Description

Technical Field

[0001] The utility model relates to the technical field of intercom communication, in particular to a low-power consumption intelligent visual doorbell system. Background Art

[0002] The video doorbell system is a device used for information transmission between households inside and outside high-rise residential buildings and apartment buildings, anti-theft door control, and residents to report to the building duty room in an emergency. It is popular among users for its complete functions, reliable performance, large capacity, beautiful appearance, easy installation and use, and has also been widely used in safe living communities. Through the video doorbell, visitors can easily call and talk to residents through the host in front of the door. Residents can view visitors in front of the door in real time, which can also play a role in anti-theft. However, the existing video doorbell uses P2P protocol penetration through the Internet network to answer, and the delay is significant. When someone rings the doorbell at the door, it generally takes more than 3 seconds for the mobile phone to receive relevant information prompts, and due to factors such as the local network environment and the efficiency of the P2P server, the information received by the mobile phone may be delayed longer, which causes visitors to press the doorbell multiple times, consumes more power, and virtually increases the cost of use.
