The video_url attribute that I spoke about points to an Amazon S3 server. I don’t know what sort of presence Amazon has in Australia in terms of datacenters but that would certainly account for delays Australian users of ring.com doorbells see.
ring.com would certainly like you to get one
Which code? I doubt that you’ll ever see a legal copy of the code for the doorbell firmware or the server-side code either.
That’s the dilemma - DIY or buy. Personally I felt that going the DIY route for my video doorbell system probably would have resulted in a system that was perpetually 90% done and worked 75% of the time so I chose differently. Once things warm back up here in the states I’m going to get serious about installing some non-ring cameras to cover other areas of my property, so my security system will be at least partially DIY.
