Talking about a passive radar detector, such device does not work as a transmitter and in no way interferes or blocks the functions of speed measuring devices. It simply detects the presence of measuring devices and alerts the driver to ongoing speed checks.

Let's explain in detail how GENEVO radar detectors work and what makes their detection work in the real world.

A GENEVO radar detector combines two functions:

  • Detection of microwave radars in your area
  • GPS module combined with a database of points where non-detectable speed measuring devices currently occur

Detection of microwave radars

A Car radar detector is basically a radio receiver. Using an extremely sensitive antenna that scans its surroundings and searches for specific frequencies. When this frequency is detected the device alerts the driver.

However, there is a small catch, microwave signals are transmitted by various sources alongside the roads, eg. automatic doors at gas stations or adaptive cruise control systems, not only by law enforcement radars. Those false alerts need to be precisely identified and filtered.

For successful radar detection of those signals there are specific antennas, so do not hesitate to contact us for help choosing a system, or compare the GENEVO models.

The GENEVO MAX and GENEVO PRO II detect K and Ka band radar, plus MultaRadar CD/CT and Gatso RT3/RT4 photo enforcement radar used in parts of Canada and in some US cities. K, Ka and MultaRadar filters reduce false alerts. Fewer false alerts, less stress.

GPS module combined with a database

GENEVO detectors also have a GPS module with a database of fixed speed cameras, red-light cameras, average speed cameras and dangerous spots in the US and Canada. Many of these cameras do not use radar that a detector can pick up, so the database of their locations warns you instead. We build it from many sources, including news, social networks, users, testers and SCDB.info, and update it every month.

Depending on your settings, you are warned 820, 1,150 or 1,480 feet in advance. All you need to do is download the monthly update.

Detection range, false alert filtering, firmware updates and monthly database updates make GENEVO detectors reliable companions for everyday driving.

And that's it, now you know how a radar detector basically works and that it is a sophisticated device combining numerous functions for radar and camera alerts.
