I have tried the v3 software, but I have not found any place in there to adjust the light sensitivity. I do not do any recording, I only use the camera for live viewing, so adjusting the movie setting would not help me much. This camera was advertised as 1.0 lux, so I assumed it would at least pick up in lower lighting with lights. I am not sure what the 900 was, like 2.0 or 3.0 maybe, but it defiantly picked up more light than the 920. I did change the picture quality from medium to high, and that SEEMED to help with the wash-out at higher light.
