Billboards With Spy Cams

from The New York Times

Advertising is often measured successful by being able to deterime how many people see a particular advertisement, when they see it, who they are. All of that is easy on the Internet, and getting easier in television and print.

Billboards are a different story. For the most part, they are still a relic of old-world media, and the best guesses about viewership numbers come from foot traffic counts or highway reports, neither of which guarantees that the people passing by were really looking at the billboard, or that they were the ones sought out.

Now, some entrepreneurs have introduced technology to solve that problem. They are equipping billboards with tiny cameras that gather details about passers-by — their gender, approximate age and how long they looked at the billboard. These details are transmitted to a central database. The cameras, they say, use software to determine that a person is standing in front of a billboard, then analyze facial features judge the person’s gender and age. So far the companies are not using race as a parameter, but they say that they can and will soon.

The goal, these companies say, is to tailor a digital display to the person standing in front of it — to show one advertisement to a middle-aged white woman, for example, and a different one to a teenage Asian boy.

Over Memorial Day weekend, one of these cameras was installed on a billboard on Eighth Avenue near Columbus Circle in Manhattan that was playing a trailer for “The Andromeda Strain,” a mini-series on the cable channel A&E.

Organized privacy groups agree, though so far the practice of monitoring billboards is too new and minimal to have drawn much opposition. But the placement of surreptitious cameras in public places has been a flashpoint in London, where cameras are used to look for terrorists, as well as in Lower Manhattan, where there is a similar initiative. Although surveillance cameras have become commonplace in banks, stores and office buildings, their presence takes on a different meaning when they are meant to sell products rather than fight crime. So while the billboard technology may solve a problem for advertisers, it may also stumble over issues of public acceptance.
