Video doorbells have come a long way in the past couple of years and I am definitely a fan. I am currently using Skybell and it has been fantastic. It has helped up in both extremely hot and cold temperatures, excellent picture, great motion detection, I can adjust the lighting color, and best of all, no monthly fee. I really like the ease-of-use of the app and haven’t had any issues. It is easy to save a video to you phone.
My friends are currently using Ring which is what I believe the most popular brand right now however, they are paying a low monthly fee. They have nothing but good things to say about the ring video doorbell.
