Test Drive ALPR+

Experience our powerful ALPR+ API that analyzes images and returns valuable license plate data (character string + region information) as well as vehicle information (make, model, generation and color). 

Unlike other solutions, Sighthound ALPR+ does not require license plate detection as a prerequisite for vehicle recognition. Treating both categories as independent allows Sighthound ALPR+ to provide vehicle information even when license plates are not visible.
