Visual intercom access control Internet-of-Things system

Abstract

The invention provides a visual intercom access control Internet-of-Things system. The visual intercom access control Internet-of-Things system comprises an Internet-of-Things platform subsystem, a function application subsystem and a monitoring protection subsystem; the Internet-of-Things platform subsystem provides cloud computing platform services and includes an alarm receiving server, a community medical service management server, an estate management server, an e-commerce server and the like; the function application subsystem realizes various kinds of function servers by means of an intelligent gateway; the monitoring protection subsystem comprises at least one communication node used for monitoring illumination, smoke and fire alarm and access control parameters in a building; the communication nodes are connected with a centralized controller; and the centralized controller is connected with a video monitoring management center server, an intercom and alarm management center server, an all-purpose card management center server and firewall and switch network equipment. The visual intercom access control Internet-of-Things system has the advantages of high stability, functional completeness, high compatibility and convenience in use.

Description

technical field [0001] The invention relates to a security system, in particular to a visual intercom access control Internet of Things system. Background technique [0002] As far as the video intercom industry is concerned, the digital system has gone through the following different stages: [0003] The first stage was Motorola's smart building project. Later, the technology was dispersed to several companies in the traditional intercom industry, forming the first stage of digital intercom. Due to the limitation of chip technology and multimedia technology at that time, the digital system at this stage had too much power consumption, serious heat generation, and easy to crash. [0004] The digital intercom system of the second phase VoIP solution, its audio is an internally integrated echo cancellation algorithm, and the performance of the video in terms of dynamic images is relatively poor, and there will be mosaics and jagged phenomena when the image changes greatly, an...

AI Technical Summary

Problems solved by technology

Due to the limitation of chip technology and multimedia technology at that time, the digital system at this stage consumes too much power, generates serious heat, and is prone to crashes.

[0004] The digital intercom system of the second phase VoIP solution, its audio is an internally integrated echo cancellation algorithm, and the performance of the video in terms of dynamic images is relatively poor, and there will be mosaics and jagged phenomena when the image changes greatly, and the initial version only supports CIF resolution

[0005] The third stage SoC solution digital intercom system is developed with the development of multimedia technology and communication technology, as well as the maturity of multi-core CPU technology. It has low power consumption and powerful functions, but there is no free communication and agreement between different equipment brands. Poor compatibility, single product function
