Seek Thermal Phone Camera. It’s a small device that you can plug right into your phone’s Lightning port (if you have an iPhone) or micro USB port (which works for most other smartphones.) The Seek camera sensor is packed with over 32,000 thermal pixels to create a visible image of whatever it is your phone is currently pointed at–even when you’re in the dark. This makes checking out leaks or finding Fido way easier and faster.
