I do have a separate PoE camera with a larger IMX347 1/1.8" sensor as well, running PoE to my doorbell is a nono lol.
The Reolink Doorbell quality is fine if you have sufficient lights but still has it's limitation due to its form factor
All Video DBs have their small form factor limits.
ReoLink's lack of WDR & BLC is it's major flaw IMO. Anyone with a porch where the DB is mounted in and has the sun in the background will have to chose which one of the two to tune in the best video quality. I chose the porch and capture any walking up to the porch with my other camera(s)
But I do agree with flynreelow, out of the two (Hikvision DB) and (ReoLink's DB), ReoLink is the winner. We both had our Hiks for several years and they served us well. Presently I am running the WiFi version of the ReoLink without any issues.
