This allows the operator to keep monitoring the site while playback is in progress.
PC-based or Standalone Security DVR is a Capture Card built inside a computer. These capture boards have 4,8,16 or 32 Channels video input. The security DVR system receives the analog signal from all the cameras; it converts the signal to digital signal and compresses it with
MPG4 compression and then stores the data on the hard drive for
Archiving and playback. The security DVR software provides all the necessary, video and recording functions: like, Video compression, motion detection, converting the Video to a file, CCTV camera controls and display, record and playback functions. One of the advantages of security DVR in comparison to VCR, is the ability to optimize recording. Optimize recording provides more recording time by elimination continues recording of no activity by using motion detection. In addition, there is the ability to identify activity and search without watching hours of recording to find what we want.
To provide us with these efficient features, CCTV DVR systems use advance technology called motion detection by frame analysis. The CCTV DVR system receives the analog pictures from each security camera and then the security DVR analyzes it frame by frame. After an interval time, if the DVR sees that the frames are identical it will stop recording the identical frame, but will keep analyzing and displaying all the frames. If the security DVR detects a change in the frame (and it can be the slightest change frame), it will store the frames that are in the cache and start recording all the frames thereafter. With this process, the security DVR records only the activity with out filling the hard drive with no activity recording. The process makes it very efficient, not just for storage purposes, but for searching and playback. For example: if you see an event recording in the middle of the night you can just click and check this specific activity without watching the whole night recording to find that activity.
