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.
About Connection Cables
Installation and connection
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
• Turn OFF the power supply to all components before making connections.
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.

1.
Remove the dome cover
Hold the bottom of the unit and turn the
dome cover counterclockwise.
2.
Pull the label part downwards and
remove the dome cover.
3.
Open a hole of ø140mm in the ceiling.
MEMO
There is no need to open a hole in the ceiling
when extracting the cables from the cable
extraction hole on the camera side.

See page 8)
4.
Mount the electrical box.
This unit can be mounted with a 4 inch
square electrical box. For mounting an
electrical box, consult your dealer of pur-
chase.
5.
Mount the drop prevention wire.
In order to prevent the unit from falling
for any reason, connect the drop pre-
vention wire to the ceiling slab, etc.
6.
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.
8.
Connect the video signal cable
(BNC connector).
