The black Kensington Proximo Starter Kit for iPhone 5/4S With One Additional Tag is a kit available exclusively from B&H. Included are a total of two circular dongles and a key fob that allow you to track your iPhone 5/4S, keys and two additional items like a camera, briefcase, bag or anything else you want to keep tabs on. A built-in loop on each makes it easy to attach them to your tracked items.
To get started, download a free app to your device and pair your phone with the dongles and key fob using Bluetooth 4.0. If your phone and items are over a customizable distance (30 - 50') away from each other, you'll hear an alarm. The dongles and key fob each use a replaceable lithium coin battery that lasts for up to six months. A maximum of five Tags (sold separately) can be used together to track additional items.
