As is the case with all types of technology, thermal imaging cameras and methods are constantly improving. While there is a steady increase in the resolution and clarity of the pictures obtained, sometimes it will take leaps and bounds all of a sudden.
While it is possible to get a basic device that will let you use your phone as a thermal imaging camera, and you can get cheap models online as well, these cameras are not suitable for professional use. In fact, if you look at the reviews for many of these devices, they will tell you that they do not live up to the expectation.
Here at New England Thermal Imaging, we pride ourselves in using high quality, modern tools to make sure that we give you the best report possible. Of course, these tools are coupled with experience, both when it comes to thermal imaging methods, as well as, construction methods and codes.
