Description

A network camera with self-protection based on gravity change

This application claims the priority of an invention patent application filed with the Chinese Patent Office on April 1, 2020, the application number is 2020102513695, and the invention title is "a network camera with self-protection based on changes in gravity". The entire content is incorporated herein by reference. Applying.

Technical field

The present invention relates to the technical field of Internet equipment, in particular to a web camera capable of self-protection based on changes in gravity.

Background technique

The webcam is a new generation of cameras that combines traditional cameras and network technology. It can transmit images to the other side of the earth through the network, and the remote viewers do not need to use any professional software, as long as a standard web browser , You can monitor its images. The web camera is a new generation product that combines traditional cameras and web video technology.

With the construction of Skynet and people's attention to the safety of life and property, the coverage of web cameras has become wider and wider, and can be seen in the streets and alleys of the city. In the cold winter, there is often a lot of snow above the cameras. Since the camera is often installed at a high place, it is very difficult to remove snow manually. The large amount of snow above the camera will not only add a lot of load to the camera, but the camera is covered by snow and ice for a long time, which greatly affects the life of the camera. The snow will cause the camera to take the picture blurry.

Therefore, we propose a self-protection web camera based on changes in gravity. When the camera is compressed by ice and snow, the protection device will be automatically triggered to protect the camera due to the change in gravity, which protects the camera in severe ice and snow weather.
