Connect the Power Adapter Cable. Use a driver (-) to screw one part
of the Power Adapter consisting of two lines to the holder.
Connect the Power Adapter’s plug to the Power Outlet.

y As shown in the Table3-1, 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%, AC
