My favorite part of asking any technical question is the mandatory &quot;you don&#x27;t actually want to do what you&#x27;re asking us how to do&quot; :)<p>Pretty much most of what people said in response; if the baby&#x27;s asleep and I&#x27;m cooking in the kitchen while watching a YouTube video and boiling something, it&#x27;d be nice to have a window displaying the kid in the corner so I can tell when it wakes up. Plus, it might be nice to tune in from work and watch it sleep. Plus, the wife wants one.<p>Given that dedicated hardware ones are expensive, I&#x27;d like to try it with one of the old phones we have laying around - if I come to agree with you that it&#x27;s unnecessary, I won&#x27;t have wasted $200 on something that really has no other purpose.
