Abstract
In the present invention an intrusion detection system comprises a detection element configured to detect an intrusion in a location, and to transmit an intrusion signal upon detection of the intrusion. The system further comprises a monitoring device configured to capture images of the location upon the detection of the intrusion, and to transmit image signals representing the captured images. A single transmission line is in electrical communication with the detection element and the monitoring device, wherein the transmission line is configured to carry both the intrusion signals and the image signals.
Claims21
An intrusion detection system, comprising:
- a detection element configured to detect an intrusion into a location, and to transmit an intrusion signal upon detection of the intrusion;
- a monitoring device configured to capture images of the location upon the detection of the intrusion, and to transmit image signals representing the captured images;
- and
- a transmission line in electrical communication with the detection element and the monitoring device, the transmission line configured to carry the intrusion signals and the image signals.
A transmission system for use in an intrusion detection system, comprising:
- an electrical transmission line configured to be placed in simultaneous electrical communication with an intrusion detection element for detecting an intrusion, and an intrusion monitoring device for viewing details of the intrusion;
- and
- a combiner circuit in electrical communication with the electrical transmission line, the combiner circuit configured to combine an intrusion signal received from the detection element with image signals received from the monitoring device, so as to transmit a combined signal along the electrical transmission line.
A method of detecting an intrusion, comprising:
- generating an intrusion detection signal upon detecting an intrusion;
- transmitting the intrusion detection signal along an electrical transmission line;
- generating image signals corresponding to images of details of the intrusion;
- and
- transmitting the image signals along the electrical transmission line.
A unitary intrusion detection device comprising:
- a housing;
- a detection element, in said housing, configured to detect an intrusion into a location, and to transmit an intrusion signal upon detection of the intrusion;
- a monitoring device, in said housing, configured to capture images of the location upon the detection of the intrusion, and to transmit image signals representing the captured images;
- and
- an illumination element, in said housing, configured to illuminate the location.
