GPS
The system(s) listed below may be equipped with a GPS unit that provides the coordinates of the location of the equipment – thus enabling you to track where the actual measurement is performed.
The time in the system may also be synchronized via the GPS unit.
Infra-red
The system(s) listed below may be equipped with an infra-red camera that uses an invisible flash so that it will not be seen when a photo is taken. This may be convenient for example in residential areas where one does not wish to disturb residents with a white visible flash. The images will be black and white with the infra-red option.
