Vivotek LPR Blocklist Allowlist event rule issues
Completed
Hi.
I am trying to get NX witness to perform various actions when cars on the allowlist pass the camera. I have managed to get cars not on list to trigger both mobile notifications and book marks but i cannot seem to get plates on the allow list to do the same. If a plate is on the allow list it doesn't trigger anything. I realise that there is something very simple i am not doing when setting up the rules. I have tried putting ALLOWLIST in details when setting up the rule but to no avail. any advice or directions to resources that could help me would be most appreciated

Hi Chris,
Could you please provide a screenshot of the existing rule for better understanding?
Also it worths checking Wireshark capture to see what information is send by the camera when the license plate from the allow list is recognized. Most probably it will show you what information is missed in the rule.

Hi Chris,
"ALLOWLIST" is not an attribute, it is not usually sent by the camera. What happens if you leave "attributes" field empty? How is this behaviour configured on the camera side?
Also, probably it works with Generic Event, not with Analytics Object Detected, so you can try to use Generic Event with an appropriate <event.caption>. It also can be checked in a network capture.
Regarding Wireshark, you can follow this article: https://support.networkoptix.com/hc/en-us/articles/360053308054-How-to-create-a-Wireshark-capture. It is necessary to check what request is send when the camera discover any allowed license plate and what information is included into that request.
