This video demonstrates the variable range of view and zoom of a 2.8- to 12-millimeter vocal lens using a Box security camera from CCTV Camera Pros. On the left screen, we have the lens adjusted to the 2.8-millimeter setting which is the widest view. The video on the right displays the lens adjusted to the 12-millimeter setting, which is the most narrow and zoomed-in setting. The garbage dumpster in the background is exactly 100 feet away from where the camera is mounted. In the 2.8-millimeter video, the man stops eight feet in front of the camera. In the 12-millimeter video, the man stops 16 feet in front of the camera.

Using a camera with a 2.8- to 12-millimeter varifocal lens, security installers have the flexibility to adjust the lens to any angle of view within that range. This video shows the extreme minimum and maximum that this lens is capable of. In addition to being available on Box-style CCTV cameras like the ones used in these videos, the 2.8- to 12-millimeter varifocal lens is extremely popular for all types of CCTV and network IP security cameras.
