1. Visitors can easily call and talk to the residents through the host computer in front of the downstairs unit. Residents can control the switch of the unit door indoors, and the host computer in the community can receive the alarm signal of residents at any time and send it to the host computer on duty to inform the community security personnel. The system not only strengthens the safety precautions of high-rise residential buildings, but also greatly facilitates residents and reduces many unnecessary troubles of going upstairs and downstairs.

Second, the security department of residential property management can monitor the work of the security intercom system of each residential building in the residential area through the management host of residential security intercom.

For example, the property department informs residents to pay various fees, residents inform the property management department to maintain the facilities in the community, and residents report to the community or neighborhood Committee managers for help in case of emergency.

The system can be used for communication between residential property management departments and households or between households.

Furthermore, if the entrance door of the residential building is illegally opened and the security intercom host or line fails, the community security intercom management host will send out an alarm signal and display the alarm content and location.

Third, the doors of the building are always locked at ordinary times to prevent people in the building from entering the building without permission, and residents in the building can freely enter and leave the building with their keys.

When guests visit, they need to press the room number of the visited household on the intercom keyboard outside the building door and call the intercom extension of the visited household.

The owner of the visited household makes a two-way call or visual call with the visitor through the intercom equipment, and confirms the identity of the visitor through the voice or image of the visitor.

After confirming that visitors can enter, the owner of the household uses the unlock button on the intercom extension to control the electric door lock on the entrance door of the building to open, and the visiting guests can enter the building.

After the visiting guests enter the building, the door of the building locks automatically.
