Connecting to Power

The recommended adaptor specification for SIR-4250N/P is DC 12V/4A. Please check the standard power requirement before connecting to power.

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%

There may be some deviation in voltage drop depending on the type of wire and the manufacturer.

Notes

•Please must be used adaptor that meets the standard requirement.

•Please connect the power after installation.
