The visual intercom doorbell is the visual doorbell system, which is known as building intercom system. The corresponding non visual intercom doorbell is a kind of equipment that plays the role of communication in buildings.

Visual intercom, also known as visual doorbell, building intercom, nk., is called Video door phone or Video door bell in English. It was introduced from developed countries in the 1990s and has developed rapidly in China. Since the end of the 1990s, it has been mainly used in commercial residential buildings. With rapid development, it has been widely used in middle and high rise residential buildings in urban communities.

When in use, the resident hears the ring tone and, like answering a video phone, accepts the call of the visitor through the host at the downstairs door for dialogue. At the same time, the video extension in the resident’s home can receive the video image through the host camera at the downstairs. The resident observes the monitoring image on the display screen of the extension to confirm the identity of the visitor, and finally decides whether to press the unlock button of the indoor extension to open the electric lock connected to the host at the door, Visitors are allowed to open the door.

Visual intercom is the audio and video communication system between residents and visitors in the residential area. It is the first line of defense against illegal intrusion of residents in the residential area. Through the setting of this system, residents can use intercom/visual intercom extension at home.

They can talk with visitors through the intercom/visual intercom host at the entrance of the unit building and identify visitors through the images on the extension screen. After the visitor is confirmed, the resident owner uses the door lock control key on the extension to open the electric control door lock on the host at the entrance of the unit building to allow the visitor to enter; Otherwise, all personnel and strangers who are not in the unit building are not allowed to enter.

The visual intercom system can also connect the emergency alarm button, infrared detector, door magnetic window magnet, smoke detector, combustible detector and other alarm devices, and timely notify the management center of illegal intrusion, fire alarm, gas leakage, emergency help and other information, so as to provide convenience and safe life for residents, reduce the annoyance of residents who are reluctant to be disturbed, and also reflect the grade of residential quarters and the identity of residents.

We note that the function of visual intercom is mainly embodied in visualization and intercom. The visual intercom requires very high performance of the camera module. If the performance of the camera is poor, the resolution may be low (low pixel), the line of sight may be blurred (backlight), and the camera may be dim (dark night), which will directly affect image recognition and property safety.
