Without a doubt, the DoorBell Pro is a great product. The concept is good, the quality is very good and it is easy to configure and use. I had previously tested similar products and sent them back. I was not only impressed with this one, but I was thrilled with it. What is even more astonishing is that the support and service hotline work excellently. Prompt answers, friendly, very accommodating in warranty cases.
I've been using the door camera for a week, so far everything is working. I understand that a week is not a long time, but still. Nice design, lots of options. Notifications arrive quickly. So far I'm happy. Yes, and most importantly, the battery seems to last a long time. But remember that buying such devices is a lottery. Even an expensive Mercedes can break down at the most inopportune moment.
