There's some you tube videos on it, I would think getting the correct camera arm would make life easier, seems like they usually throw in a few go pros for good measure. I've played around with GoPros, for up close they are simple and you can turn them on via the app on your phone, I had a buck come in at about 80 yards last year and recorded for about 10 minutes but it was to far out to get good content out of it, really wish I'd have had an arm and a bigger camera at that point, but it all comes down to how much junk you want to bring with you. A go pro, battery, and screw in flexible mount don't take up much space and are pretty versatile.
