Frequently Asked Questions
Does zooming in reduce image quality?： No. The camera uses a true 3x optical zoom lens that changes focal length with physical glass elements. Unlike digital zoom, it retains full 4K resolution and sharp detail throughout the zoom range.
What are the benefits of PDAF autofocus?： PDAF calculates distance by comparing the phase difference of light, allowing the lens to focus instantly and precisely. This eliminates focus hunting and the blur it causes when subjects move in front of the lens.
Do I need to install software or drivers?： No. The camera is UVC-compliant and works driver-free over standard USB 3.0 / 2.0 and HDMI. It connects directly to computers, monitors, or capture devices.
