That is a junk cloud based system...you will not get any good footage. You need to get a camera with a 12mm lens or a varifocal camera that you can precisely adjust. Consider a hikvision 2732F varifocal..or one of these with a 12mm lens

Can you please elaborate for me as I am a complete beginner. Does the camera you mentioned record to SD? How can i playback footage?
