3. Rear Port Specification and Connection Examples
Camera Input
The camera connections are the input ports for the video signal(s) used with the DVR. You may use any
video source (75ohm) that outputs via a BNC connector (Twist Lock Type). If your video source outputs
via RCA/Composite video, the proper adapter must be used when connecting the cable to the camera
connection input port(s) of the DVR. Both NTSC and PAL signals are automatically detected by the DVR
and requires no further configuration.
Figure 8 Camera Connection
Connect the cameras to the Video In ports located on the rear panel of the DVR using the proper cables
and connectors (BNC Twist Lock). The corresponding video channels can be "looped" out using the
"loop out" ports located beneath each video input port. There is no need for terminators to be installed,
each port is self terminated. Both NTSC and PAL signals are automatically detected by the DVR and
requires no further configuration.
