The invention relates to a device (1) for tolling or telematics systems provided with a pixel based image sensor (2). The image sensor (2) is adapted to be arranged above a surveillance zone (14) provided on a road (4), wherein the surveillance zone (14) has an extension along the direction of the road (4). The image sensor (2) is adapted to be arranged in between a first and a second end zone (6, 7) of said surveillance zone (14). The image sensor (2) is provided with a wide-angle optical system (9, 29) having a diffraction and which is arranged such, relative said image sensor (2) that an image (32, 33) captured by said image sensor (2) comprises both said first and said second end zone (6, 26, 7, 27). |
