What is Telephoto Lens?
A telephoto lens in the context of Yealink refers to a type of camera lens designed to provide a narrow field of view with a longer focal length, allowing the camera to zoom in on distant subjects while maintaining high image quality. Telephoto lenses are commonly used in conference cameras to capture clear and detailed images of speakers or objects from across a room, even in large or long meeting spaces.
Key Features of a Telephoto Lens (Yealink)
1. Longer Focal Length
· A telephoto lens has a longer focal length compared to standard lenses, enabling it to magnify distant objects without distortion.
· Ideal for capturing close-up shots of speakers or presentation details from the back of a large meeting room.
2. High Optical Zoom Capability
· Supports optical zoom (without loss of quality), allowing the camera to zoom in and focus on participants seated far from the camera.
· Some Yealink PTZ (Pan-Tilt-Zoom) cameras, such as the UVC86 and UVC84, are equipped with telephoto lenses for enhanced zoom performance.
3. Auto-Focus and Tracking
· The telephoto lens works in combination with AI-driven auto-framing and speaker tracking to keep the subject in focus even as they move.
· Ensures that the active speaker is always centered and clearly visible.
4. Enhanced Image Clarity
· Maintains high resolution and image quality even when zoomed in, ensuring that facial expressions and presentation details are visible.
· Reduces noise and distortion in low-light conditions.
5. Wide Compatibility with Yealink Products
