Re: [Motion-user] Flashing Video

[alexandre g. <ag...@tk...>]

Tried with lowering the framerate and also raising the threshold to get 
around my 12 year old webcam outputting flashing (darkly/lightly exposed 
video output) and falsely triggering motion recording.

I relented and purchased some $8 Dorhea OV5647 RPi camera module.  Much 
better quality and no false positives since!
