Reverse flash systems and laser jammers against fines and driving bans? Can you really escape the speed trap and the laser with it? Mostly not! So-called counter-flash systems have long been used by vehicle drivers to avoid unwelcome traffic tickets and not to fall into the radar trap. Inconspicuous in their appearance, they can usually be easily attached to the windshield without being recognized immediately. If a driver falls into a speed trap, the counter-flash system ensures that the authorities can no longer see his face. At least that's the theory. The system outshines the face of the driver, with the aim of avoiding traffic tickets or fines. Unlike conventional radar detectorsAccording to the providers, counter-flash systems can also be used in front of speed measurements by means of a light barrier protect and make the face unrecognizable. But how exactly do reverse flash systems work?

Counter flash systems / laser jammers

Who is only interested in very specific areas around the topic "Rear flash systems, speed camera jammers & Co." iIf you are interested, you can use the following jump labels to navigate directly to the desired topic with just one click. And you can get back to this overview just as quickly with just one click from the selected menu item. However, we recommend our readers to always read the entire article. Some points are only really comprehensible and understandable when the complete information article has been read.

If the driver falls into the speed trap, the reverse flasher emits a bright light that dazzles the cameras. The way it works is based on a principle that is also known to photographers: the flashlight, which is sent out by the speed camera, uses a photo cell to send the signal to a second device, also to flash. This means that instead of a face, only a bright light can be seen on speeding tickets. Due to the extremely short exposure time of up to a 750th of a second of the official speed cameras, commercial "slave speed cameras" from the photo shop are, however save Alternative to real counter flash systems. The same problem exists with counter flash systems of the first generations. They are expensive and very unreliable. are the most reliable the latest devices. With the new devices, the police can still recognize the type of vehicle, the time of the crime, the speed measurement and even the license plate number, but the image of the driver is denied. Due to the fact that the driver of the vehicle cannot be identified, an essential piece of evidence is missing.

The counter-flash system is quickly confiscated!

But for all users of counter flash systems: care should be taken when using it. Law enforcement officers are typically trained to recognize, identify, and immobilize such devices. During general traffic checks, it can always happen that users of counter-flash systems are caught red-handed. In an emergency, public prosecutors could even classify the attempted hiding of the number plate as forgery of documents, and high penalties would result. And also the "blinding" of the face protects not one hundred percent before a penalty. If the driver is outside of the light beam, it can happen that only parts of the face are unrecognizable and the person can still be identified. Counter-flash systems therefore offer complete protection not, especially when an unobtrusive pursuit by means of the police video trolley occurs or a police patrol waits just a few meters behind the radar device and stops the vehicle. The use of a counter flash system can result in high penalties and even criminal penalties. "Back to overview

What you should know about older counter flashers!

These are rather smaller devices, which usually behind the interior mirror are attached and are intended to ensure that a counter-flash is triggered in the event of a photo flash. The intention behind this is that the registration photo overexposed and is therefore unusable. As great as this invention sounds, unfortunately it is useless. Usually, the photo facilities of the authorities are prepared or adjusted for strong backlighting, otherwise particularly bright headlights would make every picture unusable. Moreover, the counter-flash of the older devices delayed. By the time the oncoming flasher can react, the photo has usually already been taken. As mentioned above, the exposure times are usually between 1/500 and 1/750 seconds. And for all reverse flashers, including the new, faster devices, the following applies: even if the reverse flasher does its job and makes the person in the photo unrecognizable, the authorities still recognize the license plate number of the car and can thus determine the owner. It is not uncommon for the driver to be identified in this way, for example in the case of people living alone or driving alone. "Back to overview

The most important facts about laser jammers!

More and more traffic controls are being carried out with the help of lasers accomplished. So-called laser jammers (for example from ESO Guard) are devices that warn of laser guns and can often prevent detection by them. These devices are also installed inside the vehicle and usually have a sufficiently high transmission power and advance warning time so that the driver can adjust his speed accordingly. In addition, the warning is extremely discreet so that the car can be prevented from being recorded without the police or authorities noticing. The measurement is carried out on a good device without acoustic or visual warning cancelled. "Back to overview

As a rule, high-quality laser jammers behind the grille installed and cannot be recognized at first glance. Here are a few details about particularly high-quality devices:

they are suitable for vehicles with a curved front (including super sports cars)
they do not produce errors when using laser blinders
they are fully compatible with other laser jammers (laser blinders)
there are even sensors that fit into the license plate bracket
good devices do not trigger any error messages on the measuring device
they offer full protection against ESO one-sided sensors (also ESO 3.0)
they offer almost full protection against all ESO light barrier measurements
they also disrupt Autovelox systems in Italy and Spain
they have flexible sensors for installation
they have a tiny control unit
they have at least two sensors for protection from both sides

Jamming technology and laser jammers in the fight against speed cameras!

There are now a large number of jamming systems on the market that are intended to supplement a radar detector. Some of the most common include: laser blockers, ESO 3.0, photo blockers, and photocell jammers. They work like a cell phone blocker, a cell phone jammer or a cell phone jammer, but they do it not the mobile phone, but all devices for measuring speed were disturbed. During the brief moment in which the police are lasering, the pistol is disturbed with the help of jamming signals. If the so-called ESO ES 3.0 is used for measurement, while passing through the measurement range creates a disturbance. This disruption ensures that for a split second no measurement is possible. This type of disorder is particularly prevalent in areas where next to the Poliscan Speed procedure also Photocells used to measure speed is popular. For all other areas, normal radar and laser detectors already provide good protection. "Back to overview

How laser jammers work!

Laser jammers work by using a specific technique to warn of a measurement by the laser. This happens with the help of a tone, which the driver can hear shortly before the laser control. In addition, with the help of a signal emitted by the device the measuring process is disturbed. "Back to overview

Install radar detectors and laser jammers permanently!

Built-in radar detectors and laser jammers as protection against unpleasant penalties and feared fines sound tempting. Over time, the warning systems have become increasingly popular and can now be found in a large number of vehicles. But even these devices have their limitations. Due to their design, they cannot warn against many measuring systems and therefore do not offer sufficient protection against penalties and fines. But according to the manufacturer, there are still ways to protect yourself comprehensively from measuring systems. The devices that are supposed to make this possible are so-called Radar detectors, laser jammers, light barrier jammers and GPS speed camera warningsright These devices are also hidden and permanently installed in the car. According to the manufacturer, the best protection is provided by devices that perform all important tasks giving. So-called High-end radar warning systems are particularly interesting because they not only offer a high level of protection against penalties and fines, but can also be installed very discreetly.

The difference between radar and laser!

Radar

The measurement with the help of radar devices makes use of the so-called Doppler effect. The measuring device continuously emits radar waves at equal intervals. When a vehicle drives past, the car reflects the emitted radar waves back to the device. The smaller the distance that lies between them, the faster the car runs. Since the waves emitted by the radar device can be detected by the radar antennas from a great distance, a warning can be issued in good time and the speed can be reduced accordingly.

Laser

The technology behind the measurement using laser guns is also based on the reflection of radar waves. However, the measurement only takes place at the moment when the police officers decide to trigger the radar gun. This measurement takes place much faster and only at a certain, very short point in time, which is why there is no possibility of advance warning and subsequent adjustment of the speed. laser blocker However, they can interfere with this measurement by interfering with the signals emitted by the pistol.

Saving money with portable devices?

All those who want to save money will enjoy the easy to install cheap portable devices. Installation is easy and power is supplied via the conventional 12 volt plug in the car. As a rule, these devices are quite reliable, but they do have one shorter warning distance as built-in devices. However, with this type of device no laser protection available, in rare cases laser measurements can be detected, but an interference signal cannot be sent out. "Back to overview

Built-in radar detector!

Radar detectors help to avoid falling into the trap of radar devices and offer a high level of preventive protection. The devices are usually installed almost invisibly in the radiator grille, from where the radar radiation can be picked up particularly well. However, the devices only offer laser protection in combination with laser blockers. Without a laser blocker, the devices cost 600 to 1900 euros. The installation costs amount to 200 to 500 euros. "Back to overview

The laser blocker!

High-quality laser blockers permanently installed in the car offer a very high level of protection against laser measurements, according to the manufacturer even protection in 95% of cases. However, such devices can provide XNUMX% protection do not offer, because external factors can also have an influence. As a rule, two laser sensors are attached to the radiator grille. The price of this type of device ranges from 400 to 900 euros, the installation costs range from 200 to 500 euros. Radar detection is only possible with the installation of a radar detector.
