Security Camera Lens, Surveillance Camera Lens, Varifocal Lens

Your security camera lens is very important.  Depending on the lens, your view of the events can be completely different.  Each lens is better for different uses, so check out the different kinds of surveillance camera lens to ensure that you make the best decision possible for your safety.
Fixed Focal Lenses : Fixed focal lenses are available with choice of iris function (manual or auto iris) and focal length (2.3 mm to 25 mm). Fixed lenses have a predetermined focal length and manual focus control.
VariFocul Lenses: We offer the largest selection of cameras with a varifocul lens in the surveillance industry. Lenses are available with adjustable zoom for a large range of focal lengths. Unlike a zoom lens, a varifocal lens does not maintain focus when zoomed. The lens at installation is set for optimum field of view. Motorized Zoom Lenses: zoom lenses are available with either manual or auto iris lens function. A motorized zoom lens keeps the viewed object in focus while varying the length of the lens.
