In many traffic environments successful ANPR can be challenging. Curvy, wide roads or cars covered with snow, road salt or dirt can make reliable plate capture difficult. This is particularly important for free flow parking systems where missed plates mean lost revenue. So far the solution to this problem has been to add additional ANPR lanes to cover a wide road or read front and rear plates on the same vehicle. The problem with this is that duplicate reads can be generated that would have to be filtered out manually or by third party application software. CitySync now have a solution for this using the new dual plate reading feature.
