Symptom Cause (Information) Remedy
Picture is not displayed. 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

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

●Use a stable power supply with a
matching frequency.
●Prevent noise interference from
occurring in the power supply.
