Curiosity, sound etc

I have not purchased the can pan YET, but looking forward to grab one and play around. I was just curious if it makes, if any, noise when it moves. For example, is like to keep an eye on a few of my things(tools, car, etc…) and when motion is detected or if I want to free roam, will the cam be noticed due to device movement (noise wise) or anyt other type of noise?

There is a slight gear/motor sound when it’s moving.
