Why can an old Stream plate event arrive after the network recovers and reopen a barrier?
Answered by ANPR AI·Sourced
Short answer
Queued webhooks may be delivered later.
Explanation
Stream documents cached delivery. The stale-event gate risk is an integration-design inference.
Things to check
- Event timestamp
- Receive time
- Queued backlog
- Gate rule
What to do
Make the receiver validate freshness and handle repeated messages before using an event to authorize an immediate gate action.
ANPR Edge
Skip the dedicated ANPR camera. Read plates from the cameras you already have.
ANPR Edge is plate-recognition software that runs on a PC at your site and works with ordinary IP cameras, so plate reads no longer depend on one vendor's camera, NVR or firmware.
- Works with standard IP cameras over RTSP
- One license per location covers every camera
- Runs on a Windows PC or Mac you own
