What to Look for When Buying a Video DoorbellPower Requirements: Doorbells typically require 16 volts or more to work. If you have a newer house, this may not be an issue. But as we found out, older homes with more antiquated systems may not deliver enough juice. One of our test houses, which was built in 1946, was sending only about 10 volts of electricity to the existing doorbell, which wasn't enough to power the two doorbells in the roundup that lack built in batteries. After we upgraded the doorbell's circuit to a 20 volt transformer, everything worked as advertised. Most people shouldn't have to upgrade their transformers, especially with newer houses, and the two doorbells that have built in batteries don't require power from the doorbell at all. Some doorbells, like the Ring Video Doorbell 2 and the RemoBell, can run on battery power. This is incredibly helpful if your existing wiring isn't getting the job done and you don't want to upgrade the transformer. Just remember that you'll have to recharge these units regularly. Doorbell Placement: Your choice of doorbells will also depend on whether you're replacing an existing doorbell or installing a doorbell where there isn't one already. The Ring Video Doorbell 2 is the most flexible.
