Stick up cam making strange "clicking" or "banging" noise

While I am watching my stick up cam, occasionally I hear a noise like a click, or a pop or something. It is actually quite loud. I thought it was just the audio stream, but the physical camera is actually making a noise! This really sucks, because it actually wakes up my 3 month old if he is not deeply asleep. Makes it a gamble to check up on him with the cam…

If it is a single “click”, you are probably hearing the IR Cut Filter moving into place. This is a physical filter that moves into place to provide enhanced low light vision. Pretty much every high-end camera uses them.
