SW-D8000U, 16CH. COLOR VIDEO MULTIPLEXER
JVC PROFESSIONAL, IMAGING PRODUCTS 69
In Figure 3, the camera’s lens or its AGC is out of adjustment, resulting in high luminance levels. As
a result, detail in the scene is likely to be lost during multiplexed recording, and video motion
detection will be ineffective.

Benefits of the camera scope:
q
An inexperienced installer can use it to check the input video signals to the multiplexer,
without the need for additional signal measuring equipment and its associated cost. This is
especially useful if intrusion detection is intended.
q
Troubleshooting of the system after installation is simplified.
q
If a problem is reported for the system, the camera scope displays are so simple that a
technical support person who is remote from the site can easily get an untrained person on
the site to describe the camera scopes. This will then enable a diagnosis to be made
without incurring the time and expense of a visit to the site.
4.14 VCR SETUP
This option is used to specify the type of VCR that is connected to the multiplexer. You can also

The choices are:
S-VHS/Composite
Switch Input ON/OFF
Switch Edge
Signal Level
Playback Format
S-VHS OR COMPOSITE VCR
There are S-VHS and Composite video signal VCR’s available. Depending on which type VCR you
are using set the type here.
