If you install and use a radar detector in your vehicle, and it saves you from even one expensive speeding ticket, the detector can pay for itself. For drivers who spend a lot of time on the road, a well made detector can help them stay within the speed limit by reminding them when an actively scanning traffic cop is nearby.
A few facts about police speed sensors
Most highway patrol and police cars are equipped with some speed detector. The most common types are radar and lidar. Some folks erroneously refer to lidar as 'laser radar,' but the technology doesn't use any laser beam. Radar speed detectors employ microwaves, whereas a lidar sensor uses pulses of infrared light to determine the speed of a nearby car, truck, SUV or motorcycle. Accurate to plus or minus 1 mile per hour (± 1 MPH), these devices are a bit more accurate than moving mode radar sensors, notes CopRadar magazine.
The word radar is an acronym for Radio Detection and Ranging. A radar device utilizes a remote sensor to emit microwaves, electromagnetic waves or infrared light that measure reflections. Radar devices as used by traffic enforcement can detect location, motion, and speed. Radar may also include a proximity sensor as well as a field disturbance sensor. Doppler radar used by police departments can transmit and receive reflections simultaneously. Multiple sample periods may be needed to give an officer an accurate reading. The same may be required for longer-range targeted vehicles, or if the police radar device has just started operation.
Types of police radars
Police radar devices are available in 2 typical configurations; fix mounted or hand-held.
A hand-held radar gun may be used to measure the speed of approaching and receding traffic. Hand-held radar operates from a stationary position and can transmit continuously or on demand.
Fixed mount police radar works in both stationary and moving mode. This means that a police car that's driving on the highway near you can catch you speeding, especially if you do not have a proper radar detector in place. Likewise, an officer sitting on the side of the road can detect your speed with a fixed mount radar unit. Similar to a hand-held radar gun, a stationary mount device can transmit all the time or just when the officer tells it to detect speeds.
To hard-wire your radar detector
If you wish to do away with batteries, you can clip off the power jack and connect the white wire to ground and the red wire to a 12-volt source. For safety, always employ a 5 amp, fast-burning fuse. Find detailed instructions about hard-wiring your radar detector on our FAQ page.
