NOTE: This section only applies to DN model cameras.

DN 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.

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

Figure 22 and Table C show how the camera switches between color and black-white operation.
