For all contrast modes, a convenient way to visualize temperature values is to enable
the color map overlay (see Overlays section). This overlay is also available when the
camera is configured to output color images (with YUYV pixel format).

Mounting and Thermal Considerations

Adequate heatsinking must be provided to prevent the camera from overheating,
particularly when operated in temperatures approaching the upper temperature range
of the device. The FPGA inside the camera must always be maintained at a
temperature at or below 85°C.
Teledyne DALSA recommends connecting the camera to the system by the bottom
mounting holes of the camera, preferably having some metallic part connected
thermally to the chassis of the system fully pressed against the whole surface of the
camera bottom. This will not only prevent overheating, but also allow the camera to
stabilize to varying conditions around the system.

Additional thermal connections on the other camera sides further improve internal
camera temperature stabilization.
