Operating the smart camera above the specified ambient temperature or
above the specified case temperature will degrade image quality and can
cause permanent damage to the device.

The smart camera also has a internal temperature sensor that provides an
internal temperature measurement. You can monitor the temperature sensor
from LabVIEW using the Status Information»Temperature property

Mounting the NI Smart Camera
Caution
If you choose not to mount the NI Smart Camera to a thermally conductive
structure, do not position the smart camera with the heat sinks resting on any surface.
Doing so may violate the thermal requirements of the smart camera and cause the smart
camera to overheat. Refer to Appendix A,
