I actually don’t really get the point of a cloud service for this. Aren’t babies usually left in situations where there’s at least one trusted adult locally available?
It's much easier to create a device<->internet connection + a smartphone<->internet connection that it is to deal with the myriad of issues that occur if you try to do local device<->smartphone connections in networks with unknown topology and quirks (e.g. ISP provider being overly conservative in their firewall presets). If that in general would be a more trivial issue you would see less cloud services.
(You would probably still a similar amount of cloud services due the increased monetization options, but this would level the playing field for local-only options.)
- most people want to build lovely structures in the cloud, as it's hard to fix bugs in software on devices
- you'd need to open up a firewall on the home router
- auth might be tricky
- can't bolt on value added "enhancements"
Many cheap baby monitors are WiFi connected. You have to haul the video unit around and keep it live to hear when it cuts out, then move back toward where WiFi coverage was good.
This won’t seem like a big deal to someone who lives in an apartment or who has a house with 7 Ubiquiti APs covering everywhere inside and out, but it is a big deal to a parent who has a single WiFi router and wants to be able to do something like pull weeds in the yard, have a conversation with the neighbor, or go to a detached garage and work on a project without having to worry about their exact WiFi coverage at every moment to check on the baby.
ox and hearth rate baby monitor definitely alert on sids. prevent, no, and that's why they are not medical devices, and wouldn't make sense to pay a randomized controlled trial to certify as one.
works? yeah. hearth stops beating, ox goes under parameter, parents get an alert.
here's the FDA statement about it https://www.accessdata.fda.gov/cdrh_docs/pdf22/K222597.pdf

So, 24/7 kinda, yeah... Realistically, the risk is relatively low I'd say, so to still stay a functioning parent with other duties (for baby or otherwise), you don't look 24/7
