I don't bring my phone with me when I'm going to shower or change clothes. If I do, I can place it face down and even place something on top of the rear camera if I'm afraid of capturing something other than my ceiling.

This Amazon device either needs to be left alone to capture/not capture whatever it is going to or it serves no purpose at all. I'm not going to turn it around or cover it every time I enter my bedroom. If I did, then the value proposition falls significantly.
