The VTR2 series of high power strobe lights from Gardasoft can be used for automatic number plate recognition and other traffic applications. These include classification of vehicles based on their type (car, lorry, motorcycle, etc.) or vehicle brand using software from STEMMER IMAGING

The VTR2 range of line LEDs provides an efficient, stable high brightness strobe source with a fast repetition rate for high camera frame rates. The lights can strobe in free running mode, or they can accept an external trigger signal to synchronise the light with a camera. Available in a range of infrared wavelengths (740nm, 850nm and 940nm) and white light (for use with colour cameras), together with a choice of beam angles, the lights can be configured to meet the spectral needs of the imaging system as well as the field of view.

Housed in a weather-proof enclosure rated to IP66, the VTR2 is capable of illuminating complete vehicles. The high brightness output makes the lights ideally suited to traffic applications where the distance of the vehicle from the optical system is increasing and allows for more information to be gained from the image rather than just the vehicle number plate.
A serial interface provides access both to the light settings such as the light temperature and to a diagnostic capability in the unlikely event of an LED failure. Since the thermal management of the LEDs is critical to long service life, the VTR lights have an internal temperature limit and will automatically shutdown if this is exceeded. All settings are stored in non-volatile memory.
