Remember the FLIR ONE Thermal Camera? It was an awesome iPhone 5s accessory for catching thermal leaks and seeing things in the dark. The first generation FLIR ONE was a decent device, but it was not compatible with all iOS or Android devices. The 2nd generation FLIR ONE is a lightweight accessory with two cameras to bring live infrared imagery to your phone. It relies on FLIR’s patented MSX technology to provide you with thermal images.
You can use your FLIR ONE to detect energy leakage, monitor folks in the dark, and even see animals at night. The new version is portable and easy to take around. You will have to wait a bit to get your hands on one.[Source]
