A thermal imager is a high-resolution infrared camera that allows users to “see” objects without visible light. It uses a special type of sensor that detects infrared radiation and converts it into an electronic signal that can be displayed on a screen. This technology is widely used in firefighting, night-time law enforcement and disaster response search and rescue.More info :thermal-imaging.uk

Thermal imaging cameras work by detecting infrared (heat) energy that is naturally emitted by objects. This energy is detected by the sensor and converted into an electronic signal that the software can interpret into a visual representation on the display screen. Because these devices use a passive technology they can be used in complete darkness, or in conditions where other types of imaging equipment would be impractical or impossible.

Choosing the Right Thermal Imager: Factors to Consider Before Making a Purchase

Depending on how the thermal imager is configured and operated, it can be used to detect and locate a wide range of problems. For example, an energy auditor may prefer a lower-cost point-and-shoot model that can be easily carried in a jacket pocket to quickly spot missing insulation, poor weather stripping, and drafty windows. Or, an electrician may need a more advanced model that can capture and upload professional-quality images to secure cloud storage for future reference.

The quality of the thermal image depends on several factors, including the size and resolution of the sensor array. Fire service models are typically configured with detectors that have 80×60, 120×120, 160×120 or 320×240 pixels. The higher the resolution, the better the thermal image quality will be. However, other factors, such as the quality of the processing hardware and software, play a greater role in overall picture quality.
