3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
passive infrared detection system
device that converts the infrared thermal radiation from the surface of an object into a discernible image signal(s) by means of an infrared optical system, an infrared focal plane detector and an electronic processing unit

reciprocal of the time interval between two adjacent frames
Note: Expressed in Hz.
3.4
white hot mode
mode in which higher thermal IR energy is mapped as high brightness and lower thermal IR energy as low brightness for display
