The C3 Series Automated License Plate Recognition (ALPR) camera can be supplied with a range of different internal camera and infrared (IR) illumination options offering unmatched flexibility - suitable for any ALPR application including mobile, fixed site and long range ALPR.
A principal feature is the use of high-resolution optical zoom cameras - both for ALPR and high-definition overview/contextual imaging. Zoom functionality means the C3 Series can be rapidly optimized to suit differing plate and environmental conditions at ALPR capture points. The C3 Series can be easily moved from one location to another and the settings simply adjusted - avoiding the need for time-consuming, risky and costly re-lensing.
Globally, license plates have widely differing characteristics and contrasts. The C3 Series overcomes this problem by having a choice of IR wavelengths available - 810,870 and 940nm. Zoom functionality enables the camera's field of view to be optimized to local plate sizes. Additionally, both IR pulse duration and illumination power can be adjusted by the user. In its long range, dual illuminator configuration the camera has a range of up to 150 feet (subject to wavelength).
Obtaining high confidence recognition results in bright sunlight, when plate characters are partly shaded, is a significant challenge. At night, the effect of bright headlights needs to be suppressed to improve the accuracy of recognition. The C3 Series has a number of features designed to combat these problems, including improved processing gain and narrow band IR filtering.
