Not that I would buy Dahua, but an excellent test that shows the value IPVM offers us.

I like the subtitle labeling "corridor mode" to "quarter mode".  Doh! :)

Update:

Added a section explaining Dahuas Intrusion analytics performance. the Dahua PDBW5831N-B360 ignored common sources of false alarms such as blinking lights, shadows, drastic light changes, and swaying foliage in the scene. Missed detections of people walking through the scene were common, adding a bounding box but not triggering an alarm.
