For example, photoelectric sensors do better with smoldering fires that grow slowly and produce a lot of smoke while ionization alarms are better for detecting fast growing, flaming fires. UL is not alone in this recommendation; many other fire
safety organizations make the same suggestion. If you
want more information on smoke detectors, we recommend checking out the National Fire Protection Association's helpful guide, "Safety Messages About Smoke Alarms. "How We TestedEase of UseOur testing team built a custom apparatus designed specifically to analyze each smoke alarm’s detection capabilities. It was placed in the center of a room measuring 25. 33 x 18. 83 feet. We mounted and hardwired each of the detectors to the apparatus and noted how long it took to install each one using the included manufacturer instructions. After connecting each alarm to a Wi Fi network, we installed its associated mobile app on a smartphone. We evaluated how easy each app is to use and tested how long it takes for notifications to arrive on your mobile device when there is an emergency. We also assessed how well each device connects to third party smart home automation systems.

that includes a couple of seconds of video before the motion is detected, which means the device is more likely to capture a usable image. While August's doorbell doesn't have the highest resolution among the cameras we tested, the footage was clear enough that we could see people's faces, and we liked that its spotlight helped illuminate whoever was coming to the door at night.
