Call Speeds and Resolutions

The following illustrations show the resolution and frame rate sent in a call, depending on the speed of the
call and the Optimized for setting of your Camera input. The values for sharpness and motion are the same
from 4 MB to 6 MB for systems that support higher call speeds.
The difference between NTSC and PAL cameras is how frame rates are calculated:
● NTSC 60 fps equals PAL 50 fps
● NTSC 30 fps equals PAL 25 fps
