Video Doorbell usable as IP Camera for Gateway?

[Tony Weil]

Does anyone know of a "Video Doorbell" product that can be used as an IP Camera for use with the Pi Gateway and Snapshot URL function?

I don't have a link/answer to your question, but I've seen lots of such doorbell products on the web, amazon has tons too, but you will have to double check the IP part of it.

Also if this helps - a current camera I use does not have a readily available snapshot feature - instead it would require to make an HTTP request, which generates a JPEG on the internal storage of the camera, which then is available at a certain URL - a bit cumbersome but doable. However, I am running a MotionEye OS on a raspberryPi which captures the video stream from that camera, and also provides a simple snapshot URL which makes things a lot easier (simply request that URL from the Pi and it returns a snapshot rather than mess around with the camera itself). The result is what you can see in one of my recent blog posts.
I guess the most important thing is for whatever camera you get - to have a video stream, which can then be "snapshot-ized" by a recorder or even a Pi.
