Symptom: While displaying speed dome cameras, the image breaks when the dome turns, and
levels fluctuate dramatically.
Reason: Light levels vary suddenly in the areas that are viewed when the
dome turns.
Solution: Avoid very bright light or glare in the path of the speed dome, or use
a lower speed.
Symptom: When switching cameras, the Call Monitor synchronizes to the new camera very
slowly.
Reason: The monitor's response time (to new video input) is too slow. Usually,
it ranges from 0.03 sec. to 1 sec.
Solution: Use a monitor with a faster response time.
