Abstract
A visible light (VL) and infrared (IR) combined image camera with a laser pointer. The laser pointer may be used for marking a hot spot on an object or for focusing an IR lens of a camera on an object. The laser pointer may be adjacent to the VL optics and offset from the IR optics. The VL sensor array may be much larger than the IR sensor array and the camera may also display the pixels of IR data with a much larger instantaneous field of view than the VL pixels. The camera may also provide audible alarms where the alarm is emitted with a tone of variable output to indicate the relative level of the alarm.
