AXIS Q2901-E PT Mount 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). 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.
