When the resistance value of copper wire is at [20˚C(68˚F)]
Copper wire size (AWG)
Resistance (Ω/m)
Voltage Drop (V/m)
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.
Notes
• Be sure to connect power only after all the installation is complete.
• Use the UL listed, CLASS 2 power transformer for 12v adaptor.
