Casing-Pattern Detector

Each brief visit near a fence line or side window shows up as a short presence at a spot where people do not normally linger. Once means nothing. The same quiet spot, short stays, several days in a row — that pattern is the classic sign of a burglar scouting, and it is exactly what the system looks for.

In the physics: Each loitering event is an NLOS presence detection with an RTI location estimate; casing produces a statistically improbable spatio-temporal recurrence — repeated short dwells at the same low-traffic perimeter cell — that is distinguishable from postal workers and gardeners by dwell location, duration, and time-of-day distribution.
