A device comprising:

• a processor configured to:
• receive information associated with a plurality of cameras, each of the plurality of cameras having an associated camera object;
• associate a first camera object with a first viewer, the first camera object associated with a first camera and having associated first extrinsic properties and associated first intrinsic properties;
• associate a second camera object with a second viewer, the second camera object associated with a second camera and having associated second extrinsic properties and associated second intrinsic properties;
• send a registration request associated with the first camera object and the second camera object;
• and
• send an update request, the update request comprising updated information associated with the first camera object and updated information associated with the second camera object.

A method of controlling a plurality of camera objects, comprising:

• receiving information associated with a plurality of cameras, each of the plurality of cameras having an associated camera object;
• associating a first camera object with a first viewer, the first camera object associated with a first camera and having associated first extrinsic properties and associated first intrinsic properties;
• associating a second camera object with a second viewer, the second camera object associated with a second camera and having associated second extrinsic properties and associated second intrinsic properties;
• sending a registration request associated with the first camera object and the second camera object;
• and
• sending an update request, the update request comprising updated information associated with the first camera object and updated information associated with the second camera object.
