Intrusion Alarm Patents
© Brooke Clarke 2008
Background
There are numerous sensors that can be used to detect intrusion into a
protected space. The sensor and it's processing circuitry can be
optimized for this application and that's the subject of many patents.

Counts geophone zero crossings
where there is normally a high number, but when an intruder is present
there are fewer crossings. Frequency only.
This is very similar to the noise operated squelch circuit. When
a signal is present it quiets the noise.

Doppler
There are a number of frequencies used for doppler systems. Door
openers commonly use 10.5 GHz. Commercial volume protection
alarms may use 915 Mhz. Military systems may use a frequency
where the height of a man is 1/2 wavelength or about 72 MHz.
There have been some attempts at using ultrasonic audio in doppler
systems but they have not worked very well.
