2. Video and Audio Connection The DVR can support up to 8 cameras video input at the same time.
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 4 channel’s audio input, but you can only select one for recording.
To display the DVR image, the DVR’s video output signal should be displayed to your TV set
or monitor. 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: at one time, you can only connect one audio input, which means, if you connect an
audio to cam1, you cannot connect anyone else from cam2 to cam 4.
