Abstract

The invention discloses a hard disk video recorder. The video recorder comprises a shell and a circuit board. An anti-interference cover for covering an electronic element area is arranged on the circuit board. At least two first threaded holes are arranged parallel to each long side of the circuit board. The anti-interference cover comprises a body, wherein the body is a hollow cuboid, and the size of the lower bottom surface of the body is the same to that of the electronic element area; and a pair of fixing plates. The fixing plates are arranged on the lower bottom surface of the body in parallel, the pair of fixing plates are arranged at two sides of the body symmetrically, at least two second threaded holes corresponding to the first threaded holes are arranged on the fixing holes, and bolts penetrate the first threaded holes and the corresponding second threaded holes, thereby fixing the anti-interference cover on the circuit board. According to the video recorder, the anti-interference cover for covering an electronic element cover is arranged on the internal circuit board, the times of accidental restart or crash resulting from electromagnetic interference is reduced, the operation experience of the hard disk video recorder is better, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the field of monitoring equipment. More specifically, the present invention relates to a hard disk video recorder. Background technique [0002] Hard disk video recorder is a digital video recorder. Compared with traditional analog video recorders, it uses hard disk video recording, so it is often called hard disk video recorder, also known as DVR. It is a computer system for image storage and processing, with functions of long-term video recording, audio recording, remote monitoring and control of image / voice. DVR uses digital recording technology, which is far superior to analog monitoring equipment in terms of image processing, image storage, retrieval, backup, network transmission, and remote control. DVR represents the development direction of TV monitoring systems and is The product of choice for surveillance systems. [0003] In the process of using the hard disk video recorder, it is inevitable to encounter many sudd...
