Similar product, different experience: I tried their doorbell and found it to be way underpowered once I turned on ONVIF. Huge, expanding lag between real world and camera feed. 20fps max is very oof too, even if you are going to use their protocol and software. And it doesn't work with physical chime boxes, so you have to use their plug-in chime or botch a converter together yourself.
Was really excited (trying to replace a nest doorbell) and then so, so disappointed once I got it. Their other cams might be fine but oof, the experience put me off.
Might reevaluate the "instant" part, then.
(I've been using docker for 7 years or so, and it's always some bullshit like undocumented environment variables or bullshit password limitations or broken smtp implementations or the repo just assuming you are the actual dev and giving no fucking instructions at all or the container shitting itself for no motherfucking reason at random times and you try to fix it and it goes well and then you wake up and it's restarted several times through the night...)
