A radar detector is a type of detector radar characterized because it detects the frequencies of the cinemometros of the police as if outside a radio receiver. Radar detector is only effective with radar technology-based radars but not with radars based on cameras, bands of induction or laser technology radars radars, because either it can not detect its presence or do when it is already too late, when the measurement of speed has already been completed. Concepts of radar detector expression is a generic term that is often used as a synonym for radar detector to refer to any device that warns of the presence of a chronograph. There are three types of advertisers of radar: radar GPS locator: report of the closeness of a fixed radar based on GPS and base data of known fixed radars. Radar detector: detects the frequencies of the cinemometros. Radar (jammer) inhibitor: emit a powerful signal that inhibits the of the chronograph, preventing their proper operation. In the same way, the term radar is a generic name that encompasses all systems to control speed (cinemometros), exist four types: radar technology radars: are used both in fixed radars as mobile phones. Technology laser radars: are used only in fixed radars.
Induction bands radars: are placed under the asphalt. Radar based cameras: as radars stretch or monitoring by video camera. Radar detector radar detector efficiency is only effective with the radars of radar technology, since in other types of cinemometros or not you can detect his presence (ASRs based on cameras) or when it has done already too late since the measurement of speed has already been completed (laser and radar bands of induction technology radars). To improve the effectiveness of the radar detector, most incorporate radar GPS Locator, so that they not only alert when they detect an active radar but also the presence of radars fixed thanks to the GPS and the database of fixed speed cams. Legality of the legality of the radar detector radar detector varies widely from country to country: in some countries they are legal because they do not interfere with the proper functioning of traffic monitoring systems. In other countries they are illegal, since they allow you to circumvent the surveillance.
In other countries they are unambiguous or indefinite situation, for lack of a legislation needed in this regard. In addition, must bear in mind that in many countries can be illegal not only to use a radar detector but the simple fact of bringing it installed, which can lead to the immobilization of the vehicle. Therefore, we should always check the applicable legislation before use and acquisition. Source: Radar Detector
