RF awareness around a protected boundary
RF perimeter protection focuses on radio activity near a facility, test range, border area, vehicle depot or temporary security zone. The hardware path normally starts at directional or sector antennas, then moves through low-loss cabling, protection or switching, receiver modules and detection electronics so operators can observe activity by direction, band and signal behavior.
Engineering boundary
The page is about RF sensing around a perimeter, not general video security or access control. Useful RF data depends on antenna pattern, placement height, cable loss, receiver dynamic range, scan bandwidth, unwanted-signal rejection and the repeatability of the monitored path over time.
Treat spectrum monitoring as an evidence chain

Separate continuous occupancy, intermittent interferers, short bursts, technical compliance checks and event capture because each needs a different relationship among instantaneous bandwidth, frequency resolution, dwel...

Spectrum Monitoring Receiver Front Ends: Dynamic Range, Scan Coverage and Verification
Specify a spectrum-monitoring receiver from antenna coverage to recorded evidence by balancing weak-signal sensitivity, strong-signal tolerance, preselection, instantaneous bandwidth, RBW, dwell, revisit time, thresholds, timing and calibration.
