This blog answers whether the "Z" (Zoom) in PTZ cameras always means optical zoom. It explains that while optical zoom (using lens adjustments for sharp, lossless detail) is common for "Z", some PTZ models use digital zoom (enlarging pixels, causing quality loss) instead. It breaks down the differences between the two zooms, why manufacturers might use digital zoom, and tips to check which type a PTZ camera has—helping buyers avoid misunderstandings.
