New to the home surveillance thing, I just purchased the 3 pack XT2 cameras and have them in the “Wall Mount Bracket” weather case. The front of the camera is still totally exposed to the elements. Cameras are performing as expected. I’m in the Bay Area and we get a lot of rain and fog. What’s on my car windshield I expect the same on the camera lenses.
RainX comments here came w/a warning. I use “Sea Drops” Anti-Fog and Lens Cleaner. It’s nonabrasive and made for dive masks (that’s why I have it) so I thought why not, and it’s working really, really well. I put just a dab on the lens and sensor (a little goes a long way) and wiped it clean with a soft cloth. TIP: Irregardless if you use a “defogger” on your cameras, clean the lenses before you put them up! I don’t know if it’s the Sea Drops or just a matter of dirty lenses, but after wiping them down the picture is much sharper and colors pop.
