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(0.22mm 2 ) #22(0.33mm
Resistance value(Ω/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.
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.
Note
