I self host my "baby monitor" with UniFi Protect on UCG-Max and a G6 Instant wireless camera. It's more work to setup, but pretty easy for a techie. It has the "turn on the app anywhere and it works" feature, and with a 2TB SSD I get a month+ of video storage. Because storage is local, it doesn't need to compress the video and I get a super clear 4K image. And I use Homebridge to expose the camera over Apple HomeKit which is a convenient and a more user friendly way to access it. And HomeKit also gives you out-of-home access with a hub. I love my setup, but I couldn't in good conscience recommend it to a non-techie friend, especially if they're sleep deprived from their infant.
But I do miss the lack of any baby-specific features like sleep tracking. It has support for crying detection, but that's it.
