Aesthetics of CCTV's

I found an interesting article about the look of CCTV's. I have previously written a lot about the function and ethics of the surveillance cameras but haven't thought much about the design and aesthetics of them. It is a sort of of object you assume to always look the same even though I as a product designer should not think so. With making the design nicer the feeling about the whole system could be different. I collected few example of different designs of the cameras below.
