The Recording Capacity of DSR:

* DSR use advanced wavelet compression technology for real time video compression
* The average compressed frame size of a CIF resolution image (384x288 PAL, 320x240 NTSC) is about 8 Kbytes. And the average frame size of a QCIF resolution image (192x144 PAL, 160x120 NTSC) is about 3 Kbytes
* The maximum frame rate is 30 fps for NTSC system, and is 25 fps for PAL system
* However, when frame rate above 8 fps, the video will perform as real time like video
* The basic DSR configuration provides a 6GB hard disk for video recording
* Following is the equation that can be used to estimate the recording time of DSR
