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 : AC 24V ±10% or DC 12V ±10%
*There may be some deviation in voltage drop depending on the type of wire and the manufacturer.
