>> I recently got a baby monitor ... no security implications.
There’s one somewhere near me that broadcasts crystal clear audio on 49.990MHz - right smack on the edge of the 6 metre band in very crisp 15khz wide FM. This audio quality beats all my local ham radio buddies. I can hear a pin drop in their house.
I’ve no idea who’s house, briefly before the pandemic i made a reasonable effort to track down the house and let them know, it’s not a house in my street, no one has the young children that can be heard.
Every time I’m on 6m i always see it on my band scope, 20db over.
I don't recommend you do it, but engineer in me is trying to find technical solutions to all problems. If you can hear them presumably they can hear you on the same frequency. So you could get in contact by broadcasting on the same frequency. You can already hear them on the radio, so if they hear you on a child monitor that would be a weird-but-functional walkie talkie setup.
Depending on where you are, it's possible that stress from knowing that their child monitor is unsecured is much higher than the risk of anyone within broadcast range abusing the vulnerability. Moreover, it's possible that whatever they replace the device with will have more significant problems to worry about. For example cloud vulnerable to the whole world instead of enthusiasts with radios in a small local area.
