CCTV Cameras

Traditional PTZ cameras often struggle to ensure that images remain bright and clear when they zoom in, especially in low light conditions. This is because the lens aperture gets smaller when operators increase the focal length, reducing the light entering the lens and thereby impacting the clarity of images.

One way to solve this issue is to adjust the size of the aperture as the focal length changes, so that a consistent amount of light can enter the lens. With Hikvision ColorVu technology, a very large fixed aperture is used in the Pro series varifocal PTZ cameras, enabling consistent light and color for imaging as the camera zooms in or out at night.
