Getting a good understanding of the difference between digital and optical zoom can be challenging unless you work with security cameras all the time. In this tutorial, we explain the two zoom modes that are common in surveillance equipment and their affects on image clarity.
Digital zoom uses software algorithms to magnify a selected portion of a video image, which invariably results in pixelation that diminishes clarity and detail, while optical zoom actually physically adjusts the lens to zoom in, like a telescope, preserving the image's quality.
While digital zoom stands as a budget-friendly alternative and is available on all cameras, it frequently results in grainy, pixelated images, making vital details difficult to discern. Conversely, optical zoom retains the image's integrity, adeptly capturing intricate details from afar. However, cameras with optical zoom or pan-tilt zoom carry a heftier price tag.
