A Security Camera is Nothing without a Good Lens

What is field of view?

Lenses come in all shapes and sizes, but one thing you’ll really need to look for is a factor called FOV, or “Field of View.” This refers to the height and width of the picture visible to your camera lens. Different applications will need different FOVs, so if your system needs flexibility, consider a varifocal camera lens that you can adjust to zoom in or out on the cctv camera’s target.

Security camera lenses and light

Another important consideration is the light condition of the camera’s placement.

If the light is consistent, like in an office space or store, the most cost-efficient option for you is a manual iris lens, which you set when you mount the camera.

For areas with natural or changing lighting, like a parking lot or loading bay, your best option is an auto iris lens. Auto iris lenses can adjust themselves accordingly, giving you a better image, in many cases, than a manual iris lens.
