Radar detectors have been designed to give drivers some protection against erroneous radar readings and radar errors caused by poorly trained operators.
Radar detectors are essentially radios that are tuned to the exact microwave frequencies employed in traffic radar.

The detectors are connected to triggering electronics and a data-acquisition PC inside the building.
Mains powered detectors are also available which do not require a battery and are wired directly by an electrictian to an independant mains supply.

PIR detectors trip an alarm by sensing changes in infrared energy levels caused when an intruder moves about the protected area.
Most detectors are battery powered and can be installed with a screwdriver and drill and by following the manufacturer's instructions.
The detectors steel conductors have a high resistance per foot compared to the copper feed wires connecting the detector to the control panel.

Cryogenic detectors are set to be the future technology of choice for astronomy, offering single photon detection combined with high energy resolution and high quantum efficiency.
CDMSII detectors are designed with the primary functionality of detecting the minute phonon signals generated within a detector crystal by elastic collisions between detector nuclei and WIMPs.
Detectors tell physicists just what new particles have been formed from beam collisions.
