While August's doorbell doesn't have the highest resolution among the cameras we tested, the footage was clear enough that we could see people's faces, and we liked that its spotlight helped illuminate whoever was coming to the door at night. Because August's product looks the least like a traditional doorbell, visitors sometimes didn't know to press the device; they just knocked on our door instead.
