What does the Axis Lens Calculator provide based on focal length and target distance?

The Axis Lens Calculator is a useful tool designed to help determine the pixel density values based on the focal length of a lens and the distance to the target being observed. Pixel density, which is a critical factor in evaluating the performance of a surveillance system, indicates the level of detail that a camera can capture in relation to a given scene. By inputting specific parameters such as focal length and target distance, the calculator provides quantitative insights on how these elements influence the clarity and detail of the recorded image.

Having accurate pixel density values is essential for designers and installers of video surveillance systems because it helps ensure that the camera is suited for its intended use, whether that's monitoring a broad area or capturing fine details. This is particularly important in settings such as retail, where recognizing facial features or license plates can be essential for security and operational effectiveness.

The other options presented don't align with the primary function of the Axis Lens Calculator, as it does not focus on general camera specifications, installation recommendations, or lighting adjustments. Instead, its main strength lies in quantifying the relationship between lens characteristics and image detail, making pixel density an essential output of the calculator.
