cupboy 0 Posted November 18, 2010 example: This DVR is capable of a real-time display rate of 120 IPS at 360 x 240 resolution (NTSC), and 100 IPS at 360 x 288 resolution (PAL). It has a video recording rate of 30 IPS at 720 x 480 res. (NTSC), and 25 IPS at 720 x 576 res. (PAL), with the ability to select lower IPS/resolution. This enables the DVR to save considerable hard drive space with the ability to prioritize recording between high risk areas and low risk areas.

Soundy 1 Posted November 18, 2010 Images Per Second. Generally used interchangeably with FPS (Frames Per Second), although that's not technically accurate. When a DVR lists specs like that, remember that that number (120 IPS) is split across multiple inputs and usually refers to the maximum for ALL inputs combined. NTSC video spec is 30fps; PAL is 25fps. That's the specification for the video itself and no electronic trickery in the DVR will improve on that. Share this post Link to post Share on other sites
