As small, portable, and affordable as the technology is getting these days I got to think it is pretty easy to set up, even in a hotel.
I always quickly walk the suite to make sure we are alone but really never gave much thought to cameras used to record BCD time. I wonder if somebody has a video of me in action?

As far as security cameras in public areas (lobbys, parking lot/garage) I know I'm on tape and don't worry too much about it & just view it as a small but inherent risk on takes.
