Abstract: A solar powered perimeter beam security system comprising a plurality of spaced towers. The towers have detection beams extending between them for detecting an intruder when at least one of the detection beams is interrupted. Each of the towers communicates with a remote unit. At least one of the towers is movable from one location to another. An alarm. The detection beams define an intruder detection area into which an intruder cannot pass without breaking at least one of the detection beams thereby setting off the alarm. The detection area is expandable and decreasable by moving at least one of the towers. The towers are incapable of movement without setting off the alarm once positioned with the detections beams being activated.

Abstract: A security system employs a plurality of towers for detecting an intruder. A detection beam extends between adjacent towers, and a breach in the detection beam detects the presence of intruders. The solar tower includes a solar panel, a solar mounting bracket, a swivel clamp, a swivel solar bracket, a solar cap opening mechanism, a solar base cap, and a top plate. The solar tower further includes a base unit, frame support rods extending from the base unit, a frame unit having face shield slots, and opposing face shields mounted in the face shield slots. The top plate is secured to the frame support rods with suitable fasteners.

Abstract: A security system employs solar towers for detecting an intruder. The security system includes a receiver/processor and transmitter for communicating with electronic devices in the solar beam towers, the receiver/processor and transmitter having an antenna, a housing and an indicator. The indicator includes information on the location of an intrusion. A detection beam extending between adjacent towers is used to detect intruders. The detection beam can include infrared, laser, microwave, and visible light. The alarms sent out by the system can include devices such as visual alarms, audible alarms, telephone dialers, and printers. The central unit exchanges information between the remote units via two way half-duplex radio. The system is a radio data reporting system, which reports events and selectively transmits an alarm. The alarm is transmitted to the central unit when a new event is detected, and it is displayed there.
