Description

technical field [0001] The invention relates to an electronic monitoring device, in particular to an ultra-high-definition portable digital video recorder (DVR). Background technique [0002] With the development of electronic monitoring technology, a large number of digital video recorder (DVR) series products have entered the market. DVR has the advantages of large storage capacity, high definition, real-time monitoring, video recording, playback, etc., and has been recognized by consumers. [0003] The core object of DVR monitoring is people, and the image obtained by DVR monitoring is the whole scene. People in the entire scene monitored by DVR are not only very small, but also unclear; if the face image information cannot be clearly recognized, the purpose of monitoring will not be achieved. In addition, the traditional DVR monitoring system is fixed at a certain location to monitor a single scene and cannot be carried. [0004] For portable DVRs, the camera connecti...
