01
A second look by AI
Each NVR event is re-examined from the best shot and the full frame of the same moment, then judged confirmed, false alarm or uncertain. Clothing, belongings and behaviour are described in a sentence, with tags.

AI event screening
AI looks first, flags what's real
A vision-language AI takes a second look at every NVR AI event, separates real incidents from false alarms and suggests a description, risk score and response.

02
It reads the context
Scenes that trip an intrusion rule but pose no threat, such as a worker carrying cleaning tools, are marked uncertain with a lower risk. In the pilot a rule risk of 70 came down to 46.

Product description
NQVLM runs on an on-premises GPU server. For each NQNVR AI event it looks at the best shot together with the full frame from the same moment and returns a verdict of confirmed, false alarm or uncertain. Each verdict carries a sentence or two on clothing, belongings and behaviour, a 0-100 risk score and suggested responses, shown live on the screening dashboard. Scenes that trip a rule but pose no threat, such as cleaning staff, get a lower risk so operators reach real incidents first. Every event is stored before analysis, so nothing is lost during outages.
Analysis time is from a pilot with one GPU server and one NVR; it varies with server hardware and event volume.
