Nope, and in case of crime, most local police forces can simply walk into local stores and request recordings from the last X days, so quite why they'd need illicit backdoors, I don't know. I'm also entirely fine with this. Backdoors in cheap CCTV being accessed illicitly at a mass-level is an entirely different problem, and one which I'd agree would need questioning. I doubt there's much value in that concern for another decade, until the majority of CCTV cameras are ultra high resolution/30+fps, which they're not.
