HKSV Multiuser (Multi-Home) Doorbell

[mgoeller]

Hi

I want to build a multi home HomeKit secure video doorbell with the following features:

• can be paired in 3 separate Apple Homes
• has 3 separate buttons for ringing at one of each homes
• video including HKSV
• two way audio

I was thinking of buying a Dahua VTO4202F-X modular outdoor unit, see here.

If I then one RPis or Mac Mini per home (3x in total), with each a scrypted instance running, could I achieve this? I am mainly worried about simultaneous streams. How is Scrypted working? The camera provides two streams, of which only one is 1080p. Ideally I would grab that with all 3x RPi's in parallel, and then let each Pi do the transcoding work for the Home users, when a stream is requested.

I ran a somewhat similar concept once 2 years ago, with a single RPi, a single USB Camera providing one stream via v4l2, that is then copied to a virtual device with v4l2loopback for every requested stream.

Thank you!
