The JVC VN-H257U Full HD SuperLolux Network Security Camera with 3-9mm Lens (Indoor) is a mini-dome camera with vandal protection. Featuring a 1/3” CMOS image sensor, the indoor camera delivers high-quality images at a resolution up to 1080p HD at 30 fps. The integrated 3x zoom lens features a focal length range of 3-9mm and is suitable for wide area surveillance.

A minimum illumination of 0.06 lux for B&W imagery makes the camera suitable for low-light surveillance. Equipped with automatic switching IR cut filter mechanism, the True Day/Night camera offers image with rich color during daytime, and B&W imagery with high visibility at night. The built-in CLVI (Clear Logic Video Intelligence) offers wide dynamic performance and anti-fog capability. ONVIF / PSIA protocols are supported
