I am just wondering if someone is using Hikvision doorbell.
Yes, I have the hikvision DB2 which is also sold under other brand names (laview DB1, halo, RCA).
For me, it’s connected to blue iris which then bridges motion activities to openhab. I also wired the doorbell button into a wireless sensor to trigger OH rules.
It can also send onboard PIR activities to OH via onboard ONVIF events sent through MQTT, but I’m not using this presently.
There is a massive thread on everything you need to know about this doorbell here: https://www.google.com/url?sa=t&source=web&rct=j&url=https://ipcamtalk.com/threads/new-3mp-wifi-video-doorbell.38434/&ved=2ahUKEwiT7syy3ZPqAhVcJDQIHYzyAW8QFjACegQICBAB&usg=AOvVaw3Tt44N0mRtyAxWeZe-gqiB
