Example 2: Connect a quad monitor (used as a slave monitor)
A quad monitor supports four camera connections. The screen can display 4 cameras
simultaneously or one camera at a time.
The L164/L174V is a four channel DVR that records four channels of video. It also performs the
function of a quad monitor.
If you already have a quad monitor with cameras connected to it, this is the best solution for
connecting your DVR:
1) Connect your camera video output to the video input of the DVR.
2) Then connect your video output from the DVR to the video input of the quad monitor.
Under this setup the quad monitor simply acts as a slave monitor and the on screen display of the
DVR will appear on the monitor.
MONITOR CONNECTION :

DVR.
2) Repeat this procedure for the rest of the channels.
