Compliance, safety, and intended use
Housed cameras: handling hot cameras
If the mainboard temperature exceeds the specified maximum for more than two
seconds, the camera is powered off automatically. The current value for mainboard
temperature is output by
DeviceTemperature. You can use this value to control
cooling by software, for example, to control a fan.
However, if you hold the camera in your hands during operation, your skin may get
hurt. If you touch the camera when it is heated up, we recommend wearing
protective gloves.
Providing optimum heat dissipation
Design bare board and open housing cameras into a heat dissipative housing with
a high thermal conductivity. For more information, see Mounting bare board
cameras on page 260. Keep the operating temperature in the specified range to
enable best image quality and to protect the camera from damage. Temperature
values apply to a relative humidity of 0 to 80 percent that is non-condensing.
For your safety and to improve camera performance, operate the camera:
• Mounted to a base with a high thermal conductivity
• With lens or other optical components mounted
• With a heat sink mounted that has large surface areas (closed housing cameras
include a heat sink)
• Using conductive media for camera and heat sink mounting
• With active cooling of camera, mounting base, and heat sink, such as by
ventilation.
• Reduce high ambient temperature. For example, in outdoor applications with
direct sunlight, provide shading by an enclosure.
See Figure 7: Setup to provide optimum heat dissipation on page 55.
