Microbolometers are not directly analogous to cameras.
While they might look and function similarly in many ways, it's important to remember that the major difference between cameras and micrometers is that cameras are not built to make precise amplitude measurements. Microbolometers are. Cameras are primarily intended to demonstrate color and contrast. Microbolometers are intended to demonstrate contrast and absolute intensity. As a result, microbolimeters tend to be orders of magnitude lower resolution than visual spectrum cameras.
Chose your aircraft and sensor combination wisely
Because of the cost and complexity associated with conducting thermography operations, there are only a few solutions available from UAV hardware OEMs that are designed to "plug and play". If you choose to fly with 3rd party hardware, always make sure that you're within your aircraft's weight and balance limitations, and your local aviation regulations.
