I have sat in my stand and watched deer after deer stand in front of my camera with the flash going off and they don't even raise there head to see what it is. If I was a camera company and needed to try and sell the new cameras with infared sensors that don't flash i would tell people that the flash spooks deer also, don't believe everything you read when a new product comes out. If the camera flash spooks deer they will check it out and come back to it, just like when people hunt and they spook a deer, they come back around the area as soon as the all clear is given.
