And then we have Wal-Mart... > "We were contacted about two years ago by somebody who runs a security company that had been asked in a request for proposals for ways they could link video footage with customers paying for their purchases," Albrecht said. "Wal-Mart would actually be able to view photos and video of customers paying, say, for a pack of gum. At the time, it struck me as unbelievably outlandish because of the amount of data storage required." http://cryptome.org/eyeball/walmart/walmart-birds.htm http://cryptome.org/eyeball/walmart/walmart-birds.htm In general, an isolated video is not interesting. It becomes more interesting and potentially scary once you have a digital, searchable, analyzable history of video customer transactions. Reduce leakage/theft: If a cashier has been already flagged and the customer matches up in the network of cashier's friends (Facebook?), possibly in conjunction with another theft deterrent system, be able for managers to watch in real time a potential leakage event (where they don't scan certain items). Hyper-targeted marketing: (New) wedding ring detected. Commence deluge of in-kind marketing partnerships with Home Depot, maybe even Crate & Barrel. Customer over the past three months has been showing signs of possible pregnancy relative to their baseline body mass index. Somehow, non creepily, market to them via 3rd party mailing lists who had no idea how you learned she was expecting or more subtly by changing the default landing homepage of walmart.com to reflect more future mother when her cookie is detected. Kids. If the kids seem hyperactive in the overhead view, email coupons for toys that appeal to ADD-type kids. Over the last year of transactions, customer's head has been exhibiting signs of male pattern baldness. Send them targeted coupons for hats to see if they think its something they need to cover up.
