When Apple added AirPlay video mirroring to the Apple TV with the launch of the iPad 2, it opened up a world of new possibilities for developers and users alike—including one possibility that, while somewhat silly, might someday come in handy someday. If you own both an Apple TV and an iPad 2 or iPhone 4S, you can use one of the latter devices as a remote camera, which you can view from the Apple TV. Simply double-tap the Home button, swipe over to the media controls hidden in the multitasking tray, tap the AirPlay button, select the Apple TV you wish to use, and turn on Mirroring. Once that’s done, all you need to do is open a camera app on the portable device, and whatever it’s looking at should appear on the screen. This is great for static surveillance jobs, but what if your subject—say, a child—is on the move? Simply strap one of the devices to a remote-controlled vehicle and you’ll be able to keep an eye on the entire house—or at least that floor. [via TUAW]
