  2. Great insights on the role of video technology in education! I’d like to add that using a 4K PTZ camera for teaching can truly transform the classroom experience. The ultra-high-definition resolution ensures students don’t miss any detail, whether in a physical or virtual setting. Plus, the pan-tilt-zoom features offer flexible coverage — ideal for interactive lectures, demonstrations, and hybrid learning environments. It’s a smart investment for schools and institutions aiming to enhance their remote teaching quality and in-class engagement.
