Along with a pool barrier and swimming instruction for your child, a pool alarm is an essential component of any pool safety plan. Be prepared and armed with the PoolEye Immersion Pool Alarm. Featuring the most accurate pool intrusion technology on the market for aboveground pools, you can rely on PoolEye for that added layer of pool protection. Plus, this battery-operated water motion detector is easy to install. It only takes about 10 minutes! The pool safety alarm features sub-surface wave detection, so there are fewer false alarms. Under water, the rudder switch inside the protective cage floats vertically, undisturbed by wind or rain on the surface. When an object enters the water and creates water movement, the rudder switch is moved off center and triggers the alarm. The 85 dB siren alerts when an object as light as 15 lb/7 kg is detected. This is a poolside alarm – the siren only sounds out of the main device. PoolEye is the only brand you need to give your family peace of mind when it comes to pool safety. Our affordable and accurate sub-surface wave detection alarms are third party tested for reliable performance. This water motion pool alarm is ideal for aboveground pools that measure up to 24’ round or 16’ x 32’.
