We have experience with Geovision and Messoa LPR/ANPR cameras. To be clear, this is not for matching to a database or converting plate info to data, simply to provide a more highly reliable means of a human reading license plates.
We have used these specifically:
Messoa LPR606-N2-MES (discontinued)
Geovision GV-LPR110 and GV-LPR1200
The Messoa being my favorite. Its been discontinued though, so Im curious what everyone else is using with good experience (or even bad experience)
