Re: To be fair to Owlet...
I suspect there are not many actual parents contributing to this topic, and don't appreciate the worry that new parents feel every time they put their babies down to sleep
Cot death is a very small risk for most families, certainly not enough to hooking your child up to a medical grade ECG machine every time it's put in a cot. But so as you don't feel guilty for not checking them every 10 minutes during their sleep for the first year of their life, particularly when you are out and leaving the duty to a baby sitter, some sort of unobtrusive and reliable monitor would good, and that's why there is a market for these sorts of things.
We don't expect these things to have FIPS 140-2 security certifications, but not being wide open to anyone if WiFi range would be a good start.
