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.)
Power cannot be turned 
on.
Are cables connected properly to the terminal board on 
the Ceiling Mount ?
Connect the cables properly.
Power can be turned on 
but it later turns off 
when the pan/tilt 
mechanism starts 
operation.
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 with of 
lower resistance (i.e. thicker or shorter 
cable(s)).

Video sync error occurs.
●When LL is set, does the power supply frequency match the 
video frequency (PAL: 50 Hz, NTSC: 60 Hz)?
●Is there any serious noise interference in the power 
supply?
●Use a stable power supply with a 
matching frequency.
●Prevent noise interference from 
occurring in the power supply.
