So you've found the perfect spying device, a pinhole camera built into a tie that's "virtually impossible to detect with the naked eye." Its high-resolution video can also be seen on a 2.4-inch LCD screen that fits neatly on its cigarette-pack-sized recorder that holds up to 4GB of data, complete with remote control. All this doesn't come cheap--nearly $1,300, actually--but it's worth it because no one will ever suspect a thing, right? There's just one problem: You never wear a tie.
