An intrusion prevention device running a program thereon and communicably connected to an external control device, the intrusion prevention device including a main body to removably connect to at least a portion of a building, a primary nozzle movably disposed on at least a portion of the main body, at least one sensor disposed on at least a portion of the main body to detect a presence of at least one hostile third party, such that the primary nozzle dispenses a lachrymatory agent toward the at least one hostile third party in response to a determination that a threat exists, a camera disposed on at least a portion of the main body to record the at least one hostile third party thereon using at least one of at least one picture and at least one video, a speaker disposed on at least a portion of the main body to emit at least one alarm sound in response to the determination that a threat exists, and at least one security light disposed on at least a portion of the main body to illuminate a surrounding area in response to the determination that a threat exists.

A system for the surveillance of terrain and the detection of intrusions over a plane extending into that terrain. A curtain array of light beams is projected along the plane and reflections from the terrain are detected by a sensor array essentially spatially coincident with the array of light sources. The times of flight of the beams are determined, and these characterize the form of the terrain being surveilled. The initial background reflection pattern is acquired and stored by the system. A sudden change in this detected background pattern can be defined as arising from an unexpected reflection, indicative of an intrusion. Signal processing systems are described utilizing modulated laser beams and detection at a frequency at least twice that of the modulation, such that reflected signals arising from the ON and the OFF periods of the laser modulation can be subtracted to eliminate the background signals.
