Under specific conditions, some Axis thermal cameras are capable of precise temperature measurements, but they are not designed by Axis for the specific intention of human fever detection nor the diagnosis, mitigation or prevention of disease or health conditions. Thus, Axis thermal cameras are, for example, not approved by FDA in the US for this use.

Temperature detection

AXIS Q2901-E offers two kinds of alarms triggered by a deviation of the temperature: if the temperature goes above or below a set limit, or if the temperature increases too rapidly. The camera can detect the temperature of an object between -40 °C to 550 °C (-40 °F to 1022 °F). The accuracy is +- 5 ° in temperatures below 150 °C (302 °F).

Isothermal palettes

Isothermal imaging makes it possible to configure highlighted temperature-spans in the image. They help to define which temperature corresponds to which color. The Lower limit denotes the temperature where the colored part of the palette will start and all temperatures above this limit will stand out.

Spot temperature reading

This capability is used to view the temperature of a particular area of the image. The emissivity can also be adjusted (depending on the material characteristics) to get a more precise reading. Used as a visual aid for an operator.

For demanding outdoor video surveillance

AXIS Q2901-E is a bullet-style outdoor-ready model that is designed to withstand harsh weather conditions. It comes with a built-in heater for the window. The camera is further protected with shock detection, a capability that sends an alarm to personnel during attempted vandalism.
