Legal Laser Detectors in Hungary

The new traffic laws, which came into force on 1st September 2012, state:

„"Preventing, disturbing and altering the results of traffic control is forbidden, excluding the usage of speed radar detecting devices."

Therefore, the usage of radar and laser detector devices is not forbidden. Laser Detectors can detect the radars from a large distance (hundreds of meters), therefore we will be able to adjust the speed of our vehicle in time. These devices will be legal after the 1st of September as well, because they do not prevent or disturb the traffic control.

These detectors - no matter whether they are front or rear devices - can detect the signals (infrared light or radio-wave, used by speed radars), which are reflected from the back of the car ahead, therefore they can warn us that traffic control is in progress. The better the devices' sensitivity, the greater the chance to detect the radar in time and adjust our speed!



KIYO TECHNOLOGY Laser Detector built in license plate


In the beginning of 2014, KIYO TECHNOLOGY gave out it's most recent product, which had been optimized for the Hungarian market and is called KIYO D. This Intelligent Parking Assist system can be installed into the frame of a license plate, in addition it watches the same frequency as Hungarian laser-based radars do, therefore it can be used as an integrated stealth laser detector as well. Because this product had been optimized primarily for the Hungarian market, it's sensitivity exceeds other similar products on the market!


For whom detection of laser-based radars is not enough and wish to have an active protection, we can recommend our Laser Jammer Devices, or our Radar Detectors for detecting ordinary radars.



Useful information about Laser Radars

The technology of police speed measurement can be categorized into 3 groups: the laser-based technology, the radar-based technology and other speed radars.


The laser jammer devices disrupt the operation of the laser-based speedtraps, but are unable to detect or jam the radar-based or other speedtraps. Laser-based speedtraps may occur next to the driver's seat, in police and civilian vehicles as well. These devices can be mounted to a three-legged stand or can be held in hand. Furthermore, they can be operated manually or automatically, and can be used from a standing or a moving car as well.



The basic idea of the laser-based radars is the measurement of the spread and the reflection of the laser light. The name LIDAR (LIght Detection And Ranging) is connected to this feature.

The laser-based speedtraps are much more complex than their ordinary radar-based counterparts. These can measure speed 200 times/second, therefore their accuracy is far greater.

These type of speedtraps emit series of controlled, invisible infrared light beam pulses, in a straight line. The wavelength of the laser signal is 904 nm, but the frequency on which they work differ from device to device. The emitted signals are reflected from the moving car and by knowing the laser signal's spreading speed, the device can determine the speed of the vehicle.


The diameter of the light beam grows conically depending on the distance (for example, in the case of the PRO LASER III device, at a 300m distance, the diameter is 0,9m). The number of the emitted light beam pulses differ from device to device, therefore we recommend laser detector devices, which know all the frequencies that are being used. The most efficient detectors can detect the pulses from the start, therefore we will be able to slow the vehicle down.

Incidence of speed radars

The most often used laser radar brands in Hungary are: FÁMA, SCS and ARH. The most recent Hungarian model of laser radars is the ARH CAM-S1, which is in service from 26th March 2015. On Hungarian highways, the most common type is the stationary RAMET radar.

The new ARH CAM-S1 laser based radar has been deployed in the first wave of the VÉDA Camera Network for Intelligent Traffic Surveillance project. The purpose of the device is to check the traffic more efficiently. The device is much more advanced then it's predecessors; it not only can measure the speed of the vehicles more accurately, but also can document the different traffic offenses, such as crossing at the red traffic signal, violating the no entry sign, or driving in bus lane or in the emergency stopping lane.

In the past, radar- and laser detectors placed in the windscreen seemed an obvious solution to avoid radars. However, the new ARH CAM-S1 radar operates from a shorter distance and in a narrower angle, therefore the signal does not reach the height of the windscreen, where the detector is located.



The detectors located in the windscreen are perfect for detecting the ordinary radars and the older-generation laser-based devices, but to defend ourselves against the latest laser radars (which operate from a shorter distance and in a narrower angle), we should supplement our defense with a Laser Detector or with a Laser Jammer that can be build into the frame of a license plate.
