I know, I know, not quite as lascivious as aardvark huffing.
One wonders what there could possibly be on the surveillance footage of the alleyway behind the office building, people going in and out of shop entrances, empty corridors, etc. that would be worth giving up your leisure time in order to hack the signal and steal the vision.
"We are in the back streets of Cambridge on a warm April afternoon, armed with a handheld video receiver, a small portable screen and a short antenna. There are eight of us: film-makers, activists and a couple of curious hangers-on, all about to engage in in film-making's latest form of subversion. We are spending the afternoon video sniffing.
Video sniffing encourages people low on resources, but high on imagination, to create their own media. Our mission is to capture the live feed from the network of CCTV cameras that stand sentry over so many shops and street corners in Britain. The handheld receiver allows us to scan, or sniff , wireless transmissions and view them on the screen without the owner's knowledge or consent."
