Mobile LPR

Hello, has anyone used old camera systems from DRN or likewise with OpenAlpr? I am wanting to use a good LPR camera system for repoessesion work. Any help with this would be apprerciated. Has anyone developed their own mobile LPR camera system with consumer hardware? Thank You.

i have been looking for a reliable source as well using ip cameras, non drn. most of the lpr programs do not gps tag and are designed for parking lot/stationary mounting
