As CCTV cameras can now capture even higher picture resolutions through the use of HD sensor technology and advanced processing, the lenses also need to have an optical resolution that allows the camera to work at its optimal point.This range of Super Resolution (SR) megapixel lenses is designed to provide improved image resolution and sharpness, and better depth of field while avoiding the diffraction issues which can occur with megapixel sensors.They provide long and reliable operation with no maintenance. Comprising varifocal and fixed-focus types, the lenses range from wide-angle to telephoto to cover virtually all applications in CCTV observation systems.
