Update: Camera/harness used linked below since so many people are asking I can't reply to everyone.

I put my GoPro on our German Shepherd and we left to go to dinner. I cut out her running back and forth about 3 or 4 more times from the door to the windows while we were leaving and she was whining, but she always went back to the closet and her dog bed.
