Abstract
Apparatus in one example comprises first and second fence posts that cooperate to represent a subportion of a perimeter to be secured. The first fence post comprises a first motion sensor and a first laser sensor. The second fence post comprises a second motion sensor and a second laser sensor. Upon physical movement in a region outside the subportion of the perimeter, one or more of the first and second motion sensors serve to automatically perform a detection of the physical movement in the region outside the subportion of the perimeter. Upon the detection of the physical movement in the region outside the subportion of the perimeter the one or more of the first and second motion sensors serve to automatically cause the first and second laser sensors to monitor for physical movement at the subportion of the perimeter.
