ANPR
Dedicated ANPR cameras are expensive and usually lock their reads inside their own software. NVR Bridge reads plates from the snapshots any camera emails us, then fires a webhook — optionally only when a specific plate shows up.

}How it works
Any camera that can email or upload by FTP. It doesn't need to be an ANPR camera; it needs a reasonable view of the plate.
One toggle per camera. Recognition runs after the event is stored, so it never delays delivery of the motion alert itself.
Fire on any plate, or only on plates you list. Useful for opening a gate for known vehicles while ignoring everything else.
The webhook carries the plate text, a confidence score, and the exact frame it was read in with the bounding box.
What you get
Questions
Good enough to be useful, not good enough to be evidence. Every read carries a confidence score, and you should verify before acting on anything that matters — we say the same in our terms.
No. Angle and resolution matter more than the badge on the camera. A normal camera with a clear view of where plates sit will read most of them.
You can fire a webhook on a specific plate, which is what a gate controller needs. Given recognition is probabilistic, pair it with a fallback that doesn't strand someone at the gate.
In some places, yes — plate data can identify a person indirectly. You're responsible for having a lawful basis to collect it. Our acceptable use policy covers what's not allowed.
Add a camera, point its email at the address we give you, and watch the first event land. About five minutes, all of it in a browser.
