This 6 year old network camera is hard working but has collected some dust on its lens. The video output is a little blurry.
Step 1: Cleaning Materials.
Using Rubbing alcohol and paper towel I went about cleaning the lens.
Step 2: Cleaning.
I wet the paper towel and gently wiped the surface of the lens. I pulled off some dust from it.
Step 3: Done!
Now the lens is clean and the video output nice and clear!
