A laser jammer sends a signal that confuses light detection and range (LIDAR) guns used by law enforcement to monitor vehicle speeds. It is not illegal in all areas, but some countries and regions have banned its use. The jammer detects incoming signals from a LIDAR gun and sends the appropriate signal to shut down the gun’s effectiveness. Some US states have passed laws to ban the use of laser jammers.
A laser jammer is a device typically used by motorists in an effort to counter the use of light detection and range (LIDAR) guns often used by law enforcement agencies to monitor vehicle speeds. These devices essentially work by sending a signal that confuses the return signal for a LIDAR gun, thus rendering the gun unable to correctly determine vehicle speed. A laser jammer is not necessarily illegal for use by motorists in all areas, although some countries and regions have banned its use.
Also called a laser scrambler, a laser jammer sends a signal that interrupts the use of a LIDAR gun. LIDAR guns are used by many law enforcement departments and allow police officers to quickly and easily determine how fast a vehicle is traveling. These guns work similar to radar, hence the name, and send out a pulse of light that is scattered by a vehicle. The gun firmware uses the time it takes for the signal to roll back to determine how fast the vehicle is traveling.
A laser jammer sends out a light signal that effectively confuses the firmware in the gun, which makes it unable to calculate and display velocity correctly. This can be done in many different ways, although the most effective method involves a laser jammer that detects incoming signals from a LIDAR gun. Once the signal is detected, the laser jammer sends the appropriate signal to shut down the gun’s effectiveness, notifying the driver of the vehicle that it has been targeted by a LIDAR gun. The sensor for this type of jammer is most often mounted on the front of a vehicle, although some devices may also be mounted on the rear or both front and rear.
The use of a laser jammer is not necessarily illegal in all areas, although some regions have passed laws to prohibit the use of such devices. While many countries have laws prohibiting the use of radar jammers to disrupt the use of older radar speed guns, these laws do not necessarily cover the use of laser jammers. In the United States, individual states have begun passing laws to ban the use of a laser jammer. This means that anyone who drives interstate and uses such a jammer should be aware of the legality of using such a device in each state.
