What is Color Rolling?
Color Rolling means the color of digital image turns from white to blue, pink (or yellow) and return to white
again. Such a phenomenon of circling period is caused by IP Cam ’s DSP of CCD which is used under
traditional alternating current (AC) 50/60Hz of fluorescent light (or gaseous electric light). The fluorescent light
changes constantly due to the strength and color of alternating current are base on the speed of 8.3ms. Thus,
CCD must catch and calculate the correct white balance through DPS. Normally, CCD needs 100~150ms
