Instalation help please

Hi. I have an awning on the facade and need to install the camera above this. The camera therefore needs to protrude from the wall or the sensor and the camera will be sitting on top of the awning and won't be of much use. I need to attach something to the wall and then attach the camera to this. Anyone have any ideas what I could use please. I've looked to see if there's any kind of bracket I could use but can't find anything. :(
