Dell's new Pro 7 webcam captures 4K video at up to 60fps and adds Windows Hello support, presence detection, and dual beam-forming microphones that reviewers say outperform typical webcam audio. Priced at $199.99, it competes directly with premium rivals like the Logitech MX Brio and Insta360 Link 2 4K.
Dell has launched the Pro 5 (WB526), a compact 2K QHD webcam aimed at office workers, featuring a Sony sensor, 78-degree field of view, autofocus, and a physical lens shutter. The device supports Windows Hello, includes an anti-theft cable lock, and offers AI-driven features like auto-framing and face tracking, alongside a built-in microphone. It's priced at $119.99, currently discounted to $114.99.
A developer released Laser Graffiti, a Show HN project that pairs a webcam and projector so anyone can draw on a wall using a handheld laser pointer. The software tracks the laser dot and projects effects like glowing neon trails, dripping ink, or spinning 3D shapes over the strokes in real time. The creator says the project was inspired by an older video of artists laser-tagging buildings with projectors.
An engineer spent two weeks pointing an AI coding agent, Claude Opus 5, at the firmware and update tools of everyday USB peripherals—a microphone, a webcam, and a key light. The agent extracted a full command shell from the microphone, found a way to disable the webcam's recording LED while it still captures video, and discovered the key light accepts unauthenticated memory writes from any device on the same WiFi network.
