1. VCR in :
This BNC connector is connected to video output from VCR/DVR. A pre-recorded quad screen signal from a
tape can be played back through a VCR/DVR and displayed on the video output channels. Push the VCR
button (#2) to switch the device to VCR Playback mode.
2. VCR out :
This BNC connector is to be connected to the Video in from your VCR/DVR. It will only provide a quad screen
video to ensure an un-interrupted video recording for all four cameras. The display video is not affected by
the control panel.
3. Terminations :
These impedance switches are used to provide proper termination for each camera input. These switches
toggle between 75
Ω
and Hi-Z impedance. Incorrect termination will degrade the quality of the video signal.
All video inputs not “looped through” to another device, the corresponding switches need to be set to 75
Ω
termination position. If another device is connected to video out loop through connector set the
corresponding termination switch to Hi-Z position. Any device connected to the video out loop through
connectors needs to be configure to 75
Ω
video termination. The factory default termination setting is 75
Ω
.
4. Ch1 In, Ch2 In, Ch3 In, and Ch4 In Video IN connectors
