CCTV camera varifocal lenses should be your first choice when considering driveway/corridor security. The great advantage of these is that you can adjust how far away you want your shot (zoom), as well as how close (focus) while you are installing them. This can be really helpful if you’re not exactly sure what type of shot to take at this point. You can zoom in enough to capture a license plate, but still get a wide enough shot of the entire yard without having to actually move the mounting location of the camera.
I have been building out a machine vision set-up for measuring dimensions and wanted to chat about optics. One of the primary advantages of a C Mount Telecentric Lens is eliminating perspective errors; therefore, an object's size will remain the same as the object moves away from or closer to the lens (within reasonable limits) - this is very important in metrology. C Mounts are a standard mounting interface used with industrial cameras, eliminating any complication of integrating them into your machine vision system; however, be aware that the lens diameter must be greater than the object’s size for proper function. Has anyone experienced any trouble with getting adequate lighting for using these lenses?
