However, 4K video cameras are usually more expensive and require more storage space and bandwidth.

Night Vision

Night vision is another essential feature of a security camera, as many incidents occur at night. Here are the two main aspects of night vision:

Infrared Night Vision: Most security cameras come equipped with infrared (IR) LEDs, which allow them to capture clear black-and-white images in complete darkness. The effective range of infrared night vision typically varies from 30 to 100 feet, depending on the camera’s model and quality.

Low-Light Performance: Some high-end video cameras offer excellent low-light performance, providing color images even in dim lighting conditions. These cameras usually employ advanced sensors and image processing technologies to deliver clear footage when lighting is poor.

Security Cameras Field of View

The field of view (FOV) of a security camera determines how much area the camera can cover. FOV is typically categorized into normal, wide-angle, and ultra-wide-angle lenses.

Normal Lenses: These lenses provide a standard field of view, typically around 45 to 60 degrees. They are suitable for focusing on specific areas where detail is crucial, such as entryways or hallways. Normal lenses offer minimal distortion and provide a natural perspective.

Wide-Angle Lenses: These lenses provide a broader view of the area being monitored, typically around 60 to 110 degrees. They are ideal for covering large spaces like living rooms, backyards, or parking lots. Wide-angle lenses help reduce the number of security cameras needed to cover a large area, but they may introduce some distortion at the edges.

Ultra-Wide-Angle Lenses: These lenses offer an even wider view, often covering up to 180 degrees. They are perfect for monitoring expansive areas with a single video camera. However, ultra-wide-angle lenses can suffer from significant distortion, making objects at the edges appear stretched or skewed.
