The DarkEye SLA lens HV0733D-6MP is the latest technological advance from Hikvision and significantly enhances Darkfighter performance to unrivalled levels. Featuring IR correction and up to 6MP esolution, the DarkEye SLA lens is available on both DarkFighter box cameras and features a consistent aperture of f/0.95 across the entire 7-33mm focal length range. It means that you can operate the camera at its large aperture at all times, and at any zoom setting, for maximum low-light performance.
