Cause (Information)
Remedy
Is there a problem in the power cable(s) connecting the 
camera to the power supply unit?
(If the power cable(s) are too long or of an inadequate 
size, the correct voltage may not be supplied due to an 
increase in cable resistance.)
Use cable(s) with low cable resistance 
and of the correct cable length.
(Ensure that the voltage supplied to the 
terminal board is correct during camera 
operation, i.e. when the rated current is 
flowing through the camera.)
Are cables connected properly to the terminal board on 
the Ceiling Mount ?
Is there a problem with the power cable(s) connecting the 
camera to the power supply unit?
(If the power cable(s) are too long or of an inadequate 
size, the correct voltage may not be supplied due to an 
increase in cable resistance during the pan/tilt operation.)
Change power cable(s) to one(s) of lower 
resistance (i.e. thicker or shorter cable(s)).
(
