Techniques are disclosed for systems and methods using small form factor infrared imaging modules to monitor aspects of a power system. A system may include one or more infrared imaging modules, a processor, a memory, a display, a communication module, and modules to control components of a power system. Infrared imaging modules may be mounted on, installed in, or otherwise integrated with a power system having one or more power system components. The infrared imaging modules may be configured to capture thermal images of portions of the power system. Various thermal image analytics and profiling may be performed on the captured thermal images to determine the operating conditions and temperatures of portions of the power system. Monitoring information may be generated based on the determined conditions and temperatures and then presented to a user of the power system.
