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. The Foscam C2 was the only camera we tested with no audio distortion. Built in speakers on each camera we tested, except the Y cam Indoor HDS, let you use the mobile app to talk to anyone near the camera.
