Wide Angle C-mount Lens
Learn More About Wide Angle Lenses For C mout Cameras
C-mount cameras do not come with lenses for many reasons. Because every CCTV surveillance application is different from another, it is hard to build a camera that can adapt or meet the needs of the surveillance demands. However, c-mount cameras do not come with a lens, so that customers can choose their own lens, since they know what they are looking for from their cameras. So naturally a common question most owners of c-mount cameras ask is: "How do I get a very wide angle of view from my c-mount camera?". To capture video with a wide angle of view, you need a lens with a small mm setting. A lens with a 2mm, 2.5mm, or even 3.5mm aperture, will make a very wide shot of video. The large your lens size is the longer you will be able to see, however you will sacrifice you field-of-view. So when shopping for a c-mount camera, make sure you purchase a lens with a 2mm to 4mm rating to get a very wide angle of view.
2.0mm Is The Widest Shot Of Video For Any C-mount Camera
If you are looking for the absolute widest video shot, you need to purchase a 2.0mm fixed lens or a varifocal lens that has a 2.0mm lens setting. Any wider than this and you are looking at a lens or bullet camera with a fish-eye. This is more commonly found with the use of bullet cameras. However, you can achieve other wide angle of views by using a 3mm, 3.5mm, or even a 4mm lens. If you use our security camera lens calculator you can figure out what distance you are looking at compared to the feet you get in your field-of-view.
