Both of Ring's doorbells record video in 1080p, while the RemoBell and August Doorbell Cam record in 720p HD. August's resolution is actually 1280 x 960, but that's not quite "full" 1080p resolution. Night Mode: The video doorbells we tested take different approaches to capturing video at night. The August Doorbell cam uses motion activated LEDs to light the area in front of the camera, so it can capture colors a little better. The RemoBell and Ring's doorbells use infrared night vision to see in the dark, but the result is monochrome video. Design: Aesthetics may be a concern. After all, you're bolting this thing to the front of your house!The Ring Pro looks the most like a traditional doorbell, and Ring even includes four faceplates, so you can choose which matches your house's trim or paint one exactly the shade you like. Video Doorbells vs. Security Cameras: Video doorbells don't necessarily make great security cameras. While the apps let you choose to receive motion alerts as well as doorbell alerts, motion triggered events often resulted in video of a person or car just exiting the frame. A dedicated security camera may be a better choice if you're looking for actual security, because you can position such a camera in more places.
