Stinger Freedom Laser (2x2) incl. TouchStrip



Laserjammer Stinger Freedom 2x2 incl. TouchStrip

The Stinger Freedom Laser (2x2) consists of two elements - four outdoor sensors (2x sender, 2x receiver) and a control unit. The sensors, which have now been further reduced compared to any other model on the market,

Stinger freedom lasers have special infrared lenses that recognize the measurement with the laser gun and react with the same pulse frequency depending on the detected laser gun. The laser gun will then not be able to display any measured value, since an evaluation of its own reflection radiation, which is now mixed with the radiation from the Laserguard diode.


The control and display unit contains a display and a loudspeaker. The TouchStrip indicates whether the system is ready for operation. In addition, the device now also offers USB update options. The Stinger Freedom Laser ("2x2")  is equipped with the smallest sensors in its performance class. Outstanding laser reception was achieved through carefully developed hardware and software of the receiving system, based on the manufacturer's patented innovations.

During the development of the system, the top objctive was perfect functionality paired with ultimate efficiency in all circumstances, improved filtering of sun interference and laser sources, improved resistance to temperature fluctuations and electromagnetic interference. Although the sensors have become smaller, the control unit has grown and offers new functions and extensions. The system can consist of up to 6 ("3x3") sensors.

The sensors are installed in the front of the vehicle and protect against laser measurements. Depending on the vehicle, 2 ("1x1") or more sensors may be required. 2 sensors are sufficient for a normal car. For a vehicle with a large front, such as an SUV, 4 ("2x2") sensors are necessary, for a trucks it may be even 6 sensors ("3x3").

When a laser gun is aimed at the vehicle, the system recognizes the type of laser measurement and reacts so that the measuring device cannot evaluate your laser reflections. An incorrect measurement is displayed on the laser measuring device. The operator will then try to measure again. He assumes that he has not aimed correctly or that the vehicle is reflecting poorly. The driver can now adjust the speed. After this is done, you should turn off the system. For safety reasons, the Freedom system is automatically switched off e.g. after 4 seconds (set by the user). For optimal function, the receiver should be mounted near the license plate, since the pistol is pointed at the vertical license plate in almost all cases. A recommendable place is in or behind the grille. The sensors should be horizontal and cleaned from time to time.

About speed measurements with radar ("speed trap")

The meter from the authorities can be installed in a vehicle or on a roadside tripod or fixed in a box. It controls the incoming traffic and is effective up to a distance of 40 m. The radar radiation hits the vehicle and is reflected. As the vehicle moves toward the meter, the frequency of the reflected radiation increases. The pace is calculated from this. If it is above the limit, a photo ("with flash") is triggered to capture license plates and drivers. The measured pace is shown in the photo. Radar measurements are used all over Europe, a real-time warning by a high-quality fixed radar detector is possible without any problems.

About speed measurements with laser ("laser gun")

With a laser measurement, the incoming and outgoing traffic can be checked up to about 300m away. The device is operated by hand or on a tripod. In the process, invisible light pulses are emitted that reflect the license plate number. From the duration of these pulses, the tempo is calculated. For a valid measurement, the license plate must be aimed with the help of a visor. If not all of the emitted signals are received again without interference, for example because of a heavily soiled car, the device automatically stops the measurement. This also applies if individual values ​​are outside the tolerance, for example due to blurring. Since no photo is taken during lasering, the vehicle must be stopped immediately after the measurement in order to log the driver and vehicle data in addition to the measured values. Laser measurements are used in Germany and are also very widespread across Europe. An ideal solution is the complete prevention of a measurement by using a laser jammer (e.g. Antilaser Priority Dual).

Speed measurements with single-sided sensor eso 3.0 ("light barrier")

In recent years, a new mobile measuring device has become popular, particularly in Germany: the so-called "single-sided sensor eso 3.0", which is sometimes referred to as light barrier measurement due to the previous generations. The measuring device eso 3.0 is distinctive due to its characteristic structure and can be easily recognized due to the large number of photos on the Internet. In principle, proven radar detectors and laser systems remain ineffective here since neither radar nor laser light waves are emitted by the measuring device. After no protection was possible for a long time, there is now a remedy in the form of the eso guard PRO, which is installed as a fixed installation solution on the license plate. 

About stationary speed measurements ("starter box")

The measuring device (also called "fixed speed camera" or "flash column") is permanently installed on the roadside. It controls the incoming traffic and is effective at a distance of 3-15m. In doing so, an induction loop triggers a signal in the road or, in the case of modern flashing columns, laser radiation hits the vehicle and is reflected. If the vehicle moves towards the measuring system, the light frequency of the reflected laser radiation increases. The pace is calculated from this. If it is above the limit, a photo ("with flash") is triggered to capture license plates and drivers. The measured pace is shown in the photo.
This method of measurement can be found everywhere in Europe, a timely warning by a radar detector with integrated GPS speed camera database is easily possible.

Speed measurements with follow-up video ("PROVIDA video car")

In a video tracking measurement, the measuring vehicle, which is often not recognizable as such, travels behind the car to be checked over a distance of at least 300 m. A video camera captures the monitored car, and a computer connected to the speedometer calculates the average speed on the track. There is a tolerance deduction of 5 km / h. This measurement method is used regularly on motorways in Germany, mostly it is vehicles of German brands of the middle and upper class.The warning and protection by radar detectors or laser interference is technically not possible. The Target Blueye does provide a warning based on TETRA technology (check your country whether TETRA is used in your country).
