I currently use Frigate as an NVR for my outside cameras. I would like something that integrates with that. I really just care that it is fully local. I don’t want a chance of someone on the internet being able to access a camera in my baby’s bedroom.
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
I too have a tp-link tapo indoor camera with said hacs component. I have set alerts for sound and movement, both work well, it need some tuning tough, like mic sensitivity…
For live video feed I use a webrtc camera from hacs as it has much better latency.
As a child monitor it works really well.
