Seeing in the dark: How home security camera night vision works

Here is a 188-word summary of the key points from the article: Home security cameras often need night vision capabilities to effectively monitor properties after dark. There are several common types of night vision technology used in home security cameras: Standard infrared (IR) night vision uses IR LEDs to illuminate the scene, capturing black-and-white footage. It's reliable, cost-effective, and discreet, but has limited range and reduced visual detail. Full-color night vision uses low-light sensors and advanced image processing to maintain color in dim conditions. This provides better identification of people and objects, but requires some ambient light to function. Spotlight-enhanced night vision uses built-in lights to brightly illuminate the scene, enabling full-color video even in total darkness. This offers consistent, high-quality footage, but the lights can be disruptive and consume more power. The ideal night vision mode depends on the camera's placement and the lighting conditions. IR is good for discreet, indoor monitoring, while color night vision and spotlight modes excel in darker outdoor areas where maximum detail is needed. Matching the technology to the environment is key for effective home security.
