The D Link DCS 2630L and the Netgear Arlo Q recorded movement well, while the other cameras had at least some lag and image distortion. Internet speed can affect lag, so motion is often worse on live video feeds, while recordings have fewer problems than live streams. Nighttime videos use infrared light instead of visible light, so they don't match the color or detail of daytime videos. Therefore, we assessed the brightness of the nighttime picture instead, with brighter video producing more detail. The top nighttime security camera was the Belkin NetCam HD+, which illuminated our room better than other cameras.

In terms of core performance, most reviewers give Nest Protect a thumbs up. It has only a photoelectric sensor, which normally will mean that it is more effective in detecting smoldering fires rather than fast burning ones and that's exactly the performance that Consumer Reports found when it tested the first generation model. However, the current, second generation Nest has a unique Split Spectrum sensor that's said to be more effective than the norm for photoelectric technology. However, we did not spot any rigorous testing to verify that claim, so for now, consider this to be a standard photoelectric unit. Likewise, expert testing of the CO side of things is limited. No one has rigorously tested the CO detector performance of the second generation model.
