An infrared thermal camera can be installed in a vehicle, such as a car, to provide different capabilities including night vision, passenger temperature monitoring, liveness detection, and avoidance of collisions with animals. The camera may be located inside the vehicle facing outwards through the front windshield. The camera may be used in multiple modes. In a first mode, the camera may be used to provide night vision or other thermal imaging of a scene outside the vehicle using a first field of view. In a second mode, the camera may be used to provide thermal imaging of a scene at least partially inside the vehicle using a second field of view, which may be useful, for example, for scanning the skin temperatures of occupants.

A thermometer includes one or more temperature sensors mounted on a housing. The one or more temperature sensors determine a temperature of at least one measurement site without contact. The non-contact thermometer displays an indicator to assist alignment of the one or more temperature sensors with the at least one measurement site, receives at least one measurement reading from the at least one measurement site, determines a temperature based on the at least one measurement reading, and displays the temperature on a display unit.
