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.

If you do, however, try to buy from a reputable manufacturer, and keep the firmware up to date all the time.

Although this is lower than other cameras in our buying guide, many of us don't really need best in class 4K recording on a security camera especially if you're trying to transmit that kind of data via 4G.
