The application of artificial intelligence technology is an important trend in the development of security industry at present，Many domestic building talkback manufacturers have begun to integrate artificial intelligence into the building talkback system，On the basis of the original access control intercom, new face recognition, fingerprint recognition, voice recognition and other biometric technology applications，It greatly improves the user experience of the product，The product is more convenient, comfortable and safe in actual use。

So far, the building video intercom products have been from a simple call, unlocking and other functions to anti-theft alarm, information release and other functions of the leap, from the previous black and white machine visual intercom development into the color machine visual intercom, it can be said that the development of products more and more mature。伴随着人民生活水平的不断提高，住户对小区的安防管理和物业管理的要求也就越来越高了！因此，楼宇可视对讲产品仅仅提供以上功能已经不能满足智能化小区继续发展的需要。Through market research, it is found that today's people's main demand for video intercom products has the following aspects: 

No matter in the family, or in the community, intelligent building intercom system plays an important role, is one of the indispensable security products。With the drive of 5G, Internet of Things, artificial intelligence and other emerging technologies, intelligent building intercom is no longer a single product, but has formed a complete system, integrating linkage video surveillance, smart home, anti-theft alarm, intelligent parking and other systems to achieve intelligent connectivity。

accuracy。Accuracy is the top priority of the security system, when there is an emergency, the system accurately receives the information of the security sensor and gives the correct response or prompt。Due to the network transmission process of the security system, packet loss may lead to misjudgment. Therefore, the system design must be considered as comprehensively as possible to improve the system performance and ensure the high accuracy of the system at the software level。

Intelligent community, in a broad sense, is the use of modern building technology and modern computer, communication, control and other high-tech, the property management, security, communication and other systems integrated together, and through the communication network connected to the property management office, for the community residents to provide a safe, comfortable, convenient modern living environment。In a narrow sense, it includes residential automation system, family information service system, property management system and community public service system。

The community management center realizes the unified access and centralized management of the information communication network in the community management center, which is the total exchange, distribution and management center of the whole community information network。The telecommunication service exchange center of the whole community is set up in the telecommunication service section, which is connected with the remote module of each block through optical fiber, and unified access to the urban telecommunication public network。A general front end is set up in the cable TV part to carry out unified processing such as urban cable TV signal access, satellite signal reception, and broadcast of self-run programs. At the same time, signals are sent to each block through optical fiber。It is the core of the whole community information network to set up the central computer room in the broadband information network
