DAY/NIGHT OPERATION
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
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 11 and Table F show how the camera switches between color and black-white operation.
