A satellite digital video recorder or DVR, captures a satellite TV signal for storage on the internal hard drive and playback for a connected television. The signal passes through a coaxial cable connection to the DVR. Connecting a security camera allows you to record an area under surveillance to the DVR, or simply monitor an area on a TV connected to the DVR without recording. Use a pair of coaxial cables with threaded RF couplers at the ends.

4 Connect the second output cable of the DVR to the RF input on the TV set or monitor.
5 Connect the power to the three components and tune the DVR to channel three or four, depending on the model of the camera.
