Command Strips are fucking magical, properly applied they hold a fucktonne of weight for their size and they come off again with minimal damage to the wall/paint. Good shit. 

When I had my three camera CV1 setup, I used command strips to hold the cameras up in the corners and they stayed there solidly until I finally took them down when I replaced the CV1, which only happened recently. 

Make sure you use "Real" ones and get them oversized since the lighthouse will vibrate, do that and you won't have any worries I fucking promise you. 
My fucking curtain rail is held up with two tiny command strips and it's been that way for years since I can't be fucked to fix it after I tripped and ripped the screws out of the wall.
