The irony of all this is that the bar probably has a security camera system that's recording everyone all the time anyway.
The intent of the camera system is to have evidence if an incident occurs. I doubt the bar owner is going through it at the end of the night looking for which parts of it are interesting enough to post on Facebook.
BTW, there are already a ton of cell-phone videos taken at that bar and posted to YouTube, so I doubt having a new type of recording device is actually going to make a difference:
