The remote control and measuring of temperature using a WEB (ThermoWEB) is based on the expansion of the measuring and operable usage possibilities of the termovision cameras NEC Thermo tracer TH7102WL. The camera's standard area for reading off temperatures is in only one central point of the obtained thermal picture of the object. By using the additional programming support it is possible to choose any point inside the obtained termografic picture of the object and get the quantitative and temporally dependent value of temperature distribution. A camera that registers the visible spectral area (CCD color camera) has been added a termovision camera, that makes it possible to accept pictures from the measuring object in a IR and visible spectral area. The camera system for measuring is controlled by a computer, which has a wireless or physical connection to the Internet. The result of these improvements is the realization of a high quality network system for remote and contactless measuring of temperature across WEB.
