I am aware of
Blue Iris feature having more options than a standard camera motion detection.
But what caught my attention was your post that you claimed with the "right" setting in BlueIris, that we could
eliminate the false alarm. Is that 100% with pixel detection or with the aid of external motion detector like PIR sensor to eliminate or reduce the number of false alarm.
I can't see how a BlueIris would tell the different between a human being walking at a distance and a bug flying up close pass the camera Len when both look the same size in the video but the bug wouldn't trigger the alarm while a human being walking would trigger it.
I use one trick to determine which motion capture is worth checking in playback when the length of the recording event exceed the length that I predetermined which tells me there was a good amount of movement during that period.
A bug flying by would have a very short quick event while a person continuously moving around in front of a camera would have a long event.
So I am guessing that BlueIris must have some type of option to determine the length of event is worth saving and marked as alarm because I find it hard to believe that BlueIris can tell the different between two objects solely on pixels alone then again I really have not explored BlueIris option/setting deeply enough to learn it fully.
