Talking about the advantages of video intercom and its technical application

In recent years, building video intercom system has become an integral part of residential construction as part of building intelligence, playing an active role in the security of residential communities.

Visual intercom advantage analysis

1. The wiring is simple compared to the analog video intercom system transmitted by the dry bus system. The digital video intercom system is much more convenient in terms of wiring and installation and debugging. Because the digital video intercom system uses TCP/IP to transmit signals such as sound, data and image images, a network cable can solve all problems, greatly simplify the wiring project, and make the installation and debugging of the residential intercom system change. It is simple and the construction period is also greatly shortened.

2. Powerful networking When all signals are digitized, it is easy to meet the networking needs. Digital video intercom system indoor unit is like a small computer, both high-performance CPU, another DSP digital processing chip, making powerful data processing capabilities become powerful networking capabilities for other security sub-system integration to provide more More convenience.

3. Expandable IP networking has strong scalability. It can not only realize video intercom, but also realize multimedia information transmission, broadcasting, security alarm, smart home, IP videophone, VOD on demand, image monitoring and Value-added services and other functions.

If you access the Internet, you can configure, monitor, remotely upgrade, and remotely read any terminal (visual walkie-talkie) on the Internet. It can not only meet the traditional video intercom application, but also provide security alarm, smart home control and other functions, and become the core hub of the "digital home".

4, long transmission distance Now the community development scale is getting bigger and bigger, using image amplifiers and other solutions, can also extend the transmission distance to a few kilometers, but the cost is too high. The video intercom system based on TCP/IP has no distance limitation and can realize low-cost long-distance transmission.

5, low overall cost has always been a fixed concept in people's minds: "New technology means high prices, new products must be more expensive than traditional products." Then, as a leading digital intercom system, must be better than Is the traditional analog video intercom system costly and costly? In fact, from the point of view of installation, debugging and wiring, using TCP/IP transmission mode can reduce a small investment, shorten the construction period, save wire and labor costs, and easy maintenance. Therefore, digital visual pairing is adopted. Telling the system is more cost-effective.

Video intercom technology application

The building video intercom system generally includes a visual intercom type and a networked alarm intelligent type, which can meet the different needs of different occasions such as single households, villas, ordinary houses, high-rise buildings and social residential quarters.

1. Single ordinary intercom system

The system is suitable for high-rise, multi-storey buildings that require only intercom and electronically controlled unlocking and do not require networking. It consists of a door host, a user extension, an uninterruptible power supply, and an electronic lock. Adopting the bus structure, the main line is a three-core line, and the two-core non-polar line connection is transferred to the user through the interlayer distributor. The bus-to-user extension uses a layer-and-question distributor to isolate and protect the bus, so that any extension fault or short-circuit of the extension line does not affect the normal operation of the system, greatly improving the reliability and stability of the system. The user extension must be coded, the extension is universally interchangeable and convenient for after-sales service. The system also has direct call type and digital type to choose from.
