange the number of sensors reasonably according to the size and quantity of glass to ensure that each glass area can be monitored, and do not leave any blind spots to provide global procurement services for weak current intelligent products!
Many friends may encounter some questions they don’t understand when using Glass Break. Here are some common ones!
Q: The sensor always calls the police on its own. What's going on?
Answer: This question may be that you install it in a place that will sway, such as when the window frame is loose, or there is continuous high decibel noise around it, such as when a high-power vacuum cleaner is working, it may cause it to falsely report! You can first check if the installation location is not correct, or adjust the sensitivity of the sensor to try it!
Q: Can sensors accurately sense glass of different thicknesses?
Answer: Generally speaking, most sensors can still sense ordinary single-layer glass, double-layer hollow glass, etc. for household use; but if it is a particularly thick or specially treated explosion-proof glass, you may need to choose a special model sensor with higher sensing sensitivity.
Finally, my personal opinion is that it is still necessary to install Glass Break at home, after all, it can add more protection to our home safety! When you make a choice, you can comprehensively consider the type, sensitivity, and price of the sensor according to the actual situation in your home, and choose the product that suits your home most! When installing, it is best to read the product manual carefully or ask a professional installation master to help with the installation, so that it can work better and protect the safety of our home.
