2. Access control system
The video access control system is composed of unit access control, visual intercom, back-end management system and public security network. The voice of the intercom system should be clear, the image should clearly show the facial features of the personnel, the unlocking function should be normal, and the prompt information should be reliable, timely and accurate.
When some unexpected events occur, the system should be able to take photos and video, record the video of the first 10 seconds and the last 10 seconds of the event, and the photos should be real-time photos of the event.
The system supports the access of fire alarm signals. When a fire occurs, the system can record events and linkage the access control to enter the normally open state. The system can query the event records of the access control according to a variety of conditions, and can also view the scene photos and videos when the event occurs.
