Video doorbells are doorbells that have a built-in camera to help protect your home from package theft and burglary. They are either battery-powered (wireless) or hardwired into an existing doorbell. You can receive activity alerts, talk with visitors using two-way talk, and live stream video from your smartphone.
Video doorbell camera systems can see anywhere from 5 to 50 feet in front of them. While longer distances seem better, there are some downsides. If your city or state has laws against filming sidewalks or roads, a shorter distance is better.
