How hard would it be to set different motion duration thresholds (not sensitivity) for night time?
Flying bugs trigger a lot of motion indexing. But they move fast so something like a rule that says motion must have a duration > X milliseconds and > X percent? This rule could be enabled by detecting when the stream has gone to monochrome (typically meaning the IR lights are on). Rain and dust are another matter altogether but getting rid of the bug motion would be a big improvement.
Might be too much overhead to try and pull color data from the stream constantly, but shouldn’t take much to pull a low res jpeg every 60 seconds or so and process that to determine rgb values for color vs monochrome? I don’t know… you figure it out ;-) Maybe you already have and a solution is forthcoming in 4.0, but the above seems like a doable low-tech idea (says the armchair engineer).
