How Does A Car Warning Radar Operate?
The operation of the warning radar is based on GPS (Global Positioning System). The process is very simple: just download the list of radars locations and dangerous areas through a CD-ROM or the Internet and store it in the device. This list is compiled by the police.
A warning is triggered upon approaching these areas. The alarm does not detect the waves but uses data downloaded to warn the driver. A regular update is needed because the list changes constantly. Be careful when buying! Some manufacturers are charging their customers to upgrade without any other additional service. Do not hesitate to buy an alarm with free update. Acquisition time varies depending on the satellite models. This time determines the ability of the device to receive more or less quickly the GPS signal. Also check that the alarm works well with a thermal windshield which is used by most new cars.
