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.
Be sure to connect power only after all the installation is complete.
Ground should be connected to the GND terminal.
