CctvCamera --> Like RE(old). If you want to do a game like that, this is your camera ^.^
FreeLookCameraRig --> A very strange camera… It would be usefull if it was precise and if it be more like FPS camera.
HandheldCamera --> A zoom camera. Useful for a Sniper (or something like that)
Multiporpose --> Not bad at all… It just need a few adjustments…
