Aside from overall daytime video quality, we also looked at each camera's picture clarity. Predictably, higher resolution cameras yielded the best results in this test, with 1080p cameras showing greater detail than 720p models. The Flir FX, D Link DCS 2630L and Netgear Arlo Q had the clearest video among 1080p cameras, while the Belkin NetCam HD+ was the best among 720p cameras. We concluded testing by evaluating how well each camera handled motion. 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. AudioOur audio tests took a simple approach:we listened for loud, understandable audio. Some cameras were loud but the audio was distorted, while others cameras lacked distortion but were too quiet, making it harder to hear activity.
