What type of lens is best for monitoring areas like a warehouse aisle or stairwell?

In a scenario where monitoring an area such as a warehouse aisle or stairwell is required, a long-range lens is particularly beneficial. This type of lens allows for effective observation over greater distances, providing clarity and detail of objects or individuals that may be further away.

The long-range lens is designed to focus sharply on subjects that are not immediately close to the camera, making it easier to capture clear images or video in such expansive or multi-floor environments. This is crucial in areas like warehouses or stairwells where activity might occur at varying distances from the camera.

Wide-angle lenses, while effective for capturing broader scenes, can distort images at the edges and may not provide the detail needed for identifying individuals or objects at a distance. Infrared lenses are valuable in low-light conditions, but they don't necessarily enhance the viewing range. Fish-eye lenses offer a 180-degree view, which can lead to significant distortion and is less suitable when clear detail is necessary in specific areas.

Overall, the long-range lens stands out as the optimal choice due to its ability to provide detailed monitoring over greater distances in settings like a warehouse aisle or a stairwell.
