i have the exact same issue, installed a Hikvision 2.8mm dome camera in the center of the front house wall, thinking it will be enough to capture my 2 cars, side-by-side driveway, but nope, it does not capture enough area. have been thinking if a turrent camera will improve coverage

How are you building a database to search through...my idea is just for flair. I want to have announcements in my house when our friends arrive based on plate recognition.

There are cameras with internal ANPR that can automatically trigger a built in relay if a plate matches it's internal database.
Nest Hello + Google Home can do this using facial recognition at your door.

fyi: user networkcameracritic passed away several years ago, this is a pretty old thread.
