Since power specifications differ depending on the model, make sure to check your
model name and specifications before connecting power.
You can connect power as shown in the following figure.
For AC / DC power
High Voltage Type (AC230V, 50Hz)
• Since the power specification supports
both AC and DC, connect AC 24V,
500mA Adaptor or DC 12V, 500mA
Adaptor.
• Use AC230V, 50Hz power source For
SHC-745PH.
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)
Serial Cable RS-485 Converter Camera
RS-485 Control Port
(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.

Installation Procedures
Connecting Power
• 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.
When the resistance value of copper wire is at [20°C(68°F)]
Copper wire size(AWG) #24(0.22mm 2 ) #22(0.33mm 2 ) #20(0.52mm 2 ) #18(0.83mm 2 )
Resistance value(Ω/m) 0.078 0.050 0.030 0.018
Voltage drop(V/m) 0.028 0.018 0.011 0.006
Control via RS-485 Interface
• To control the camera by constructing an additional controller, use Pelco-D
protocol or STW protocol (Samsung Techwin protocol).
