Is the camera somehow always on?

If you’re referring to Live Photos on iPhone devices, then the camera is always on while the Camera app is open since that would be necessary for you to be able to compose your photo on the screen. Live Photos can easily just keep the last few seconds in memory and use that once the capture button is pressed.
