Mounting the camera upside down
The camera may also be mounted upside
down. This may bring camera and monitor
closer together and thus contribute to a
better feeling of eye-contact between the
video meeting participants.
The orientation of the camera is automatically
detected when the camera is powered—no
manual setup is required in order to display
the image correctly on screen.
