An alarm system surrounds a pool, or other body of water, to alert a parent or other personnel of a potential drowning situation for a child. A pad borders the pool and is separated into sections. The pad encloses pressure sensors that detect when a child comes onto the pad. The different sections include different sensors. The sensors are coupled to a detector device that determines different actions to perform to alert someone of the danger situation. The actions includes an audible alarm, vibration, shock or sending an image, video or message indicating that a child is in danger.
