The Whistler Group was an electronics company based in Bentonville, Arkansas, [1] best known for its radar detectors. Whistler also manufactured power inverters , GPS navigation devices , inspection cameras, LED flashlights , vehicle dashboard cameras , and scanner radios . [ 2 ]
Police radio is a radio system used by police and other law enforcement agencies to communicate with one another. Police radio systems almost always use two-way radio systems to allow for communications between police officers and dispatchers .
While radar's radio waves can expand to 85 feet (26 m) across at 1,000 feet (300 m) from their source, LIDAR's light beam diffuses to only about 6 feet (1.8 m). [ citation needed ] A police officer targeting a car will most likely aim for the center mass or headlight of the vehicle and, because radar detectors are mounted on the windshield away ...
R8 Radar/Laser Detector. The R8 is Uniden's top-of-the-line offering. It can identify threats coming from all four directions thanks to its dual antenna, and you get notified via voice alerts.
An Icom IC-R5 hand-held scanner A GMRS radio that also has scanning capabilities. A scanner (also referred to as a radio scanner) is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases.

where is the speed of light, is the emitted frequency of the radio waves, and is the difference in frequency between the radio waves that are emitted and those received back by the gun. This equation holds precisely only when object speeds are low compared to that of light, but in everyday situations, this is the case and the velocity of an ...
A trunked radio system is an advanced alternative in which the channel selection process is done automatically, so as to avoid channel conflicts and maintain frequency efficiency across multiple talkgroups. This process is handled by what is essentially a central radio traffic controller, a function automatically handled by a computer system.
