Still... my thinking is, I'd rather a crappy baby monitor than a badly-secured device connected to wifi, and by extension, the whole world.

We do actually have a spare camera we sometimes take away, that works on Wi-Fi. I accidentally left it once at my parent's place, then travelled back home overseas. I got a notification of my baby crying desolately as I got off the plane. Turns out it was my family arguing something in the room where my daughter was staying, and the camera somehow switched itself back on. It was freaky!
