Intelligent building visual intercom system principle

With the centralization of economic activities, residential and high-rise buildings in the city have sprung up. In order to ensure the comfort and safety of living and working in the house and the building, and the information processing inside and outside the building, the intelligent building Video Intercom System was born...

The intelligent building video Intercom System is mainly used to provide two-way conversation between the residents in the building and the foreign visitors. At the same time, the camera installed through the door shows the image of the foreign visitors to the residents, and makes judgments for the residents to let the visitors enter.

The principle of intelligent building visual intercom system Intelligent building visual intercom system consists of three parts: wall machine, main machine and auxiliary machine. The actual composition is probably every intelligent community. There is a management center with central management machine (ie The total management machine), the larger cell can also partition the slice. Each zone is managed by a management machine for its designated scope, called a sub-management machine; for the convenience of management or the timeliness of handling events, some communities have a management office in each building, and a management machine is installed. The role of the management machine is to ensure that the property management office and the households communicate with each other, and can remotely unlock the visitors, record the incident, authorize the access control, and process the property SMS.
When a guest visits, the guest needs to use the interviewed host room number outside the building door to make a two-way or visual call with the owner, and confirm the identity of the visitor through dialogue or image, such as the owner's permission. When the visitor enters, the unlocking button on the intercom extension is used to open the electronically controlled door lock on the entrance door of the building, so that the visitor can enter the building. After the visitor enters, the door is automatically locked.
The residential property management department monitors the working conditions of the intercom systems of each residential building in the community through the community intercom management host. If the entrance door of the residential building is illegally opened and the intercom system fails, the intercom management host will send out an alarm signal and display the content and location of the alarm.
