SW1-8 Day/Night Operation DW models only

SW1-8: Day/Night Operation (DW models only)

NOTE: On CW models, SW1-8 is unused and does not affect camera operation.

DW model cameras regularly check the brightness level of the ﬁeld of view to determine when to switch between day (color) and night (black-white) operation. Use SW1-8 to set the general light levels at which the camera will automatically switch.

Set to ON (dark) to use standard thresholds to switch between color and black-white operation. This is the default.

Set to OFF (dusk) to use higher light thresholds to switch between color and black-white operation.

Actual brightness threshold levels are affected by camera angle, amount of zoom, ﬁ eld of view, lens, and type of lighting. The switching process lasts from seven to 10 seconds.

Figure 13 and Table B show how the camera switches between color and black-white operation for each setting.

NOTE: These switching thresholds are approximate and were measured using a 3.0 mm to 9.5 mm lens at F1.0. Use the thresholds in Table B as a guide when installing the unit.

AUTO IRIS LEVEL ADJUSTMENT

The electronics of the IS110-DW and IS110-CW Series Camclosures automatically adjust the camera to the auto iris. Auto iris level adjustments are not necessary.
