Video doorbell and 'mechanical' chimes - UK

Hi All, Am in the UK and looking to get some clarity. I was looking to buy a video doorbell to replace my simple old non-video bell push, but I've now discovered that ~99% of the UK doorchimes run on 6-8v DC and not the 16v DC needed for the Ring doorbell. I've also been unable to find a 16v chime available for sale in the UK and so this would suggest that I am unable to do anything except have a fully wi-fi doorbell. However, I also spoke to the Ring on-line chat yesterday as I wanted to confirm that I could hardwire the Ring video doorbell to an existing mechanical chime so that I could ensure that at least one doorbell in the house was not 100% wi-fi reliant. However, they stated that if the wi-fi was down, even the hardwired mechanical chime would not operate.....suggesting that even if I did have a 16v chime it would still not operate without wi-fi.......does anyone here know if this is true or not? Whilst I've been doing my research I also spoke with a number of friends about video doorbells and a significant number of them said they had decided not to buy one because of the reliance of the door chime on the wi-fi signal. So, not having a 16V chime available for the UK market would seem to be a bit of an oversight in the Ring UK product range and perhaps an opportunity to get ahead of the competition :slight_smile: Thoughts?
