Abstract

The invention discloses a decoder for video monitoring, and the decoder comprises a shell; a partition plate is fixedly installed in the shell, an air inlet is formed in the front wall of the shell, a heat dissipation cavity is formed in one side of the partition plate and communicates with the air inlet, a communicating hole is formed in the partition plate, the heat dissipation cavity is communicated with an inner cavity of the shell through a communicating hole, a motor is fixedly installed in the heat dissipation cavity, a first rotating shaft is installed at the output end of the motor in a transmission mode, and fan blades are fixedly installed at the end, away from the motor, of the first rotating shaft; air in the inner cavity of the shell is sucked into the heat dissipation cavity through the communicating hole under the injection action and then exhausted from the heat dissipation cavity, so heat dissipation of electronic components in the inner cavity of the shell is achieved; the transmission mechanism is driven under the magnetic attraction action, and the driving mechanism does not need to make contact with the transmission mechanism, so noise generated during driving is reduced, and the use is quieter.

Description

technical field [0001] The invention relates to the technical field of decoding equipment, in particular to a video monitoring decoder. Background technique [0002] A decoder is a hardware / software device that can decode and restore digital video and audio data streams into analog video and audio signals.
