Hi, don't know if this is the right section but here goes. I've been looking at smart doorbells and what I have found to date is, the Nest is a faff to install and the Ring Pro is easier because it has its own plug in chime and easy to run off a 24Vac adaptor but there seems to be more than a few who have problems with Ring. At over £200 for a doorbell you would want a good reliable system so, is there anything out there that costs less and seems just as good? Is it a case of keeping ones cash in ones pocket because all they do over and above a bog standard doorbell is give you a video and sound that can be used over your phone etc. Are they worth the cost?
