How the building intercom system works

The door is always locked, so that non-residents can enter the building without permission. The residents in this building can use the key to enter and exit the building freely. When a guest visits, guests need to click on the room number of the intercom host on the intercom keyboard outside the building to call the intercom extension to visit the resident. The owner of the interviewed household makes a two-way or visual call with the visitor through the intercom device, and confirms the identity of the visitor through the voice or image of the visitor. After confirming that the visitor can be allowed to enter, the owner of the household uses the unlock button on the intercom extension to control the electronically controlled door lock on the entrance door of the building to open, so that the visitor can enter the building. After the visitor enters the building, the door is automatically locked.

The security department of the residential property management can monitor the working conditions of the security Intercom System of each residential building in the community through the community security intercom management host. If the entrance door of the residential building is illegally opened, the security intercom host or the line fails, the cell security intercom management host will send out an alarm signal and display the content and location of the alarm. The community property management department and the household or household and household can use the system to talk to each other. If the property department informs the tenants to pay various fees, the tenants inform the property management department to repair the residential facilities, and the residents call the community management personnel or the neighborhood for help in an emergency.
