Kensington's black Proximo Tag is a circular dongle that allows you to use your iPhone 5/4S to track a camera, briefcase, bag or any other item you want to keep tabs on. A built-in loop makes it easy to attach the Tag to your chosen item.
To get started, download the free Proximo app to your phone from the Apple App store. Then pair your phone with the dongle wirelessly over Bluetooth 4.0. If your iPhone and item are over a certain distance away from each other, you'll hear an alarm to help keep you from leaving it behind. Using the app, you can choose different alarm tones as well as images and create a name for your item.
Inside the Kensington Tag is a lithium coin battery that lasts for up to six months, and can be replaced later on. A maximum of five Tags (sold separately) can be used together for tracking additional items.
