There are two steps for camera installation.
.Connect the Video Signal Line to the DVR channel input.
.Connect the power adaptor jack to the camera.
The DVR can connect 4 channel’s audio input, but you can only select
one for recording.
To display the DVR picture, the DVR’s video output signal should be
transferred to your TV set or monitor. Any TV set that has a “video input”
terminal is suitable for displaying the picture. The figure above shows
the video and audio signal line connection.
Note: at one time, you can only connect one audio input,
which means, if you connect an audio to cam1, you cannot
connect any of cam2 to cam 4. You should plug them out.
