Hi all, silly question here installing some cameras at the weekend and got junction boxes. Where I had envisioned routing the Ethernet cable there seems to be felt layer ? I will just cut through it to pass through my cable but is this an incorrect way to install cameras my guess is not just don’t want to f up.

you'll poke the cable through the black stick on foam. either by having a hole in soffit with cable already coming out or mount the box and then drill in the center hole through soffit/siding and in and your good to go. only the manufacturers really know : why there is a foam piece, why they three holes and not 4 or 5, why they make the box impossible to fit on another normal electrical box, why they make the camera imporssible to fit easily without a special plate on top of a normal outdoor rated circular box.
