RF emissions
CISPR 11
Group 1
The USBCam system uses RF energy only for its internal
function. Therefore, its RF emissions are very low and are
not likely to cause any interference in nearby electronic
equipment.

USBCam system requires continued
operation during mains interruptions,
it is recommended that the USBCam
system be powered from an
uninterruptible power supply or
battery.
