When the resistance value of copper wire is at [20°C(68°F)]
Copper wire size (AWG)
Resistance value(—/m)
Voltage Drop (V/m)
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.
Standard voltage for camera operation : DC 12V±10%, AC 24V±10%
There may be some deviation in voltage drop depending on the type of wire and the
manufacturer.

Be sure to connect power only after all the installation is complete.
Control via RS-485 Interface
The camera can be controlled by using external controllers like a Remote controller. (RS-485
Communication)
(1) To control by PC
Connect the RS-485 control port of the camera and the serial cable through an RS-485
converter.
Example) PC Serial Port (COM1)
(2) To control using a DVR or System Controller
Connect the RS-485 cable (TRX+, TRX-) to the connection port of the 485 control board
that is connected to the DVR or System Controller.
