For what it's worth; When I lived in Arizona, come sundown I would go out on my deck with a cigar and a night cap. Most evenings a skunk would come by and I would just sit there and watch it watch me. After a few of these encounters I starting saying hell-o and talking to it. the skunk would look at me and just keep going about its business. Now that I'm living in PA it's common to go through the same scenario with the deer and foxes.
The wild animals around us are far more aware of us than we are of them. As long as you don't do something to startle them you should be fine. As far as the camera tripping, the critters might take off the first time or two but, once they know it isn't a danger to them they will normally accept it as a new part of their life. As RMorrison said the spray is a skunks last resort. I once watched an animal control officer capture a skunk in an office complex by walking up to it easily with a cardboard box. He placed the box on the ground next to it with the opening facing the skunk. The skunk just went into the box, they are nocturnal and prefer the dark, the officer closed it and took box and skunk away. No fuss, no muss, no stink
