Large Installations

In large installations that have hundreds or thousands of cameras, it is often necessary to allow
many security personnel to access each camera in full-motion video on demand. This usually
requires an analog video cross-point matrix switch that is in turn connected to several analog
video monitors as well as to digital video storage hardware. The following diagram illustrates
the use of the LongReach 16 in such a configuration.

In the above configuration, the UTP/UTP version (500120) is used in conjunction with the
CCTV Screw Terminal Balun (500009) to provide a total UTP cabling solution between the
matrix switch and the cameras.
