System and method for automatically detecting unauthorized entry into a pool

A method for automatically detecting unauthorized entry into a pool, comprising the steps of:

• controlling a plurality of light beam emitter devices to emit a plurality of light beams and controlling a plurality of light beam receiver devices to receive a plurality of emitted light beams, each of the plurality of light beam receiver device receiving a light beam from corresponding light beam emitter device;
• forming a grid of light beams extending across a surface of the pool, the plurality of light beam emitter devices being positioned along an interior perimeter of a pool and the plurality of light beam receiver devices being positioned along the interior perimeter of the pool, each of the plurality of light beam receiver devices facing each corresponding light beam emitter device;
• monitoring the lights beams of the grid;
• detecting unauthorized entry into the pool based on an interruption of the light beams of the grid;
• determining a level of the interruption of the light beams of the grid exceeds a predetermined threshold when a number of interrupted light beams of the grid exceeds a predetermined threshold of interrupted light beams;
• generating and transmitting an alarm message to at least one of a remote device, a home alarm system and a monitoring station when the number of interrupted light beams of the grid exceeds the predetermined threshold of interrupted light beams;
• and
• generating an audible alarm via a speaker proximate to the pool when the number of interrupted light beams of the grid exceeds the predetermined threshold of interrupted light beams.
