So I messed up big time and hopefully someone can help
.
I upgraded a camera and moved the camera that was at it's place (the Dahua dual cam AKA booby cam dome LOL) to another location that isn't critical and was going to be used as overview cams for an area already covered.
While I was repositioning the two cams for the new location (which with a dome means the dome cover is off), a burst of wind with dirt dust decided to blow by and stuck to the lens. Given it was the lens itself, I didn't want to touch it and blowing on it didn't get it off.
So I decided to use a can of compressed air and had it perfectly level and started the air off of the camera and cleaned the one lens off and then the next lens as I turned to it the frozen white gas spray came out and within a few seconds it appeared the coating was damaged. Looking at the camera on the GUI was a big mess right in the center of the frame.
So I decided to wipe it and clearly the coating is now gone when looking at the two lens you can see a difference between the two.
Now the entire image is blurry. Does the coating actually result in messing up the focus or is there now a smear residue that I need to remove? If so, what should I use?
Again, it isn't a critical location and is an overview camera, but I would like it to not be blurry LOL. Lesson learned...and another reason to avoid domes LOL.
