There isn’t a specific kb/s requirement for using a webcam with Respondus Monitor because the recording quality automatically adjusts when a slower connection is detected.
Generally speaking, if the user has a broadband connection that doesn’t result in significant delays when accessing the learning system, the bandwidth will be fine for Respondus Monitor. If using a shared Internet connection, students should ensure that others on the same connection don’t use bandwidth-hungry services during the exam (such as online movies, games, file sharing, etc.).
