Do you really think it is the camera or the scent from you being near it? I can't imagine that the deer really care about the camera. I have never had an issue with the flash,and I have had more deer sniff the no-flash Cudde that I have than the flash. It blinks red lights and they notice that too. I just have never seen a deer that gave a crap about flashes or lights in general. They don't know what that light is. Could be lightning for all they know.

I am no expert. I am only speaking from my experiences.
