When the resistance value of copper wire is at [20°C(68°F)]
Copper wire size #24
(AWG) (0.22mm2)
Resistance ( /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 af-
fect 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.
