Hi All Just have a little problem I can't seem to make go away so I'll put it out there and someone might be able to tell me what I've done and how I might undo it. I had a play last night in the browser interface for the camera which looks down my driveway. I disabled Smart IR and enabled it again wanting to see what the difference would be like and now I've got a grainy view. Previous to this the view was crystal clear and sharp. Adjusting other options can make this graininess better or worse such as WDR (was set to 20 before this and wasn't an issue) and DNR ( was left at the default 50). I'm running v5.1.0 firmware. Can anyone help me? Edit: Forgot to mention that daytime vision is perfect. I've got another 2CD2732F-I which looks across my front yard which doesn't have this issue. Edit: Added before and after pics to show what I'm going on about. It's raining when but shots were taken. Thanks in advance.
