I don't have the ability to mount anything on the exterior of my house but still want to have a camera, so my current idea is to have one looking out of a window. Obviously this isn't ideal - but its what I'm working with. I am after suggestions of what I can do with either a bullet or pinhole camera to make it less obvious there is one looking out of the window. I'm thinking of simply putting it inside an ornamental type box with an appropriate hole drilled in it. Does anyone have any suggestions of what wouldn't look out of place on a windowsill that could house a camera ? To get the angle I'd need to see over a roofline to where I park my car the camera would need to be right at the top of the window.
