Yes, carrying around a backpack with all of the receiving kit, and then processing it remotely or in the same kit. Most studies are done under idealized conditions as proof-of-concept for now. If they are close they can grab enough data, but it is still not 'there' yet to be ubiquitous; it will be soon though.
That being said, I use tape at work, and at home on my forward-facing cameras, simply for privacy insurance. Those wires don't show a masked image. Even the best image re-construction or processing algorithms need more data, although you'd be surprised how much data can be extrapolated from semi-transparent Scotch tape over your camera! Maybe you think it's ok if somebody wants to RAT you, but don't forget, some of the photos released or used for extortion are of your SO, or other loved one in the background walking around naked, or doing something embarrassing. I don't care if somebody wants to RAT me this way; they'll go blind, and they must have nothing better to do!
