Seek Thermal. They make cameras that attach to your smart phone (Android or iPhone). As a Certified Level 1 Thermographer, I (Dave) bought one of these to test out. The results so far have been impressive, and this Saturday it goes on its first investigation with us. Check out www.dtig.net on Sunday night after 6pm to read about how it works for us, battery life on the phone, any evidence it might capture and much more. At left is a coffee maker doing its thing, taken with the Seek on a Samsung S4. Did I mention it only costs $199, and that includes shipping?
