LOOPING VIDEO OUT
The DVR5100 supports looping video for all analog inputs. It passes the video input to a monitor or other analog video device.
To use looping video:
1. Connect a coaxial cable to the video out connector on the rear panel.
2. Connect the other end of the coaxial cable to the analog device.
3. After installation, turn off the termination for the video channel.
4. If you are looping video to additional devices, set the termination to Hi-Z on each device to disable termination. Set the termination to
75 ohms on the last device to enable termination.
NOTE: Ghosting or other imperfections may appear in the video signal if you do not terminate the video signal at the last device in the series.
CONNECTING AUDIO
The DVR5100 supports up to four audio inputs as follows.
• Two audio inputs are provided for a 4- or 8-analog input DVR (DVR5104, DVR5108).
• Four audio inputs are provided for a 16-analog input DVR (DVR5116).

associated with one or more video inputs. Refer to Basic Camera Setup on page 43 for information on configuring audio inputs.The unit supports
line-level inputs. Microphones must be amplified for best results.
