1Introduction
The Digital Video Recorder(DVR) compresses the 4 channel of camera input data into the MPEG4 video file and the 4 channel of voice input data into the ADPCM audio file in the real time to record them in the Hard Disk or retrieve them from the Hard Disk simultaneously.
In addition, it transfers the Video/Audio out through a network in the real time and it is able to monitor the Video/Audio remotely by your PC.
