Abstract

The invention discloses a digital visual intercom system. The digital visual intercom system comprises a residential management server, gate managing units, floor switches and indoor units. The residential management server composes a local area network with the gate managing units and the floor switches through a core switch. The digital visual intercom system is characterized in that the indoor units are handheld devices comprising image display units, voice modules and short-distance wireless communication units; at least one wireless router is connected with every floor switch, and every handheld device is connected with the corresponding wireless router through the corresponding wireless communication unit; every gate managing unit comprises a camera, an image digital module and a voice module. The digital visual intercom system omits special indoor digital units to greatly reduce the system cost and does not need special indoor wire arrangement and installation to reduce the engineering cost; even when being not in, residents can also communicated with the gate management units through remote communication to obtain video information.

Description

technical field [0001] The invention relates to a community access control security system, in particular to a visual intercom system used for community building access control. Background technique [0002] With the improvement of living conditions and the improvement of safety awareness, video intercom systems are being used more and more. Usually, the video intercom system is mainly composed of a community management server, a door management machine, a floor switch and an indoor unit connection. The first-generation video intercom system uses analog circuit wiring. Due to the need to transmit video signals, voice signals and control signals between each machine, the wiring is complicated, the installation process is large, and maintenance and renovation are inconvenient. In view of the above problems, Chinese invention patent CN1909652A discloses a building video intercom system. By setting modulation interface circuits in each control unit, the 3-core wiring connection...
