VarioCAM hr comes with an optional colour video camera, which serves the human eye to orientate in
the visible spectral range and which can be used for the simultaneous photographic documentation of the
measuring situation.
The field of view, resolution and viewing angle of the video camera will not fully coincide with the thermal
image, since different lenses are used for the two optical channels and, therefore, the optical axes are not
aligned with each other. According to the focussing of the thermal image, the resulting parallax error will
automatically be corrected.

status display "VIS"). The VIS image is focused manually with the help of the thumb wheel on the colour
video camera (camera front, see Fig. 2, page 11).
The brightness of the video image is automatically adjusted. In poor lighting conditions, this can result in a
reduced imaging rate of the VIS image. If required, the video lamp* can additionally be switched on by
