Editor's Pick: If you have a large yard and want coverage for both the front and back doors, the 10 channels let you connect all your cameras at once. The 4K picture stays clear when you zoom in on faces and license plates, and you can still make out outlines at night. The built-in 1TB hard drive means you don't need to buy a separate memory card for recording. When someone passes in front of a camera, it can trigger the siren and two-way talk, so you can speak to whoever is at your door through your phone even when you're away.
