1. laser intrusion detection system, said system comprising:
- a pool having a peripheral wall, said peripheral wall having a top edge;
a motion detection apparatus being mounted on said peripheral wall of said pool, said motion detection apparatus being operationally coupled to a power source and an alarm device, said alarm device being adapted to produce a sound, said motion detecting apparatus comprising;
a laser light emitting device for sending out pulses of emitted light, said emitted light generally comprising infrared light, said emitted light being comprised of a focused beam such that said emitted light can travel a distance with negligible dispersion of said emitted light;
a light detecting device operationally coupled to said laser light emitting device, said light detecting device being adapted to time said emitted light after said emitted light travels about said pool, said light detecting device being adapted to detect infrared light; and
a reflecting means for reflecting said emitted light about said pool, said reflecting means being fixedly mounted to said peripheral wall, said reflecting means extending about said peripheral wall, said reflecting means being generally positioned adjacent to said top edge of said peripheral wall.

Abstract
A laser intrusion system for detecting motion in a swimming pool for detecting a person entering a swimming pool. The laser intrusion system for detecting motion in a swimming pool includes a swimming pool. The swimming pool has a peripheral wall. The peripheral wall has a top edge. A motion detection apparatus is mounted in the peripheral wall of the pool such that emitted light travels over water in the pool. The motion detection apparatus is operationally coupled to a power source and an alarm device. The alarm device is adapted to produce a sound.
