The Lumens CL510 Ceiling Document Camera is a professional-grade full HD visual presentation device engineered for ceiling-mounted overhead display in educational, corporate, legal, or technical training environments. Featuring a 1/2.8″ 3.4‑megapixel CMOS sensor and delivering 1080p video at up to 30 fps, it ensures sharply detailed real-time imaging. Its powerful 30× optical zoom with 5× digital zoom allows presenters to zoom in from wide views to close-ups of small details with clarity. Multiple output interfaces—including VGA, DVI, USB, and Ethernet—support direct connection to displays, computers, networks, or video streaming systems, with Ethernet enabling PoE to eliminate the need for a separate power source . The camera supports RTSP unicast and multicast streaming, picture-by-picture and pan/scan display modes, one-button auto-tune, image rotation in 90° increments, slide show, timestamping, and internal storage for up to 120 JPEG images. USB flash drive recording (up to 32 GB) and synchronized video archiving support flexibility in documentation. The unit supports remote control via IR remote, RS‑232, USB mouse, or web interface, and includes annotation software (Lumens Ladibug) for users on Windows and Mac . With a low profile (5.0″ × 3.4″ × 5.6″) and lightweight 1.76 lb design, the CL510 installs discretely in ceilings while remaining accessible via remote or network control. Security is enhanced through a Kensington lock slot. Lumens includes a 5‑year warranty, ensuring long-term reliability for institutional installs.
