Yes but the UDM-Pro-SE is a separate product from the doorbell. The Reolink doorbell does not need a separate product to function. You can just get a POE injector or POE switch from any brand, run Home Assistant on a Raspberry Pi or NUC and it'll work. The UDM acts as an NVR for your doorbell camera, you couldn't use it without it, right?
You can run UniFi console as software on any* device to manage the doorbell, which would then allow you to use Scrypted as the NVR and expose it to Home Assistant.
