Interviews and warnings, the two systems that were originally operated by each other, have evoked a trend of “integrating into one” in recent years. What are the reasons? What are the advantages and disadvantages between integration or independence? How to choose?
Video Intercom and alarm systems used to be two completely independent systems in the past, even in most of the world's markets. However, in the Asian market, China and South Korea have a strong market demand for the functional integration of video intercom and alert systems. However, in Singapore and other Asian markets, construction companies and system integrators still prefer to separate the
Video Intercom System from the alarm system and use it separately. Therefore, although in some Asian markets, the integration of visual intercom and alert systems has become a trend, but from the perspective of the global market, the integration between the two has apparently not yet become mainstream.
The stability after integration remains to be tested in the Chinese market. Although most video
Intercom System manufacturers have introduced walkie-talkies with integrated alarm functions, from a technical point of view, we believe that manufacturers should still make smart home terminals and video intercoms. The two different areas of the system operate independently. In fact, in order to ensure the stability of the system, it is believed that most of the contractors and system integrators still recommend that the video intercom system and the alarm system be operated independently. If the alarm is installed directly on a networked building intercom system, it may cause signal collisions and blockage of signals. It may also cause the emergency alarm signal to be delayed, which is not conducive to the stable operation of the two systems. The current mainstream alarm system networking is as follows:
Telephone Line Networking: The telephone line network is arguably the most robust network system. Through the telephone line network, alarm network can be realized. This is the most convenient method for the citywide network; but for a community, using the telephone line network to implement alarms is not appropriate.
First, the use of a telephone line network to transmit alarm messages, while saving wiring costs, still requires additional telephone charges. Second, each alarm unit (home) needs to have an alarm host (at least one dedicated dialer). Moreover, since the entire telephone line network belongs to the public network, if an alarm signal is delayed due to a problem in the telephone network, the telecommunications bureau cannot be held responsible for this; in addition, the use of telephone lines to transmit information is slower. It may delay the timing of the alarm.
The use of video intercom network to transmit alarm signals: The feature is no additional cabling, can save costs, construction is simple, a network and more. The disadvantage is that the signal is easy to block and delay the transmission of the alarm.
The deployment of a private network route and the transmission of an alert signal allow the alert system and the intercom system to operate independently. The advantage is that the system is customized, information transmission is not interfered by external factors, and it is both safe and can reduce the occurrence of signal blockage. The disadvantage is that the workload of laying the line is large, and the initial investment is high and the expansion is difficult.
Wireless network transmission: The use of radio wave transmission method to transmit signals, has strong anti-destruction, fast transmission speed and high accuracy, but the transmission range will be limited by the power of the transmitter. At the same time, if relays are used to transmit signals, once the receiver or transmitter fails, the interests of other users will be affected. At the same time, signal transmission is also affected by weather factors such as lightning and electricity.
The wireless transmission method is more suitable for the signal transmission between the front-end alarm sensor and the home user's alarm extension, which can effectively reduce the wiring cost of the renovated home. Although the alarm system and the video intercom system are independently or integratedly operated, each has its own advantages and disadvantages. However, considering the stability, safety, and effectiveness of the system, we do not agree to integrate alarms in video intercom systems. Features.
Reasons for the integration trend The main reasons for the integration of visual intercom and alert systems in the Chinese market are as follows:
To cater for the aesthetic needs of the builders: If the alarm system is installed separately from the video intercom system, there will be one more indoor unit, which is not beautiful enough.
Save on engineering costs: If a private network route is deployed to transmit alarm signals, the alarm and intercom systems will operate independently, increasing the wiring workload and the upfront investment costs.
Management method: In the European market, the alarm system is managed by professional alarm companies through the Global System for Mobile Communications (GSM), providing 24-hour service to end users, and instant networking with police stations, independent through community property management companies. Operation. However, in the Chinese market, the community alert system is jointly managed by property management companies in conjunction with intercom system operators. This is also the reason why the visual intercom system integrated alarm function in the Chinese market.
In response to market demand, customized products were launched. In response to market demand, some manufacturers introduced a series of walkie-talkies with integrated alert functions. Including replacing the past integration of the alarm function into a single interphone, and using two independent bus bars, the video intercom system does not occupy the channel of the home burglar alarm system. Judging from the mode of operation, this is actually two sets of independent systems in operation, but from the perspective of operational modes, users are still faced with a system that has both visual and intercom functions as well as alarm functions. This scheme considers the different needs of tenants, builders and system integrators.
Residents can have a humane and easy to operate system; system integrators can provide a stable and easy to install, wiring, system debugging and programming is also very convenient system solutions; builders can provide residents with a set of integrated alarm functions Intercom system. In addition, because the system operates through two separate buses (one for the video intercom busbar and the other for the alarm bus), it also ensures the stability of the system and the timeliness of the alarm response.
