what hardware cctv to aluminum soffit

D270

Hi,
I'm looking for idea how best to attach a cctv camera below my aluminum soffit. Less than a pound.

Is there a corrosion reaction I need to keep in mind?
Do I use plain old zinc coated metal screws?

And then....do I use a molly? The access from the inside is kind of sketchy...so I pretty much will be drilling a hole from the outside.

A metal screw seems like it wouldn't have enough bite...I would think I would need some type of backing to it.

Any ideas?

There is interval blocking under the soffit material. If it's not where you need it, remove the aluminum material and install blocking.
You can isolate the 2 metals with a gasketing material and use stainless steel fasteners. Zinc is for the interior.

Perhaps it would be easier to mount it on the wall, rather than the soffit. If its a brick wall you won't have any problem mounting it.
