Environmental conditions
Operate the camera in dry and dust free environment. The
working temperature range (temperature of the camera
housing) depends on the model version:
• Pearleye P-007 LWIR: 25°C ... 45°C
• Pearleye P-030 LWIR: 15 °C ... 35 °C
Outside this temperature range the image quality can be worse.
Also saturation of some regions or saturation of the whole
image is possible outside the working temperature range.
Regarding the signal quality of the camera it is an advantage to
operate the camera under constant ambient air temperature.
This can e.g. be facilitated by assembling the camera on a
bigger metal corpus or by an additional active temperature
regulation.
The red LED at the backside of the camera (L3) or the value of
the register T serves for examination. If L3 permanently
lights up or rather the lowest bit of T is set, the camera
housing has a temperature which is outside of the optimum. In
this case provide an additional heating or cooling.
Note

Warm-up period
Depending on the prevailing environmental conditions, some
time might pass after the camera start, until the image quality
reaches its optimum.
In case of simple view applications with low demands, the data
are already suitable following an operating period of some
minutes. If time stability of the temperature data is required a
longer warm up period of at least 20 minutes is recommended.
