12 V DC
Calculation of the relation among the cable length, resistance, and power supply.
The voltage supplied to the camera shall be between 10.8 V DC and 16 V DC.

Waterproof treatment for the cable joint sections
Adequate waterproof treatment is required for the cables when installing the camera with cables
exposed or installing it under the eaves. The camera body is waterproof, but the cable ends are not
waterproof.
Be sure to use the supplied waterproof tape at the points where the cables are connected to apply
waterproof treatment in the following procedure. Failure to observe this or use of a tape other than
the provided waterproof tape (such as a vinyl tape) may cause water leakage resulting in
malfunction.

Note:
How to wind the supplied waterproof tape
(accessory)
• Stretch the tape by approx. twice (see the
illustration) and wind it around the cable. Insufficient
tape stretch causes insufficient waterproofing.
• To install this product outdoors, be sure to
waterproof the cables. Waterproof grade (IEC IP66
or equivalent) is applied to this product only when it
is installed correctly as described in these operating
instructions and appropriate waterproof treatment is
applied. The mount brackets are not waterproofed.
