I consider offsite storage a must-have feature for surveillance equipment, because one of the prime threats is that the thieves carry off the surveillance equipment itself. With modern WiFi cameras without mounting wires and cheap plastic mounting points, that's real easy, and if you had a physical server to store the recordings it would be a target as well; the history of surveillance systems is littered with examples of "The thieves stole the tapes, too".

Finding someone trustworthy enough to store your offsite footage, though, is a real problem. If only there were some sort of union of peoples capable of causing consequences for companies that act as poor stewards of data.
