Our recommended upload speeds vary based on the video resolution you set for the doorbell.
1080p - 2 mb/sec/camera
720p - 1.5 mb/sec/camera
480p - 1 mb/sec/camera
Please note that the speed requirements are on a per camera basis because if multiple cameras stream at the same time, then the speed requirements would sum together. During an alarm, for example, all cameras will record footage.
