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. For more information on the Box camera and
the varifocal lens that was used in this video, please visit www.cctvcamerapros.com/pro680dn28.
Thank you for watching.
