The Theia Technologies CS-Mount 9 to 40mm Telephoto Day/Night Manual Iris Lens magnifies objects from far away for unobtrusive security.
The lens is designed to allow the installer to take full advantage of the high resolution of HD and multi megapixel cameras and can be used on cameras at up to 5 MP resolution, giving a crisp image from edge to edge.
The lens is IR corrected for use with true Day/Night cameras. With IR correction, light from artificial illumination focuses at the same plane as the visible light, allowing the image to remain in focus when the camera switches to night mode and. Unlike lenses without IR correction, the night image will not be out of focus when using IR illumination.
