Active built-in system

An active built-in system also called anti-radar system is an active device that is designed to suppress or jam the laser signal emitted by a police device to measure the speed of vehicles, hence the term "laser jammer". Due to their active intervention in police measurement, their use is not legal. Although the name does not indicate this, the term anti-radar is most often used for devices that are intended to counter laser speed measurement, not radars.

Radar detector

A passive radar detector works differently than an active anti-radar. Instead of interfering with the emmited signals, it merely detects and alerts the driver to the presence of a radar. These devices work on the principle of the Doppler effect and intercept microwave police radars. Passive radar detectors do not interfere with police speed measurement and are therefore legal in some countries, they only detect and signal the presence of a radar, so the driver can reduce speed and thus avoid a fine for exceeding the speed limit. They are most often found in a portable form, placed on the windshield. A typical example is the GENEVO MAX detector. You can find out more about how a radar detector works here.

Portable radar detectors GENEVO


GENEVO MAX is our most powerful passive radar detector among portable devices. Thanks to many innovative functions and a completely redesigned laser sensor, together with a GPS database of the entire Europe, nothing will surprise you on the roads. GENEVO MAX offers a top level detections of most radars known in Europe, a market leading false alert filtering and therefore it is safely the best radar detector on the market among portable detectors. Lifetime database and firmware updates are included in the price of the detector.

GENEVO ONE M is the first and at the same time the smallest radar detector from the GENEVO family, which is capable of detecting previously undetectable MultaRadars and GATSO radars used in some European countries. Thanks to its compact dimensions and simple operation, it is a popular travel companion for European drivers. The detector also comes with free lifetime database updates.

Advantages and disadvantages of a portable radar detector


+ Legal in some countries (Including the UK)

+ It easily plugs into the car and works immediately

+ Compact and practical, can be immediately removed and used in another vehicle

+ Quality protection against most of the speed measurements


- It is located in the cabin and does not work behind metal coated windshields

- Does not reliably protect against laser measurement

- Attracts thieves and should therefore be removed after parking

- Its use is not legal in some countries

For what kind of vehicles are radar detectors suitable?

Almost any! Our most frequent customers are ordinary drivers with completely ordinary cars such as Škoda, VW, etc. Just pay attention to whether your car is equipped with metal coated windshield, which makes the use of a portable detector impossible. For powerful, luxury and sports cars, we recommend considering a built-in system on which we will be happy to prepare an quote for you.
