Be careful of what camera you get. My wife was breast feeding our child and people started talking to her. It was an “Amcrest” camera. Amcrest is actually a Chinese company and their firmware has holes the size of the Grand Canyon. If you confine it to your local network it would probably be fine but I just wanted to give you a heads up to DYOR on the security offered by each option.

I have all reolink cameras. I put them in a separate vlan with no internet access or DNS just LAN access. They are by far my favourite and already have tight integration support in home assistant.

I have two dcs-6100h for 9€ each that work just fine locally. Good ir night vision, very sensitiv mic and USB powered for trips.

I'm here for suggestions. Been using a xiaomi for a year but getting the thing configured on the go is a freaking pain.

I have Frigate set up with an Amcrest IP2M. I ended up buying a second wifi AP because my 2.4GHz was really clogged up after turning it on (probably related to a bunch of other stuff already on the same network).

It "phones home" a lot so I put it on a separate vlan and disabled internet access for it.

I tried and there is a noticeable delay / lag when using a wifi camera. I recommend using a real baby cam with a dedicated RF link to the base station like those made by Infant Optics. If u want to add a wifi based one as a supplement/ to feed the NVR, check out wyze v1 cams with the RTSP firmware.

We use reolink E1 cameras, and they work pretty well, not perfect. No sound alarm, and depending on the E1 vs. E1 Zoom vs. E1 Pro have different connectivity. But they are fine.

I don't have any but I've seen reolink mentioned a lot, cheaper would be tapo camera (what I have), I know some tapo have baby cry alert but don't know if this function works with hacs component. For Tapo, once setup inside app you can block internet access to the camera threw your router or else. https://github.com/JurajNyiri/HomeAssistant-Tapo-Control

FYI: Babycam manufacturers claim you shouldn't use IP cameras because they're not as reliable as their products. I think that mostly applies to the reliable triggering on sound (if the baby cries).
