One phone broadcasts camera and microphone. One or more devices receive the stream with sub-second latency. No native apps, no app stores, no account with a hardware company that might stop caring about your camera in three years.
Baby monitors are either a dedicated device with a proprietary app and a cloud account, or an old phone running software that was never meant for the job. Nursery is the third option: a page you open on whatever devices you already own.
The broadcasting phone opens its camera and microphone in the browser. Receiving devices connect directly to it, peer to peer, so the video and audio never route through a server unless your network genuinely requires a relay to get through NAT. Latency stays under a second, which is the difference between a monitor and a recording.
Nursery is an internal Locke Werks product and the source is private. It is designed to be self-hosted, so there is no service to sign up for and no camera footage sitting on somebody else's disk.
