I want a Poe doorbell for greater reliability, and so I don't have to hire an electrician to change the doorbell transformer.
I want it to connect to my NVR and record either 24/7, or just when a person comes to the door.
I want the bell to connect to my phone and inform me when it is pressed.
I want it to work with chimes too. WiFi/Poe chimes ideally. I need one chime in an outbuilding and one in the main house.
Finally there is the Dahua DHI-VTO2202F-P 2MP Villa Outdoor Station which has the features you want, or the Dahua DHI-VTO2101E-P which has similar features, but with a different casing, and the DHI-VTO2111D-P-S2 (smaller camera and plastic case). The DHI-VTO2111D-WP-S1 is similar and has WiFi, as well as PoE, which makes it really easy to set up (use your phone to connect to the doorbell AP) -- the quick setup guide for this one looks really easy. This new range/platform from Dahua appears to be a winner.
- PoE powered
- Works direct with mobile app, no screen needed (i.e. just the doorbell)
- ONVIF/RTSP support
- No subscriptions or locked system
- Looks reasonable
- Priced reasonably
- High quality brand
- Local API, e.g. integrates with Home Assistant
Does not directly connect to a door chime, but supports Home Assistant, so can easily respond to button press events, e.g. trigger a chime.
This is a video review I found :
There are also videos on connecting it to a door chime, and on the DHI-VTO2101E-P.

Previously I had tried the HikVision DS-KV6113-WPE, which the latest release notes say can work in stand alone mode, and with Hik-Connect, but not at the same time, so that was a fail.
It can be added to Hik-Connect mobile app and you can view video, use the intercom, trigger door unlock etc, but I could not get it to receive call notifications when the button was pressed.
In the configuration, I can also set up the alternate schedule (Templateplan1) to call the centre (yellow) for all dates/times (instead of the indoor screen), and using the iVMS-4200 sofware I can receive the call on my computer.
So technically it can connect to mobile app (Hik-Connect), and technically work stand alone (without screen) via the iVMS-4200 software, but not both combined. Fail.
