Protect does more for the same price. What to look for in a smart smoke detectorFire and smoke detection
sensors. All smoke detectors use one of two types of sensors to detect fires. Ionization type sensors are best at detecting fast burning fires, while photoelectric sensors are generally better at alerting you about smouldering, or slow burning fires. You should have both types of alarms in your house. Smoke alarms such as the Nest Protect are designed to pick up both types of fires.

Wirecutter does not test the smoke alarm, and hence its evaluation isn't relied on in making our selection. That said, based on their own research, Doug

audio lets you talk to someone at the doorway with about a second of lag. I got to politely dismiss a door to door salesperson from the comfort of my bed — every smart home owner's dream.

Nest Aware streams continuous video to Nest's servers, and at the top resolution of 1600 x 1200, you could be facing 150GB to 600GB of uploads per month. Nest is up front about this, and suggests reducing the video quality to medium 1152 x 864 or low 512 x 384, or using the schedule feature to turn the camera on and off so that it's not uploading continuously.
