CCTV 101: Camera Lenses Compared
Ғылым және технология
If you're new to CCTV cameras, you might think that all camera lenses are the same... but they're not. With several focal lengths to choose from, selecting the right lens can be a daunting task.
In this episode of CCTV 101, we'll compare different focal lengths of standard CCTV lenses to help you choose the best lens for your application.
For this video, we mounted six of our EX-SDI BZ series bullet cameras to a tripod and set them up in four different scenes. Each camera is set to a different focal length, ranging from an ultra-wide-angle 1.7mm lens- all the way up to a telephoto 50mm lens.

Wow! Thak you for your visualization. Now IEC 62676 standard gives the following numbers for D.O.R.I zones: Detection of people: 8 pixels per foot, observation 19 ppf, recognition of known people 38ppf, identification 76 ppf. For dori calculation I use jvsg lens calc. And your video gives quite a visualization of different lenses.
