So, you don’t need a hard wired doorbell connection to install. Ring Doorbells are durable. They are all certified for outdoor use and operate in temperatures from 5 degrees Fahrenheit to 120 degrees Fahrenheit. They all come with motion detection, night vision, and two way talk. One of the most significant negatives with the Ring Doorbells is the lackluster battery life. Ring says that they average 12 months of battery life. However, when tested, they only offered a little over two months of battery performance. Read our full review of Ring here. Additionally, the installation and connection processes are extremely easy. You can install the doorbell with just a screwdriver. And, the connection setup can be performed using the provided QR code that reads the information and connects to your Wi Fi network without you having to do anything other than capturing the QR code.
