14AXIS 216FD - Video Streams
Video Streams
The AXIS 216FD provides several different image and video stream formats. The type to use depends on your requirements and on the properties of your network.
The Live View page in the AXIS 216FD provides access to

Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on the properties of your network. The available options in AMC are:

AMC will negotiate with the camera to determine exactly which transport protocol to use in the order listed above. This order can be changed and the options disabled, to suit any specific requirements.
