The Google Nest Doorbell was the most accurate when it came to identifying types of motion (person, animal, vehicle, or package), and reacted quickly when sending smartphone alerts and displaying live views. The image resolution is only 960×1280, which is lower than our other picks, but the picture is clear, and the low-res actually ends up being easier on your Wi-Fi network to allow for smoother streaming.

While it offers free cloud storage, you’ll only be able to access footage from the past 3 hours . If you want to keep it longer, the Nest Aware plan (starting at $8 per month or $80 per year) can store video up to 30 days, and adds in Familiar Face Detection. In addition, if you want 24/7 recording to the cloud, you’ll have to shell out $15 a month or $150 annually for the Nest Aware Plus plan.
