mountianrider Posted November 21, 2015 Posted November 21, 2015 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. Quote
james.wilson Posted November 21, 2015 Posted November 21, 2015 its a filter as well to cause high contrast of the plate. Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

mountianrider Posted November 21, 2015 Author Posted November 21, 2015 Filter where? All the ANPR cams I seen have a reflective lens for some reason Quote
james.wilson Posted November 21, 2015 Posted November 21, 2015 no a lens filter. You need an image that wont be affected by ambient, headlights etc. PWI isnt enough on the smaller formats anymore Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
al-yeti Posted November 21, 2015 Posted November 21, 2015 Yeah lens And lots of night focussing haha Quote
Shepwell Posted February 21, 2016 Posted February 21, 2016 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 Quote
