Best Police Radar Detector

It is not surprising that when you see a red and blue light vehicle chasing after you, the most common reason for this is speed violation on the road.

A radar detector (or police radar detector) is a device that alerts you about the presence of radar or laser ahead on the road so that you can slow down your vehicle's speed and ride in a disciplined manner. A radar detector device alerts you when the police radar gun is enabled on the road. It warns you through voice or message (if you have connected your smartphone) to slow down the vehicle's speed and helps you avoid unwanted tickets.

A suitable radar detector device helps and prevents you from paying dearly for any carelessness while driving on the road. To avoid unnecessary expenditure of your money and an accident, you should put to accurate, fast-responding suitable radar detector device in your vehicle.

What is a radar detector device, and how it works?

A radar detector is a vehicle (car) device just like a portable GPS or speed camera. It is specially designed to alerts about the presence of speed detector hardware ahead on the road. Traffic police uses radar guns (devices) to detect driver's speeds at a certain distance. A radar gun works on specific radio waves, and a radar detector warns you the presence of radio waves near it.

Some points to remember before starting shopping radar detector

Selecting a proper radar detector is not an easy task, as it comes in various price ranges with different functionality and accuracy. They are available in various models in the market and also not so cheap. While purchasing a radar detector, you should keep in mind that you are getting what you are paying for in terms of the device's functionality and accuracy.

It might be possible that cheaper radar detector models to be less accurate and false radar readings. On the other hand, top-range and expensive models can offer GPS functionality, and contains intelligent technologies that can identify unwanted radar signals. These unwanted signals may be from other sensor devices that use similar radio waves.

Due to growth in the technology and radar detector's popularity, some traffic police also use a secondary device that detects the vehicles containing radar detectors. This article will discuss some of the best police radar detector devices that are undetectable and avoid unwanted attention.

Some standard radar detector terms that you should know:

DSP: It is a short form of digital signal processing, which usually uses a microchip to automatically identify and gives priority to the radar band used by law administration.

K-Band: It is a common radio frequency emitted from a hand-grip radar gun that operates between 24.05 and 24.25 GHz.

Ka-Band: It is one of the most popular frequencies used by most police to detect vehicle speed; it operates between 33.4 and 36.0GHz.

Laser: It is used to catch speeders; many traffic police have switched from radar to laser signal. Laser guns are more sensitive and work accurately to detect a vehicle's location and speed.

Laser defuser: It is an electronic device that detects the presence of police radars and jams the signal emitted by laser guns. However, the use of laser jammer devices is illegal in some countries.

X-Band: It is a segment of high radio frequency which operates between 5.2GHZ to 10.9 GHz. It is mainly used for traffic radar sensors and automatic supermarket doors. It is one of the most accessible bands to detect high-speed vehicles on the road.

Some important points related to radar detector

How far can police radar detect your vehicle speed?

Police radar's speed detection range depends on vehicle shape and size. For example, police radar could detect a full-size truck speed from a mile away, but a small-size car bounces such a week signal. Police radar detects small car's speed within the range of 500 feet from radar.

Where should you place a radar detector?

Try to keep your radar detector in a place where it cannot come under surveillance. You can place it as close to the rearview mirror as below or above it. Place your detector in a place where others have less visible.

Are radar detectors worth it?

If you mostly travel by car, then a good radar detector becomes useful. You can recover the cost of a radar detector if it alerts you before a cop catches you and if you will be safe from ticket cutting on the road.

What is a radar jammer?

A radar jammer is an electronic device that detects police laser beams. It transmits interfering radio frequency signals towards the radar gun and interferes in radar operation. It confuses the laser gun and returns false information to the gun.
