Cameras


For the image capturing of the vehicle for the analysis of the number plate one needs a plate camera which must fulfill certain quality criteria.

In addition, an other camera can be integrated to show the whole scene. We call this additional camera context or overview camera, in which no special demands are made.

Nowadays the image capturing occurs preferentially with network-based cameras. However, the still common analogous CCTV technology can also be used for number plate recognition.

Number plate camera

We have carried out with different camera models of the most different manufacturers successful projects.

However, not any type of camera is equally suitable for any kind of application.

The principle is: The faster a vehicle is moving, the higher should be the frame rate (fps). With analogous cameras and framegrabber one can receive 50 half frames per second. Network cameras lie far under this value in general. However, with many applications one deals by slowly moving vehicles or even standing. Whenever a barrier is used, one can assume that the car has to stop and therefore the speed is very low while capturing the images.

We recommend the following cameras:

SONY's Industriemodul FCB-EH6300

Network camera 1.0-H3-B3 of the company AVIGILON

( see external Link www.avigilon.com )


Network camera 1.0-H3-B3 of the company AVIGILON

Mega pixel camera with vario objektive.

Advantage:

Compact construction and therefore suitable for the CAR-READER pillar.

Analogous camera CG-601PA1V of the company Fujitsu

( see e.g. external Link www.videortechnical.de )


Analogkamera CG-301PA1V von der Firma Fujitsu

The analogous camera is usable only with additional hardware. Because this camera delivers a PAL signal, a Framegrabber is necessary in the PC to digitize the analogous videosignal.

Advantage:

Sector of application: Standing or moved vehicles up to maximum 80 km/h.
