A method for providing a security barrier proximate a body of water such as a lake or a swimming pool. One or more beams—preferably infra red light beams—define the barrier. A detector is positioned to monitor each beam so that a moving object “cutting” the beam can be detected by a controller in communication with the beam or beams. A motion detector monitors for motion in a broad area around the location of the security perimeter. The motion detector is also in communication with the controller. The controller deactivates the beams and relies solely on the motion detector when no objects are near the perimeter. Once the motion detector senses an object in the area of the perimeter, however, the controller activates the beams. If an object then interrupts a beam, the controller activates an alarm.
