CCTV Surveillance Camera Lens Size Angle of View Comparison Video

http://cctvcamerapros.com/680dn - This video compares the angle of view and zoom levels of various lens sizes using a CCTV surveillance camera, the PRO-680DN. A PRO-680DN box style CCTV camera with a 1/3 inch Sony image sensor was used to capture all of the surveillance video footage. The following lens sizes were used: 2.8mm, 6mm, 12mm, 60mm, and 100mm. The dumpster in each video is located 100 feet away from where the camera is mounted. The man in the video approaches the camera at different distances in the demo. The man stops at 8 feet in front of the camera in the 2.8mm video, 13 feet in the 6mm video, and 16 feet in the 12mm demo. These lens settings were chosen because they demonstrate the various angles of view and zoom depth that can be achieved with some of the most popular vari-focal lenses available on CCTV security cameras. The most common vari-focal lens sizes on CCTV cameras is 2.8-12mm, 3.5-8mm, 6-60mm, and 5-100mm. These lens options are all available on the PRO-680DN camera from CCTV Camera Pros.
