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.

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.

The doorbell ring function still worked. I recalled reading in the instructions that cautioned you should not over torque the mounting plate screws and I suspected I had done that. I removed the camera from the mounting plate a little scary–the two retaining clips on the right side are two step releases and they’re plastic and charged the camera using the micro USB port and my Nook charger. I backed the mounting screws off a bit and reinstalled the camera. Everything has worked perfectly since then and today I had a package delivered and the camera caught a video clip of the delivery perfectly!The interaction/notification through the ADT app on my iPhone is just awesome. The doorbell camera is a great addition to my ADT system. I just had ADT install the video doorbell, I have an issue with the power, my original doorbell wires went to a Niles DBI 1 doorbell interface, so when the button was pushed it would create a contact trigger with the Niles unit which would have it play its chimes throughout the house using the whole home audio speakers in each room. To get the ADT video unit to work we had to remove the Niles interface and install a transformer to run continuous power to the ADT unit. Now I don’t get the door bell to ring inside the house. I tried to hook up the Niles unit inline but that just send power to the Niles which causes the inside chimes to play all the time. What is the difference between having the ADT unit in analog or digital mode?the tech set it up in analog knowing I had a digital chime.
