System and method for automatically detecting unauthorized entry into a pool

A system for automatically detecting unauthorized entry into a pool, comprising:

• a plurality of light beam emitter devices positioned about the pool;
• a plurality of light beam receiver devices positioned about the pool, each of the plurality of light beam receiver devices each corresponding to a light beam emitter device;
• and
• a processor in communication with the plurality of light beam emitter devices and the plurality of light beam receiver devices, the processor:
• controlling the plurality of light beam emitter devices to emit a plurality of light beams and controlling the plurality of light beam receiver devices to receive a plurality of emitted light beams to form a grid of variable sizes and widths extending across a surface of the pool, each of the plurality of light beam receiver device receiving a light beam from corresponding light beam emitter device;
• monitoring the grid;
• detecting unauthorized entry into the pool based on an interruption of the grid;
• determining whether a level of the interruption of the grid exceeds a predetermined threshold;
• and
• if the level of the interruption of the grid exceeds the predetermined threshold, generating and transmitting an alarm message to a remote device of a user;
• wherein the plurality of light beam emitter devices and receiver devices are mounted below the surface of the water.
