That is really strange. So it’s there in the US site but on the UK site only the black option is shown.
Yes, I know it's been a few days since this post, but here in Germany, you can still easily buy
both the black and white models. Both the PoE and Wi-Fi versions. You can buy them directly from Reolink,
on Amazon, or from various other retailers.
The prices on Amazon are currently - as of now:
Reolink PoE Doorbell Black = € 99,99
Reolink PoE Doorbell White = 119,99
Reolink Wifi Doorbell Black = € 115,53
Reolink Wifi Doorbell White = € 115,53
By the way: Reolink itself (Reolink Official EU) is selling the black PoE or Wi-Fi model again on eBay as refurbished for € 71.09. Here's the condition description – the original German one:
Optisch: Neuwertiger Zustand ohne Gebrauchsspuren.
Technisch: Einwandfrei, der Artikel ist zu 100% funktionsfähig.
Gratis Versand & Rückversand.
I'm actually considering buying another refurbished Reolink Doorbell as a backup while they're still available.

I would actually prefer to stick with Dahua and buy the new
Dahua DB41AB Doorbell, but without ONVIF it doesn't make sense for me. I'm still wondering if it was intentional on Dahua's part that they omitted ONVIF from the DB41AB Doorbell, or if it might be added via a firmware update.
