What is the difference between surface alarms and subsurface alarms?
Subsurface pool alarms mount onto the deck or the side of the pool and probe under the water to detect motion. All-Safe has determined the best brands of these types to be Aquaguard, Swim Alert, and Espio. Surface pool alarms float in the pool and detect motion on the water’s surface. All-Safe does not sell or endorse this type of pool alarm. PoolEye Pool Alarm and the Pool Patrol Pool Alarm, however, use this type technology.
Surface pool alarms float on the surface of the water. They have a higher rate of false alarms due to wind, rain, etc. Subsurface pool alarms attach to the side of the pool, and a portion of the sensor is submerged below the water’s surface. Because the alarm is submereged, there is a lower rate of false alarm.
