Visited my DNR-202L/3 2330L/1 960L/DIR 890L install site.
2 cams underneath in an enclosed screened patio/over hang.. maybe 6-7ft extension from home... even though tonight was very low humidty, the moisture collected there and pretty much made the IR worthless... too much reflection...
Other issue was installing under roof overhang for front door... it was like the IR was worthless perched above trying to illuminate the path the front door.
Also, the 960L looked under some strain at night in a big room....
So more IR lighting is definitely needed...
