Environmental Requirements

1.2.1 Temperature and Humidity

Housing temperature during operation:

0° C ... + 50° C (+ 32° F ... + 122° F)

Humidity during operation:

20% ... 80%, relative, non-condensing

Storage Temperature:

-20° C ... +80° C (-4° F ... +176° F)

Storage Humidity

5% ... 95% relative, non-condensing

1.2.2 Ventilation

Allow sufficient air circulation around the camera to prevent internal heat build-up in your system
and to keep the camera housing temperature during operation below 50°C. Provide additional
cooling such as fans or heat sinks if necessary.

Warning!

Without sufficient cooling, the camera can get hot enough during opera-
tion to cause burning when touched.
