Thermal Overlay

Thermal overlay

Thermal Overlay simply makes sense.

A recently commissioned project has reinforced our belief that Thermal Overlay simply makes sense. Thermal Overlay mode allows equipment operators or security officers make faster and more informed decisions.

Thermal overlay uses dual wavelength cameras, a high resolution daylight camera mounted alongside a thermal camera. These cameras see two different wavelengths within the light spectrum. In broad terms daylight or visible cameras see that of a human eye, wavelengths between 390nm to 770 nm. Thermal cameras see non-visible light in the 7.5um to 13.4um range. This non visible light radiates off surfaces based on the specific temperature of that surface.

There are two basic categories of thermal cameras. Those cameras with Thermometric capability (sometimes referred to as radiometric) and those without. Both thermal camera types are compatible to the thermal overlay mode.

Thermometric Cameras

Thermometric Cameras allows any pixel within the image to accurately measure temperature. If temperature measurement is important, Thermometric is the simple choice.

Within these two basic thermal camera categories (mentioned above) performance specifications such as resolution and sensitivity are also key considerations when selecting a product.

Powerful on-board camera analytics enables the camera to be customized to the application using: pre-set thermal zones, thermal thresholds, alarms and automated responses. This offers many advantages. For example, motion detection in any light condition and over 100’s of metres, fire risk detection , equipment load assessment of discrete components and many more.

The system can also deliver hierarchical responses. As the priority rises the resulting action is elevated using on-screen indications, I/O interfaces or emailed alerts.

Thermal overlay is now a cost effective solution for mainstream applications. If you are considering a thermal camera application and are looking for product and / or advice we are willing to share our experience. Contact us at info@tracam.com.au or via Contact Us.
