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.

367/136 ; 377/39
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.
