Optical zoom is a camera feature that uses the physical movement of lenses to magnify an image without reducing its quality. Unlike digital zoom, it preserves sharpness and detail when focusing on distant objects.
For example, surveillance cameras with optical zoom can clearly capture license plates or faces from far away. This is especially useful for monitoring large areas such as parking lots, warehouses, or public spaces.
While digital zoom enlarges pixels, optical zoom adjusts the lens itself. As a result, users get clearer images and more accurate identification.
By using optical zoom, security teams enhance monitoring precision and improve threat detection.
