Networking type building visual walky-talky system based on 3G technology

Abstract

A networking type building visual walky-talky system based on the 3G technology. The networking type building visual walky-talky system comprises a talkback gate host, an indoor extension set, an enclosing wall machine and a management machine, wherein the talkback gate host, the indoor extension set, the enclosing wall machine and the management machine are in 3G network communication; the management machine is further communicated with an owner mobile phone through a 3G network. The building visual walky-talky system further has three modes to carry out identification on identity information of users, and the three modes comprise identification of property working staff, identification of owners, and identification of visitors. According to the networking type building visual walky-talky system based on the 3G technology, special wire cables are not needed to be laid, communication is stable, and safety and convenience of the owners are improved.

Description

Technical field: [0001] The present invention relates to a building visual intercom system, more specifically, relates to a networked building visual intercom system based on 3G technology. Background technique: [0002] Building intercom has been developed in my country for more than 20 years, and the product types are rich and perfect. At present, many residential quarters, office buildings and other buildings have installed building video intercom systems. Although semi-digital and full-digital TCP / IP products have been vigorously promoted in recent years, the mainstream products are still analog products. At the same time, with the continuous expansion of the scale of the community, the networked building video intercom system began to emerge in large communities. The call and door opening function between the machine and the fence machine. However, the problems of traditional analog products in transmission become more and more prominent. At present, the building in...

AI Technical Summary

Problems solved by technology

The signal transmission is greatly affected by the transmission distance, and there are the following problems in long-distance transmission in a large cell: 1. The farther the networking distance is, the more likely the system will encounter the problem of lightning electromagnetic compatibility, and the equipment is easily damaged

2. Long-distance transmission of networked analog video, audio, and data is easy to attenuate, resulting in blurred visual images and loss of color, and the sound becomes smaller, prone to interference sounds, and at the same time causes unstable communication

3. It is necessary to lay special cables, and at the same time, in order to reduce the attenuation of analog signals (video, audio, data) in long-distance transmission, it is necessary to increase the diameter of the cables, which not only destroys the original environment of the community, but also increases the construction cost ,Material costs
