Nightime Halos?

[PeteCress 0]

Cam's image looks a-ok during daylight: http://tinyurl.com/m6re5zk

 

But after dark: http://tinyurl.com/k5nweb7

 

Also occasionally it goes hazy during the day: http://tinyurl.com/l3cwmbb

 

On this cam, I had replaced the stock lens with something more wide-angle (3mm IIRC); but my recollection is that those halos were not present immediately after the replacement.

 

Moisture in the camera was my guess and, indeed, found water in the cam when I disassembled it.

 

Gave the parts a couple days to dry out, reassembled with some silicone in the joint, but no change.

 

Now I'm thinking either I needed to dry the case/parts more thoroughly or the body is still leaking.

 

Before I start tearing this thing apart again, can anybody suggest some other cause?

That's definitely a cool effect. There's gaps between the lens and the lens or the hood that separates the lens from the IR LEDs. How to fill it is a science experiment, maybe tape some foam around the lens to act as a hood.

Definately looks like the IR is hitting the hood/cover, and causing this reflection. I just had similar problems with my old HLC-1NAG, for now i solved it by taking the hood/cover off, but that wont work for you since it seems that cam is outside.
