How to design the visual intercom access control system?

This system is an all-digital two-way intercom one-way visual access control system based on bus. The all-digital bidirectional intercom unidirectional visual access control system based on bus adopts digital coding technology and bidirectional communication transmission technology. The whole system can communicate in two directions, that is, the indoor sub-unit can give an alarm to the management center to realize two-way communication with the management center and the building host. Through the video intercom networking system, residents and residential property management centers can establish internal communication channels.

Each portal crane of the system is connected with the management machine through the network cable to realize resource sharing. Through the networking line, visitors can directly call the management center at the door machine, and the management center can display the building number of the call, make a call, ask questions or handle events.

At the entrance of each unit, the unit Chinese networking visual intercom door machine, Chinese LCD display, full digital programming, and low-light black-and-white camera are used. With infrared compensation function at night, the indoor unit can clearly observe visitors in dim environment. The visitor calls the resident through the Chinese prompt on the door machine, and the image of the visitor can be displayed on the indoor extension of the resident. When you make a two-way call with the visitor and confirm the identity of the visitor, you can remotely open the electric lock of the downstairs security door and let the visitor in. The system also has the function of password opening. If the password is pressed incorrectly for three consecutive times, the system will automatically send it to the administrator host to remind the administrator to pay attention.

Because it is an all-digital two-way intercom and one-way visual system, it has strong system functions, such as indoor alarm, call management center, call confidentiality, call time limit, door opening authority control and so on.
