In the current modern office and business environment, the audio-visual integrated system has gone far beyond the mere stacking of equipment. It has become a set of solutions that deeply integrate audio and video, display, control and network technology. The purpose is to create an efficient, collaborative and immersive audio-visual experience. From video conferencing by multinational companies to immersive exhibitions in museums, its core value lies in using technology integration to solve the pain points in actual communication and information transmission.

Why do enterprises need professional audio-visual integration solutions?

When many companies are in their early stages, they choose to purchase equipment such as projectors and speakers on their own. However, they often face technical problems such as incompatible equipment, complicated operating procedures, and sudden interruptions in meetings. A professional audio-visual integration solution will initially carry out requirements analysis and scene planning related work to ensure that all hardware and software can achieve seamless collaboration. For example, there is a conference room that integrates elements such as high-definition cameras, omnidirectional microphones, codecs, and large-size displays. This can make remote meetings feel like face-to-face communication, thus greatly improving the efficiency of decision-making.

The deeper value lies in unified management and control. An excellent integrated system can use a simple touch screen or mobile application to start the conference mode with one click, automatically adjusting the lights, lowering the curtain, turning on the equipment, and switching signals. In this way, the panic of non-technical personnel during operation is avoided, and the interference of technical complexity on users is reduced to a minimum, allowing the team to focus more on the content of the meeting itself.

How to plan a conference room audio-visual system to avoid common pitfalls

At the beginning of planning, it is important to clearly understand what the main purpose of the conference room is. Is it mainly used for internal training, presentations to customers, or high-frequency cross-border video conferences? Different scenarios have completely different requirements for audio collection range, display clarity, and network stability. A common mistake that often occurs is to blindly pursue high-parameter equipment, but ignore basic engineering such as room acoustics processing, screen viewing angles, and wiring redundancy, which ultimately greatly reduces the later effects.

Another key point is scalability reservation. People and business models in the enterprise may change rapidly. The system should have the ability to support flexible addition of equipment or function upgrades. For example, pre-burying a sufficient number of cable ducts that meet the specification requirements and selecting a central control host that supports common standard protocols instead of choosing a closed private system. In this way, if there is a need to increase wireless screen projection or integrated AR demonstration in the future, smooth upgrades can be achieved and the initial investment can be protected.

How to choose core equipment for video conferencing systems

In video conferencing, the selection of core equipment directly determines the baseline of the experience. In terms of cameras, you should choose products that have wide-angle lenses, automatic framing and speaker tracking functions to ensure that no matter what the sitting posture of the participants is, they can get a clear picture. If faced with a large conference room, it may be necessary to link multiple cameras to achieve intelligent switching between panorama and close-up.

The top priority is the audio equipment. Far more important than high-definition picture quality is clear speech. Array microphones with echo cancellation and noise suppression functions should be deployed. Voices from all locations must be clearly captured. The display equipment must calculate the appropriate size and resolution based on the size of the room and the distance between participants to avoid pixelated visuals in the front row and unclear text in the back row. Professional integrators can provide accurate solutions through simulation calculations.

How to match the sound system to different spatial acoustic environments

There are no two spaces. Their acoustic characteristics are exactly the same. Glass-walled conference rooms, carpeted training rooms, and high-ceilinged halls have different reverberation times, different standing waves, and different reflection surfaces. The sound system design must carry out professional sound field simulation and measurement, rather than just installing a few speakers. Improper matching will cause the sound to be muddy, reduce clarity, or have auditory blind spots.

"Systematic design" is the solution. During this process, ceiling speakers or directional speakers will be arranged in a distributed manner, and then cooperate with the digital audio processor to carry out partition management and frequency equalization operations. For example, in each exhibition area of ​​the exhibition hall, independent audio zones are set and arranged one by one, and different contents are played to achieve the effect of not interfering with each other. The processor can automatically process and correct the sound field defects in the room to compensate for the lack of frequencies caused by the building structure, so as to achieve the goal of allowing every seat arranged to hear balanced and fidelity of such sounds.

Can a central control system really simplify the operation process?

The value of the central control system is reflected in the reduction of complexity, but its design must be based on the actual operating logic of the user. There is a complex control interface that, even if it is very powerful, can hardly be called a success. A well-designed control system interface should have graphics and text descriptions, with a clear and clear hierarchy. Frequently occurring operations such as "turn on projection" and "join a meeting" should be placed on the homepage to achieve direct access with one click.

With such system stability and response speed, this is another lifeline. It must communicate stably with various third-party devices, such as air conditioners, electric curtains, and matrix switchers. With the help of programming, complex scene linkage can be achieved, such as when there is a "lecture mode". Automatically dim the lights, lower the projection screen, turn on the podium microphone, and turn down the volume of background music. It is this seamless experience that can effectively hide the technology behind the scenes, allowing users to focus on the front desk, and provide global procurement services for low-voltage intelligent products!

What should you pay attention to in the subsequent maintenance of audio and video integration projects?

Project acceptance and delivery is not the end point. Continuous maintenance is required to ensure the long-term stable operation of the system. It is necessary to establish clear equipment files and wiring diagrams so that faults can be quickly located. It is necessary to sign a maintenance agreement with the integration service provider and agree on the content of regular inspections. This content covers checking the device firmware update status, whether the cable connector is loose, the dust condition of the cooling fan, etc., so as to prevent problems before they occur.

At the same time, continuous operational training needs to be carried out for users. The turnover of personnel may lead to gaps in operational knowledge. Regular training can help ensure that new employees can use the system proficiently. In addition, keep the system expansion drawings and interface documents so that when the company needs to transform or expand in the future, it can have content to rely on to prevent blind construction from causing damage to the original system.
