No.: Camera number.
Speed: Frame rate in frames (images) per second (FPS) for continuous recording. The speed is limited by
the maximum total recording capacity of the DVR as allocated across all the installed cameras, with an
upper limit of 30 FPS (NTSC – 25 PAL) per individual camera (real time recording). The DVR is capable of
recording 480 CIF (352x240) sized frames per second (NTSC; 400 PAL); each 704x240 image (2 CIF) per
second requires allocation of two of those CIF frames from the overall capacity of 480 CIF frames, and
each 704x480 image (D1 or 4 CIF) per second requires allocation of four of the CIF frames from the overall
capacity. Thus the DVR can record a combination of CIF, 2 CIF and 4 CIF images, with different
combinations of image size/resolution and different FPS rates on different cameras, so long as the total CIF
equivalents allocated is not greater than 480 CIF per second. Choices for possible record speeds are 30,
15, 10, 7.5, 5, 1 and 0 FPS.
Examples:
2 cameras/4CIF/30FPS plus 5 cameras/2CIF/15FPS plus 9 cameras/CIF/10FPS:
2x4x30+5x2x15+9x1x10= 240+150+90 = 480
2 cameras/4CIF/30FPS plus 2 cameras/2CIF/30FPS plus 12 cameras/CIF/10FPS:
2x4x30+2x2x30+12x1x10= 240+120+120 = 480
