I wanted to control the camera using the server but apparently that isn't possible, which way do I go about if I wanted to do that. Is it possible to send a message to the client to control the camera?
Try making a remote event and using :FireClient() to tell the client to run some code.
If your doing this for players.. Sadly no this is not possible from the server with-out the use of remote events and local scripts.
How-ever if your doing this for a animated youtube video with no actual players. Yes this is possible.
It is possible to change the global camera settings using server scripts. However, it's impossible to change a player's local camera settings without RemoteEvent/RemoteFunction. If you don't have knowledge with FE scripting, you should probably find some tutorials on Youtube.
