As the smart home expert here at Tom's Guide, it's not a surprise that my house is jam-packed with many of the best security cameras. A Ring Battery Doorbell Pro guards my street-facing front door for a wide angle of my entryway and side yard. Step around my property and you'll find that my back door is fair game for all of my testing. This is where I install many of the best video doorbells and smart locks.
