Connecting Power
Since power specifications differ, depending on the model, make sure to check
the model name and exact specification before connecting power.
Connect power as shown in the following figure.
Low Voltage AC / DC Power
• Check the standard power requirement before connecting to power.
Dual Power Type
(AC 24V/DC 12V, AC 24V Class2)
DC Power Type (DC 12V, 500mA)
When the resistance value of copper wire is at [20¢ª C(68¢ª F)]
Copper wire size(AWG)
#24(0.22mm
Resistance value( /m)
0.078
Voltage drop(V/m)
0.028
• As shown in the table above, voltage decreases as the wire gets longer.
Therefore use of an excessively long adaptor output line for connection to
the camera may affect the performance of the camera.
¡ØStandard voltage for camera operation : DC 12V¡¾ 10%, AC 24V¡¾ 10%
¡ØThere may be some deviation in voltage drop depending on the type of wire
and the manufacturer.

Control via the RS-485 Interface
The camera can be controlled by using an external controller equipped with
RS-485 communications.
• To control using a DVR or keyboard controller
Connect the RS-485 cable (TRX+, TRX-) to the connection port of the 485
control board in the DVR or controller.
