CAUTION:
• If thin cables are used (i.e. with a high
resistance), a significant voltage drop
will occur when the unit is at its
maximum power consumption. Either
use a thick cable to restrict the voltage
drop at the camera side to below 10%,
or place the power supply near to the
camera. If voltage drop occurs during
operation, the performance will be
unstable.
• Attach the cable conductors so that they
do not come into contact with the drop
prevention wires.

Video signal cables
Connect the coaxial cables (BNC) to the video
signal output connector (BNC).
Note
Use the 3C-2V or 5C-2V video signal
cable (coaxial cable). The 7C-2V cannot
be used.
DC 12 V or AC 24 V power supply cable
Connect the DC 12 V or the AC 24 V power
supply to the DC 12V/AC 24V terminals on
the terminal board. To prevent connection
errors or a cable disconnection, we recom-
mend the use of lug plates for the connec-
tions.
The following table shows the connection dis-
tances and connection cables provided that
2-conductor VVF cables (vinyl-insulated vi-
nyl sheath cables) are used.

• Do not allow input from both a DC 12 V
and AC 24 V power supply at the same
time.
• When using a DC 12 V power supply,
ensure that the polarities of the cable
are correct.
• The AC 24 V power supply should
conform to the following:
U-type: Class 2 only
E-type: Isolated power supply only

Mount the drop prevention wire.
In order to prevent the unit from falling
for any reason, connect the drop pre-

Pull out the cables from the ceiling.
Before connecting, pull out the power
supply and video signal cables about
10cm from the electrical box.
7.
Connect the power supply cable.
When installing, cover the cable with in-
sulation tape so that it does not become
damaged from contact with surrounding
parts.
In addition, be sure to use a wiring
cable for the power supply cable.
