CCTV Camera Lens Comparison using Sample Surveillance Video
This video compares various sizes of CCTV camera lenses to show the difference in the angle of view and zoom depth that each lens provides. The following lenses where used to make these sample surveillance videos: 2.8-12mm, 6-60mm, and 5-100mm. Videos were captured using the following lens settings to compare the angle zoom level that each provide side-by-side: 2.8mm, 6mm, 12mm, 60mm, and 100mm. We believe that real sample video captured by actual security cameras will show customers the different much better than a CCTV lens chart.

Video Transcript
In this video, I will compare 5 different lens settings using a PRO-680DN box style CCTV camera.
The purpose is to provide a visual demonstration that will help educate consumers on how different lens sizes affect the angle and depth of view of security cameras.
On this screen is a side-by-side comparison of a 2.8, 6, 12, 60, and 100mm lens using the same CCTV security camera. The position of where the camera was mounted in each video is the same. The only different is the lens size that is used in each video.
The dumpster that is in each of the camera views is exactly 100 feet away from where the camera is mounted.
You can see how the 2.8mm provides the widest field of view but the dumpster appears furthest away.
Something that is important to mention is that I stopped at different distances in front of the camera in the videos where I am walking closer. In the 2.8mm video, I stop 8 feet in front of the camera.
In the 6mm video, I stop 13 feet in front of the camera.
And in the 12mm video I stop 16 feet in front of the camera.
Obvisouly the 60mm and 100mm views zoom in too much for it to make sense for me to walk closer to the camera.
In the 100mm view, the view is so zoomed in, that my entire body can not even fit in the field of view, but you can read the text on the dumpster sign very clearly.
