What are the differences between a thermal camera and an infrared camera, and how do these variances impact their respective functionalities and applications?

A thermal camera detects heat emitted by objects and displays it as a thermal image, while an infrared camera captures infrared radiation and converts it into a visible image. The main difference is that thermal cameras can detect temperature differences, making them useful for detecting heat leaks and monitoring equipment. Infrared cameras are more versatile and can be used for various applications such as night vision and medical imaging.
