  • Patent number: 5483224
    Abstract: A security system and method for monitoring security in the vicinity of a location perimeter is provided. The security system includes security sensors positioned in a detecting relation to the location perimeter for detecting a condition indicating a potential violation of security in the vicinity of the perimeter. The security sensors have a normal, negative state indicative of no violation of security and a positive state indicative of a potential violation of security. A detection indicator operatively communicates with the security sensors for storing information indicating whether a security sensor is in the positive or negative state. A signal receiver operatively communicates with the detection indicator. A signal transmitter is activated from outside the location perimeter, and transmits a control signal to the signal receiver.
