Site Survey
Conduct a site survey to ensure that site conditions are suitable for a FlexPS sensor system. The
primary concern is the condition of the fences and gates.
Indicate the following on the site plan:
•
The locations of existing structures (include fences, gates, buildings, roads, etc.). Verify that
mounting surfaces comply with established standards for installation and stability.
•
The locations of obstacles such as vegetation and trees.
Note
Sites that include a fence line that abuts the primary perimeter
fence can be vulnerable to climb over intrusions where the two
fences meet. To increase security in this situation, extend the
FlexPS zone for at least 2 m onto the abutting fence.
