Is it all down the lens? A standard IR camera would blur the plate back so how does a ANPR do this? Obs the software reads the plate but the camera i'm interested in.

its a filter as well to cause high contrast of the plate.

what the lens?

no a filter

Filter where? All the ANPR cams I seen have a reflective lens for some reason

no a lens filter. You need an image that wont be affected by ambient, headlights etc. PWI isnt enough on the smaller formats anymore

Yeah lens

And lots of night focussing haha

Hello, basis is you fire IR at the plate within a fixed IR range, I won't go into finer detail as not best in open environment, the retro reflective nature of the plate reflects this IR back. The camera is a normally CCD but has a special cut pass filter on it (again not for open forum) the ANPR engine also requires the video feed to be of a specified shutter speed, frame rate and quality for accurate reads. This is open environment specific.

However you can use ANPR just on standard CCTV however for reliability and accuracy obviously a tailored product is better.

If you want more in depth detail and workings by all means shout me up anytime

you say that a lot ill shout then
