RADAR DETECTOR – A DEVICE THAT MAKES DRIVING SAFER

A word or two about “antiradar detector.” How it all works.

It is no secret that almost all police officers use a so-called device in their work – radar, which can determine the speed of the car quite accurately.

However, many motorists do not like it – speeding is punishable by a very imposing fine, and to prove the violation is quite simple – radar fixes everything. To prevent such cases, motorists buy and install an interesting device – antiradar.

What is the essence of antiradar? In fact, the antiradar can not be called a device – it is a radar detector. The fact is that there are two types of such devices:

  • active – that is, antiradar – it prevents the police radar from measuring your speed;
  • and the passive radar detector, it just warns you when you approach the radar.

It’s worth considering that antiradar, i.e. active devices, are prohibited for use by ordinary drivers around the world and their use is punishable. But ordinary radar detectors are quite common among car enthusiasts.

But ordinary radar detectors are very common among drives.

The principle of radar-detector The principle of radar-detector is very simple. It is known that the police author-darts emit high-frequency radiation, which is reflected from the approaching car, quite accurately captures its speed.

But the radar-detector registers this radiation much earlier and signals about it to the driver. In fact, ordinary radars can measure the speed of the car at a distance of 1-1.5 km, but you can register the waves they emit at a distance of up to 5 km! In other words, the radar detector informs you about the danger long before the police radar. When buying antiradar, pay special attention to the technical characteristics of the device – the range and number of false alarms. Some companies produce antiradars with auto-tuning – they can automatically determine the maximum range, and if desired, the driver can do it in manual mode as well.

Modern anti-radar systems can detect up to 99 percent of road traffic radars.

Currently, there are many anti-radar and radar detectors, which are equipped with quite good functionality – flexible sensitivity adjustment, display for displaying some information, for example, the range to the radar, etc.


Radar detectors can significantly reduce the cost of paying speeding fines. However, having a radar detector, otherwise known as an anti-radar detector, can not only reduce costs but also avoid many accidents. Having this device in your car allows you to be more vigilant on the road. You become aware that the police are working in your area, so drivers who have antiradar detectors monitor the road more closely. In a way, these devices are a constant reminder of the need to be safer on the road.

Nowadays there are quite a few automatic police radars on the streets of the city, which have learned to recognize traffic violations (speeding, passing at traffic lights, crossing solid line markings, etc.) and then send a fine. The radar detector is able to recognize such radars in advance and warn the driver if they are there. This makes it possible to reduce speed or take other measures. However, only quality devices will be able to recognize and warn of all types of police radars.

A good device is able to filter out false signals from radars used in airports, alarm systems, etc. But its cost will be a bit higher than conventional detectors, but there is no need to save on quality. To make the right choice and not to overpay for extra features, carefully read the feedback on antiradar left by users on the Internet, make a comparative review of several devices you like and only then go to the store for a purchase.

You should also make sure that the radar detector is able to recognize several frequency bands – X, K, Ka and laser speed meters. The X-band is a common source of false alarms, as this frequency is used by alarm systems in shops and banks, so by selecting the “city” option in the radar detector you can limit most of the false alarms. The X frequency is not widely used by police except in small towns that cannot afford new equipment.

Some modern models of radar detectors have a built-in GPS receiver, which allows you to connect the device to your computer and download the physical location on the map of installed police radars, which are marked by other car owners on the Internet. The built-in GPS will tell you when you approach one of these points.

Radar detectors are becoming more and more popular among car owners, who care about their safety and security of their finances.
