CCTV Camera Lens Size Chart: Navigating Surveillance with 4-16 MM Lens Sizes
In the dynamic world of surveillance technology, the size of CCTV camera lenses plays a pivotal role in determining the field of view, image clarity, and overall effectiveness of a security system.
This article serves as a comprehensive guide, accompanied by a detailed chart, to help you unravel the intricacies of CCTV camera lens sizes and make informed decisions when selecting lenses for your surveillance needs.
The Importance of CCTV Camera Lens Size
Field of View (FoV)
The field of view refers to the area that a CCTV camera lens can capture. Different lens sizes result in varying FoV, impacting how much of the scene is visible in the recorded footage.
A larger lens size generally provides a narrower FoV, suitable for focusing on specific areas, while a smaller lens size offers a wider FoV, covering more expansive spaces.
Image Clarity and Detail
The size of the camera lens influences the level of detail captured in the footage. Larger lenses with higher focal lengths excel in capturing fine details over long distances.
On the other hand, smaller lenses are adept at providing a broader view but may sacrifice some level of detail, especially at a distance.
Low Light Performance
The aperture size of a camera lens, often denoted by the f-number, affects its performance in low-light conditions.
Larger aperture sizes allow more light to enter the lens, enhancing visibility in low-light environments. This consideration is crucial for applications where surveillance is necessary during nighttime or in poorly lit areas.
