Revolutionary Pool Security and Safety

Developed by RJE International, the patented sonar-based SonarGuard^® system represents a revolutionary approach to swimming pool surveillance and safety. Its unique state-of-the-art technology is designed to alert parents and caregivers of a potential drowning by creating an invisible, ever-present underwater “sonar net”. When a child falls into the pool the sonar net is “broken” immediately triggering a loud, distinct emergency signal to alert parents or guardians.

It is the only “intelligent” system that is “on” 24/7 and able to immediately detect a small child falling, slipping, or sliding into a pool or spa while being able to screen out traditional causes of “false alarms” such as wind, rain or other surface disturbances (e.g., dog drinking water, ball or toys falling into the pool, etc.).

SonarGuard^® represents the only reliable and “invisible” 24/7 solution for the current and potential pool owner. We consider it the "last layer of defense" for pool safety.
