Background
With the development of science and technology, the security camera equipment technology is more mature. From indoor to outdoor, from local storage to wireless remote transmission, various security protection equipment emerges endlessly.
In the prior art, a security camera usually needs to take a picture or a video and store the picture or the video in a preset SD card or other storage media, and then transmits an image file shot in the storage media to a remote device for storage and backup. However, since the intruder has a high degree of tracking-prevention alertness, measures are rapidly taken to destroy the image pickup apparatus if it is found that it is photographed. In order to solve the problem that the image data can be stored after the device is damaged, a general imaging device adopts a method of continuously imaging for a long time and transmitting the image to a different place for storage. The long-time operation of the image pickup apparatus causes problems of high power consumption, heat generation, high storage demand, high traffic, and huge workload required for searching for image evidence afterwards. Therefore, a plurality of camera devices with modes of human body induction, shooting after motion detection and the like appear, and the problems of high storage requirement, high flow and huge workload required for searching image evidence afterwards are basically avoided. However, the camera still needs to be in a working state for a long time, the problems of power consumption and heating still exist, the real-time video is transmitted back only after the user sends an instruction at present, and the camera does not actively send the real-time video stream to a product on the handheld device after detecting a person, so that the camera still is very inconvenient for outdoor working camera devices.
Therefore, enterprises design corresponding equipment for the situation, for example, the chinese utility model with publication number CN 210781068U discloses an infrared sensing camera device for real-time video transmission through a mobile network. The scheme describes the principle of sending real-time video through a mobile network after infrared induction shooting.

Meanwhile, all the problems that the power consumption is high, the heat is generated, the storage requirement is high, the flow is high, huge workload is needed for searching image evidence afterwards, the image evidence is easy to damage as the image arrives at the remote equipment slowly, or a user of the camera equipment cannot observe illegal behaviors occurring in time are solved.
