Why do Dahua plate recordings exist but blacklist alarms never fire?
Answered by ANPR AI·Sourced
Short answer
Recognition and list-alarm linkage are separate settings.
Explanation
The cited legacy NVR manual distinguishes regular plate events from blacklist and whitelist events.
Things to check
- Imported lists
- Selected event type
- Alarm linkage
- Schedule
What to do
Configure the relevant list and its alarm action, then test a matching plate. Confirm menus against the installed recorder version.
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
