Question:

What are the detection ranges for the various Photon/lens versions?

Answer:

This question has many variables that must be considered, and some of those variables are inter-related. We make some assumptions to simplify the problem, but it is important to note that this type of question (what can be seen at what distance with an particular IR camera system) is typically approached in terms of target detection, recognition & identification ranges, along with an associated probability of success. Typically the result will be communicated in terms of a percentage probability of a particular target being detected, recognized and identified and certain ranges. There is a standard set of conditions regarding targets and defined meaning for the results that allows some simple test measurements to be fed into models that provide range outputs. Where applicable, our assumptions are consistent with standard range modeling.

We have compiled two charts that provide the nominal detection, recognition, and identification ranges for the different Photon versions. One chart is based on a person-sized object the other on a 2.3 meter vehicle-sized object.

1) Detection, Recognition, & ID of Human Target
2) Detection, Recognition, ID of 2.3m Vehicle
