I started looking into DIY video cam as a baby monitor but the general consensus seems to be that this is too important to be doing DIY and you should instead buy a cheap china baby monitor camera.

The thing is that every single baby monitor I'm looking at has a connection to the cloud and I've seen too many horror stories about hackers talking to your children via those systems. Additionally I don't want the Chinese state constantly listening in on our conversations at home for some specific reasons.

From what I can see, in my case it is either have a DIY solution just to be able to close the door to the bedroom and still see the baby on the TV while behind the door, or have no camera. Or does someone know about any local only cameras?
