VTC-C770WDR

7.5 DAY/NIGHT

To enter EXPOSURE menu, press button at MAIN>DAY/NIGHT>AUTO...

IMPORTANT!!!

DAY->NIGHT and NIGHT->DAY operations must be examined and verified at the final step

of the installation.

Block the lens for a few seconds for NIGHT mode and release and let it return to DAY mode.

If camera stays at NIGHT mode more than 10 seconds, increase N-->D THRES a little and

repeat the fore-mentioned steps. If the scene is too dim or lens iris was adjusted too low (near

close), it may not return to DAY.

DAY/NIGHT

Default

Descriptions

N-->D

THRES.

N-->D THRES is a threshold level to switch from NIGHT to DAY.

Due to the nature of WDR the image level of the scene is controlled down

and the camera will not switch to DAY despite bright ambience.

Increase the value if it stays in B/W and is required to switch to DAY.

Too high of a value may make ICR repeat between NIGHT<-->DAY.

In that case, slightly reduce the value and try all of the above.

N<-->D

DELAY

N<-->D DELAY is time in seconds while the camera maintains its status before

D<-->N switches.

DELAY can avoid the unwanted/frivolous switching by a short term light.

(I.e. the light from the passing car)

BURST

B/W

OFF

BURST ON B/W determines whether a color burst signal keeps output or

eliminated when camera switches to B/W.

If set to ON, B/W video signal contains color burst signal and is more

compatible with the color equipment but shows the same resolution as color

video.

If set to OFF, the color burst signal is removed from B/W video and shows

better resolution.

Rarely a compatibility problem may occur with the color equipment.
