Infrared scans for moisture intrusion are typically performed with a high-resolution IR camera, such as a FLIR camera, model T420, Minimum resolution of 320 x 240 pixels is required for moisture work. Other acceptable cameras are manufactured by Testo, Fluke and Palmer-Wahl...just be sure and check the resolution; ask your infrared imaging tech just to be sure! And make sure the tech is (at least) a Level I Certified Thermographer.
