Multiple video switchers
b - 2 • • • Senstar 100 Installation guide
Each Senstar 100 control unit can be configured to automatically display any
camera input to multiple VS on up to eight CCTV monitors.
Cascaded video switchers
The monitor outputs from remote video switchers can be cascaded to the camera
inputs of a VS in a centralized control and maintenance facility. Cascading the VS
enables the video signals from remote locations to be carried to a central facility
on a single video line. This significantly reduces the expense of video cabling
between locations.
Figure b-2 : Cascaded video switchers, page b-3
depicts two
cascaded VS. Monitor output 1 of VS 2 is cascaded to camera input 9 of VS 1.
In the following sample illustration, the Senstar 100 control unit receives an
alarm input from zone 16. In response, the control unit automatically displays the
camera view for zone 16 (VS2, camera 34) on central control facility monitor 2.
