Smartpool Pooleye PE20 Pool Alarm for Inground Pool. If you have kids, pool safety is critical. A great way to prevent unsupervised swims or falls into the pool is to install a pool safety alarm. The line of pool alarms from PoolEye® for inground and aboveground pools uses subsurface wave detection to send an alert when an object as light as 15 pounds enters the water. That technology also allows it to ignore surface-level disruptions such as wind, rain and floating toys for a reliable signal every time. Keep your pool safe with an easy-to-use and unobtrusive pool barrier alarm from PoolEye.
