Installation Procedures
Connecting Power
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
• Since the power specification supports both AC and DC, connect AC 24V, 500mA Adaptor or DC 12V, 500mA Adaptor.
High Voltage Type (AC230V, 50Hz) 
• Use AC230V, 50Hz power source For SHC-745PH.
When the resistance value of copper wire is at [20¡C(68¡F)]
Copper wire size(AWG) | #24(0.22mm2) | #22(0.33mm2) #20(0.52mm2) | #18(0.83mm2) | |
Resistance value(Ω/m) | 0.078 | 0.050 | 0.030 | 0.018 |
Voltage drop(V/m) | 0.028 | 0.018 | 0.011 | 0.006 |
•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.
Control via RS-485 Interface
The camera can be controlled by using external controllers like a Remote controller.
