Super-Wide Angle Lens: The 2.8 mm Board Lens provides an extra-wide field of view, which is ideally suited for most installations.
A 6mm lens will bring you closer to the action than a wide angle lens, and when used with an IR Camera, it will not cause from the IR light, as a wide angle lens will.
All IR Camera manufacturers recommend using a 2.8mm Standard Board Lens or higher for use with their IR Cameras.
Easy to Install: Replacement lens easily threads in after removal of the previous lens is removed.
