Resistance value(Ω/m) 0.078 0.050 0.030 0.018
Voltage Drop (V/m) 0.028 0.018 0.011 0.006
y 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.
