The Best Information on Radar Detectors

RadarDetectorsBest.com bring to you information on radar detectors, tips on buying one, reviews and more. Here, you can find all you ever wanted to know about radar detectors! To start with, let us first find out what a radar detector is? This is an electronic piece of equipment used by motorists to determine if their speed is being observed or supervised. The term originates from early speed-detection technologies, in which police bounced a radio wave off a moving vehicle with a device called a radar gun that determined the vehicle's speed by the Doppler-effect-moderated change in the wave's frequency. Most of today's radar detectors detect signals across a variety of wavelength bands – usually X, K and Ka and Ku. Now there is new speed-detection technology which uses pulsed laser light (LIDAR, commonly referred to as laser detection) rather than radio waves.

Modern "Radar Detectors" have been adapted to suit that technology, by detecting the infrared light emitted by these new detection methods. LIDAR detection is not nearly as reliable as the detection of radar, since the light is much more focused and often aimed below the windscreen level, where the detector is usually mounted. One must be careful as there are many options available these days which claim to absorb radar. But the truth is that most of these devices do not work at all, and if they do, it is by emitting an active radar scrambling pulse, which makes the device illegal to operate under in many jurisdictions.
