Infrared night vision helps a surveillance camera monitor outdoor locations when natural light is insufficient. A Smart Dual Light Bullet CCTV Camera equipped with infrared illumination can capture nighttime images without relying entirely on visible lighting. Depending on the model, the camera may also activate white-light illumination to provide a different nighttime viewing mode. These functions can be valuable for monitoring corridors, perimeter fences, entrances, and outdoor equipment storage areas. Buyers should check the camera's infrared range, supported resolution, and nighttime performance before purchasing. With appropriate positioning and installation, this camera can help improve overnight monitoring for homes, offices, farms, shops, and other properties.
