Pelco C3425M-D manual Auto Iris Level Adjustment, SW4-4 Flickerless, SW4-6 Reserved

SW4-4: Flickerless

In certain lighting conditions, a flicker in the light source may affect camera operation. Flickering can be caused by a number of conditions, including the quality of the source power and the age and type of fluorescent bulbs and ballasts.

Set to ON to enable flickerless operation. The camera will remove the effects of flickering when present. The shutter speed will be set to 1/120 (NTSC) or 1/100 (PAL).

Set to OFF to disable flickerless operation. This is the default.

NOTE: If you enable flickerless operation, you should use AC line lock for best results.

SW4-5: AWB (Auto White Balance)/MWB (Manual White Balance)

Auto white balance is enabled by default (OFF).

To manually set and lock the white balance:

1.Set SW4-5 to OFF.

2.Hold a white background in front of the lens until the video shows all white.

3.While holding the background in place, set SW4-5 to ON. A blue blinking block appears on the video image for a few seconds. When the block changes to solid green, the manual white balance process is complete.

SW4-6: Reserved

Do not change SW4-6 from its factory setting. SW4-6 must be set to OFF for Varifocal models; it must be set to ON for fixed-iris lenses.
