Working principle of visual doorbell

Visual doorbell system is a kind of equipment used for information transmission inside and outside high-rise residential buildings and apartment buildings, security door control and alarm to building duty room by residents in emergency. It is well received by users for its complete functions, reliable performance, large capacity, beautiful appearance and convenient installation and use, and has also been widely used in safe living areas.

Visitors can conveniently call and talk to the residents through the host computer in front of the downstairs unit. Residents control the switch of the unit door indoors, and the host in the community can receive the alarm signal of residents at any time and send it to the host 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.

The door of the building is always locked at ordinary times to prevent people who are not 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.

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 security intercom management host. If the entrance door of a residential building is illegally opened and the security intercom host or line fails, the community security intercom management host will send an alarm signal and display the alarm content and location. The system can be used for communication between residential property management departments and households or between households. 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.
