The most frequently asked question to thermal imager manufacturers is certainly: “How far can the IR camera detect a target?”; It is indeed a good criterion to qualify one sensor from another considering the final application. And the answer given to this question will probably include the “DRI ranges” expression.

DRI stands for Detection, Recognition and Identification. DRI ranges, expressed in km (or miles), can be found in the specification tables of SPYNEL Solutions brochures. In order to select the right sensor meeting the application requirements, these DRI ranges have to be perfectly defined, but also assessed with regards to globally adopted industrial standards.
