The camera remains connected with the server all the time. When a command is initiated by the owner via web or mobile app, it happens immediately. If real time is off, you rely on Scheduled Events (or a motion or time lapse event) to have the camera make contact to the server. No matter the real time is off or on, when the camera takes a photo, you receive it immediately. When Real Time is ON in the camera, it does consume more battery power.
