Security system 100 employs solar towers 120 for detecting an intruder 28. The security system 100 includes a receiver/processor and transmitter unit 20 communicating with electronic devices in the solar beam towers 120, the receiver/processor and transmitter unit 20 having an antenna 22, housing 24, and an indicator 26. In specific versions of the security system 100, the receiver/processor and transmitter unit 20 may be a single unit (such as a transponder) having an antenna 22, housing 24 and an indicator 26. In other versions, the receiver unit and processor unit and transmitter unit are separate, each operatively connected to an antenna 22 and an indicator 26. The indicator 26 includes information on the location of an intrusion. |
