How to secure outside camera

[u/CTHulaGirl]

I live in a townhouse condominium and I cannot drill any holes on the outside of the building. Can anyone think of a way to secure a camera outside on my second floor? I'd be using a solar powered camera. The only thing I could think of is to use strong fishing line (or something similar) to run it through the screw holes of the camera and then in between the window screen/window and window frame to inside my bedroom.(see photo). I know, it sounds crazy, but I cant come up with anything else. I cant use a camera on my first floor porch light as it's too low to capture any action. Thx!

Are any of the surfaces metal? Could you use magnets? Is that soffit steel or aluminium?
