LIFX+ color LED smart bulb review: This light bulb helps your security camera see in the dark
“Night vision” cameras—of which there are many on the market—can’t really see in the dark. What they have is a sensor that can detect light in the infrared spectrum, and most models have a small infrared LED on the front to help light up the surrounding when the sun goes down. Infrared light is invisible to our eyes, but it makes a huge difference in what the camera can pick up. The catch is that those infrared LEDs aren’t typically very powerful, which is why nighttime footage from most of these cameras looks fuzzy and muted.
