In this deployment, the culvert beneath the security fence is protected with the same sensor cable as the fence
but is configured as a separate zone in software.
This also simplifies the protection of
gates and culvert coverings, as the
cable can be looped across them and
configured in software as a separate de-
tection zone.
In addition, ranging capabilities bet-
ter future- proof the system as zones
can be adjusted anytime afterwards to
accommodate for changes in perimeter
infrastructure and usage.
For example, the required zone changes
when a new surveillance camera or gate
entrance is added could necessitate addi-
tional equipment with a block sensor.
With a ranging sensor, the new camera
or gate area is simply a configuration
change in software.
Less Walking, More Troubleshoot-

Ranging provides another practical ben-
efit: the ability to quickly locate sources
of nuisance alarms caused by cut, dam-
aged or improperly installed sensor
cable, as well as damaged, old, or poor-
ly constructed fences.
Loose signs can also cause problems when
flapping in the wind.
Even on a relatively short perimeter, care-
fully inspecting the fence along an entire
zone takes considerable time.
