The invention discloses an embedded intelligent digital hard disk video recorder for an ATM machine, which comprises a main control module, a video frequency encoding processing module, a video frequency decoding processing module, a program memory module, a VGA module, a push button, an indicating lamp module, an alarm processing module, a digital liquid crystal screen and a series port management and network mouth output module, wherein the video frequency encoding processing module converses video frequency input analog signal into digital signals, video frequency data are encoded and compressed by self-made AVS standard of our nation, and are transmitted to the main control module after intelligently processing, and meanwhile, alarm signal data are intelligently processed through the embedded intelligent recognition algorithm in the video frequency encoding processing module, and analogy audio frequency signals after processing send network data to the client ends through the series port management and network mouth output module. The embedded intelligent digital hard disk video recorder can analyze original video frequency data in real time within 24 hours, identifies on-spotabnormal behaviors of ATM machines, achieves prior early warning, real time alarm and interlocking alarm, and has an intercommunication function, thereby achieving the real time communication of a remote center and an ATM machine spot.
