Rekor Scout reads live video from most IP, traffic, and security cameras and provides real-time vehicle recognition results in any browser.
Rekor CarCheck accepts still images of vehicles and returns plate and vehicle information as structured JSON for easy integration into your own apps.
The platform returns plate number, make, model, colour, and direction of travel rather than the plate alone.
