At the recent ASIS show in Las Vegas, among booths where vendors hocked everything from locks to tasers to bomb-sniffing dogs was a booth for a vendor selling Graffiti Cam. The portable, covert surveillance camera detects "graffiti-related motion," snaps pictures and e-mails them to the police as it sends text messages to their cell phones that say, essentially, "Hey, get down here." All the while, it collects TV-quality video on a tamper-resistant, encrypted memory card.
At only US$5,000 per camera, Graffiti Cam seems like a home run. It arrives at a time when public surveillance has gained tacit, creeping acceptance and when graffiti has become a $12 billion migraine for cities and towns--a kind of aerosol spam that they desperately want to scotch because it's bad for business. Social scientists call this the broken windows theory: Vandalism leads people to sense a place is unsafe and broken down, so they leave, which in turn makes the place actually become unsafe and broken down. Reality follows perception.
