ANPR
Number plate webhooks from cameras you already own
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
- 1
Point a camera at us
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.
- 2
Turn on plate recognition
One toggle per camera. Recognition runs after the event is stored, so it never delays delivery of the motion alert itself.
- 3
Filter to what matters
Fire on any plate, or only on plates you list. Useful for opening a gate for known vehicles while ignoring everything else.
- 4
Get the read
The webhook carries the plate text, a confidence score, and the exact frame it was read in with the bounding box.
What you get
- Works with cameras you already have — no ANPR-specific hardware
- Every read comes with a confidence score and the frame it came from
- Vehicles are grouped over time, so you can see every visit by one plate
- Filter webhooks to a specific plate, or to any plate at all
- Burned-in timestamps in the corners are ignored rather than misread
- Low-confidence reads are hidden by default and never start a new vehicle record
Questions
How accurate is it?
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.
Do I need a special ANPR camera?
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.
Can I open a gate with this?
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.
Is plate data regulated?
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.
Try it with your own camera
Add a camera, point its email at the address we give you, and watch the first event land. It takes about five minutes.
