An apparatus (10) for integrity verification of an IR detector (12) that is configured to detect a temperature of an IR emission (17) from an undercarriage component (16) is described. The apparatus comprises an IR emitter (26) which emits an IR signal (32) at a reference temperature and the IR signal is directed at the IR detector. A controller (36) is connected to the IR detector and the IR emitter, the controller is configured to compare the reference temperature of the IR signal and the detected temperature of the IR signal to determine the integrity of the IR detector.
