Thermal cameras are expensive, which is why they're mostly used by firefighters, contractors and psychotic aliens. Fortunately, that's all about to change thanks to the FLIR One, which is an iPhone case with a tiny thermal camera stuck on the back. All you have to do is strap your iPhone 5 or 5s into the dock and, once you've downloaded the app, you're ready to go. Using multi-spectral dynamic imaging, it can create hybrid images, adding extra detail to the thermal pictures, or plain-ol' thermal pictures in the dark. When you point it at a subject, the FLIR will also give you a temperature reading of what you're pointing the device at.
Flir One hands-on
It took FLIR more than two years of research and development to create Lepton, the camera necessary to make this happen, which is smaller than a nickel. Despite its tiny size, it's much cheaper than normal thermal lenses, which would normally set you back around $1,000. The company hopes that this will help DIYers to find the leaks in their home, outdoors types to avoid wild creatures and families to navigate dangerous areas like smoke-filled houses. It'll be available in the spring for $350, with an Android version planned for later in the year.
