In camera specifications, what does the last letter "L" refer to?

In camera specifications, the last letter "L" typically refers to "LED Illumination." This designation is often used to indicate that the camera includes built-in LED lights, which can enhance visibility in low-light conditions or be used for specific functions such as facial recognition, object tracking, or to improve image quality. LED illumination helps ensure that images captured in darker settings maintain clarity and detail, which is especially important for surveillance and monitoring applications.

The inclusion of LED illumination as part of the camera's specs highlights the importance of lighting in photography and video capture, enabling users to utilize the camera effectively across various environments. This feature is particularly advantageous in security cameras, where reliable performance is crucial.

Other options, while related to features of cameras generally, do not correspond to the designation specifically associated with the "L" in camera specifications.
