Have attached to the aluminum front door with the tape a camera. The fact should be mounted with 2 screws. But I did not want to damage the door because their life well exceeds the usage time of the camera many times ... The camera keeps anyway bombproof. On the problem of peeling of the red protective film: as I have each lifted a corner with a small screwdriver and then can be pulled effortlessly this also. When the power is removed, I still give some feedback to the shedding of powder-coated aluminum ... but may take as 1-2 years ;-)
