Abstract
Described is a security sensor comprising two or more sub-sensors for use in a variety of installations where different magnetic fields may be experienced by the security sensor as a result of the variety of installations. One of the sub-sensors may have a low magnetic sensitivity while the other sub-sensor may have a much higher sensitivity to magnetic fields. In operation, one or both sub-sensors are used to determine if a door or a window has been opened.
Claims20
A near-far security sensor for monitoring a barrier, comprising:
- a first sub-sensor for detecting a magnetic field produced by a magnet associated with the barrier;
- a second sub-sensor for detecting the magnetic field produced by the magnet associated with the barrier;
- a transmitter;
- a memory for storing processor-executable instructions;
- and
- a processor coupled to the first sub-sensor, the second sub-sensor, the transmitter and the memory for executing the processor-executable instructions that cause the near-far sensor to:
- monitor, by the processor, the first sub-sensor and the second sub-sensor as the barrier is placed into a closed position;
- determine, by the processor, that the first sub-sensor has detected the magnetic field and that the second sub-sensor has not detected the magnetic field;
- and
- select, by the processor, the first sub-sensor for monitoring the barrier based on the first sub-sensor detecting the magnetic field.
