Thermal Camera Basics: Specifications and Manufacturers

This page covers the basics of thermal cameras, including their general specifications and a list of vendors/manufacturers.

Thermal cameras are incredibly useful for identifying unseen hot and cold spots, especially in electrical cabinets and switch boxes. They’re commonly used for electrical inspections indoors, providing detailed images of even small connectors and wires.

Spot thermal cameras, like those from FLIR, bridge the gap between simple infrared thermometers and more complex thermal cameras. These devices often feature micro-thermal sensors.
