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).
