I have painted 8 V2’s and would like to share my method:
Read and look at pictures below.
Un-box the camera and save the inner cardboard camera wrap.
Cut and fold the wrap to fit inside the recess on the back of the camera.
Place some tape over the bottom camera label to keep from painting it.
Place a fifty-cent coin evenly over the lens, light sensor and mike opening.
Keep spray nozzle about 10” from surface. Make multiple light passes from different angles and directions; not too close or the coin will be dislodged. I have good results with enamel paint.
I don’t normally paint the back as it is not seen in my camera installations but overspray does provide a little wrap-around effect. I also don’t paint the adjustable undercarriage because I like a compact install.
When dry remove the coin and the protective tape over the camera label on the bottom.
Note there is a narrow paint transition effect where the edge of the coin was.
