M i c r o p h o n e
There are two steps for camera installation:
Ⅰ
. Connect the Video Signal Line to the DVR channel input.
Ⅱ
. Connect the power adaptor jack to the camera.
The DVR can connect up to four channels for audio input, but only one can be selected for output
and recording at any given time.
To display the DVR image, the video output signal should be displayed to the TV set or monitor
connected to the rear panel. Any TV set that has a “video input” terminal is suitable for
displaying
the image. The figure above shows the video and audio signal line connection.
Note:
Only one audio input can be connected at any time. If audio is connected CAM1, audio to
CAM2 to CAM4 must be unplugged.
