the camo is a 3D pattern done with Latex caulking right out of the tube and ''no painting''
this is the best way i have found to camo the camera units as it really works good to hide em in the woods when it looks dang near the same as the tree does....hehehe
the camo is done by using what is called ''white lightning'' caulk found at most all builders supply .
you can get it in several different colors to match what you need . i use the brown , gray and cedar colors as that is what is on the pic above.
simply apply it in several beads one atop another until you get the desired texture thickness you want.
i also use a course bristle brush such as a toothbrush to brush in some bark texture.
after drying the caulk makes a very durable waterproof coating that is kinda rubbery to the touch.
if you need any info on the exact process let me know and i'll be glad to help.
