Criminals frequently use cell phones to keep in touch with the driver/lookout
while committing crimes such as burglary. See example below.
Because most crime is committed by a small number of very frequent crime committers
(often heroin addicts), getting a conviction with maximum evidence, while avoiding
being a being a witness and giving testimony: this Radio Noise Recorder captures
unprocessed radio frequency noise within a broad range that covers cellphones,
wifi, bluetooth, automotive transmitters and other wireless signals that criminals
emanate.
The Recorder has no network connection and has no on board method of searching
and converting the noise to any kind of understandable signal. Ideally after
the crime the police would get a warrant from the court and then the post processing
could be done to identify they time and type of equipment sending signals' for
example make and model of car from tire pressure radio senders, cell phone from
wifi and bluetooth mac address, content of transmission where the court and
technology allows decoding such content.
antenna, enclosure, filtration, amplification, digitization of noise into amplitude
and frequency and time tagged units, recording to an SD card. erasing and over
recording new information over the oldest information. Possible external triggering
from motion detection etc. to save before,during and after triggering event.
