NOTE: The illustrations and descriptions in the following section refer to the 16-channel model.
Connecting the Video Input
Connect the RJ-12 cables from the modular cameras to the modular RJ-12 connectors.
Connect the coaxial cables from the video sources to the BNC Video In connectors. (16-Channel Model Only)
Connecting the Monitor
A VGA connector is provided so that you can use a standard, multi-sync computer monitor as your main monitor. Use
the cable supplied with your monitor to connect it to the DVR. The VGA monitor is automatically detected when you
connect it.
NOTE: It is possible that the DVR will not automatically detect a VGA monitor if the monitor does not support
the auto detect function. In this case, press and hold the DISPLAY button on the remote control for 5 seconds or
longer to switch the video output to VGA out. Pressing and holding the button for 5 seconds or longer again returns
to the composite video output mode.
If you prefer to use a standard CCTV monitor, connect it to the Video Out connector.
NOTE: The DVR does not support simultaneous operation of a CCTV and a VGA monitor.
Connecting Alarms
NOTE: To make connections on the Alarm Connector Strip, press and hold the button and insert the wire in
the hole below the button. After releasing the button, tug gently on the wire to make certain it is connected.
To disconnect a wire, press and hold the button above the wire and pull out the wire.
AI 1 to 16 (Alarm-In): You can use external devices to signal the DVR to react to events. Mechanical or electrical
switches can be wired to the AI (Alarm-In) and GND (Ground) connectors. The threshold voltage for NC (Normally
Closed) is above 4.3V and for NO (Normally Open) is below 0.3V, and it should be stable at least 0.5 seconds to be
detected.
GND (Ground): Connect the ground side of the alarm input and/or alarm output to a GND connector.
NOTE: All the connectors marked GND are common.
