What type of lens is ideal for capturing wide-angle views in surveillance?

• A. Telephoto lens
• B. Standard lens
• C. Wide-angle lens
• D. Macro lens

Answer: (C)

A wide-angle lens is specifically designed to capture a broader field of view compared to other types of lenses. This capability makes it particularly advantageous for surveillance applications where monitoring a large area is crucial. For instance, in environments such as parking lots, retail spaces, or public areas, having a wide-angle lens allows for the coverage of more space within a single shot. This means that fewer cameras are needed to achieve substantial surveillance, thereby enhancing efficiency in the monitoring setup.

In contrast, a telephoto lens focuses on distant subjects and provides a narrow field of view, making it less suitable for capturing expansive scenes. A standard lens offers moderate field coverage that may not be sufficient for wide-area surveillance. Meanwhile, a macro lens is designed for close-up shots of small subjects and is not intended for wide-area coverage at all. Thus, the wide-angle lens stands out as the best choice for scenarios requiring extensive surveillance coverage.
