Add a high-resolution streaming and tracking camera to your classroom, house of worship, or conference room for remote meetings with software such as Skype, Microsoft Teams, or Zoom with the gray Link 4K SDI/HDMI/USB/IP PTZ Camera with 12x Optical Zoom from PTZOptics. The Link 4K camera features the same 4K capture resolutions up to UHD 4K60 via IP and HDMI or up to 1080p60 over 3G-SDI, and it adds support for Dante AV-H audio and video routing.

The Link 4K features auto-tracking for presentations where your subject moves around the room, great for education, how-to, and corporate environments without the need for an operator. Its wide dynamic range, 3D noise reduction, and handy Dante AV-H workflow capabilities provide a sharp, consistent image, even in low light.

The camera's features include a 1/2.5" 4K CMOS 8.51MP sensor for crisp imagery. The built-in zoom lens has an optical zoom range of 12x, and you can zoom in further with up to 16x digital zoom. With 255 programmable preset positions via serial, you can set the camera to rapidly move between positions using IP, RS-232, or RS-485 with separately available controllers, or by using IR control with the included remote. It also features a tally light, and it is photo booth capable. The video output is compressed using H.265, H.264, or MJPEG formats, and you can transmit up to two simultaneous streams using Dante AV-H, SRT, RTSP, and RTMP protocols.

The camera supports external audio input via a 3.5mm stereo line-level jack for embedding audio into your stream and a 3.5mm audio output. Power is provided by the included AC adapter or via PoE (Power-over-Ethernet) on a supported network.

Dante AV-H Support
Dante AV-H brings device interoperability and the power of Dante to H.26x endpoints. With Dante AV-H, all video and audio routing, configuration, and management of devices is done with one easy-to-use platform. Dante AV-H adds Dante audio to video devices that are independently routable and compatible with thousands of Dante products.

Connectivity Features
Every Link 4K camera features SDI, HDMI, USB, and IP output for unparalleled performance and versatility. Using technology by Dante, the Link 4K can provide 1080p60 resolution over Dante AV-H, as well as SDI.

PTZ and Tracking Movement
The Link 4K's auto-tracking can lock onto a specific person, even while other people are in frame. Users can switch between on-stage presenters with the click of a button. The Link 4K can track subjects up to 300' away.

 

In addition to the Link 4K's auto-tracking features, users will also have access to the latest Web UI, updated to provide everything you need in one simple menu. Almost every feature in the Web UI has a tutorial function, perfect for novice producers navigating the settings for the first time.

Control Options
Users can control Link 4K cameras using video production software such as OBS, Livestream Studio, Wirecast, vMix, mimoLive, or Tricaster, or via a hardware joystick controller such as a PTZOptics IP joystick, serial joystick, or the SuperJoy. The options for camera control are endless, allowing you to take charge of your camera in a way that fits your workflow.

 

Link 4K cameras can be controlled remotely from anywhere in the world using a variety of tools, including NDI and cloud-based software such as Zoom. Users can also live stream directly to content delivery networks such as Facebook and YouTube.

Multiple Mounting Options
Mount the Link 4K camera above, below, or beside the action using optional wall or ceiling mounts to capture the ideal view every time. The Link 4K's automatic video inversion feature senses the camera's orientation and saves time on installation and setup.

Amazing product !
Size: 1.7 Fl Oz, Color: White, Size: 1.7 Fl Oz, Color: White
This scar gel is amazing! Feels wonderful on your skin. Helps reduce friction from rubbing your skin, which plastic surgeon encouraged me to do to my scars. He said it helped with healing. I can already vouch for silicone as far as helping to reduce the appearance of scars as I have many from surgery. Most of the scarring is almost invisible now. I have tried many other types of products but this is the best I have tried and will continue using. Good size and great price.

Surprised.
Size: 1.7 Fl Oz, Color: White
Okay surprised this is working so well, as based on the packaging the legitimacy felt low with weird spacing and typos. That said… it seems to be working? I prefer scar tape but have a few spots that it’s tricky to keep on and this seems to working great for that. I generally have pretty sensitive skin and thus far this isn’t irritating at all and it is helping to further fade surgical scars. It also does seem like a pretty good value at this price point.

A Dazzling Deep Dive into Power, Fashion, and Iconic Style
Format: Hardcover
Beyoncé: All the Songs – The Story Behind Every Track is far more than a music companion—it’s a fascinating exploration of how sound, image, and identity merge into one of the most powerful artistic brands of our time. What truly elevates this book is how vividly it connects Beyoncé’s music to her visual language—especially her unforgettable, often bold and fetish-inspired costumes. Throughout her career, Beyoncé has used clothing not just as decoration, but as an extension of control, power, and persona. The book highlights how her stage and visual identities are built around meticulously designed outfits—form-fitting bodysuits, high-gloss materials, thigh-high boots, and sculpted silhouettes that emphasize strength and precision. These looks are not accidental; they are engineered to reinforce themes of dominance, transformation, and self-possession. There’s a striking duality in many of her costumes—what some might call “fetishistic” elements like latex-like finishes, corsetry, metallic textures, and skin-tight designs are always balanced with elegance and authority. This aligns with her broader artistic identity, often described as combining “the duality between being a woman and a warrior”. Her wardrobe becomes armor, performance tool, and statement all at once. The book also captures how her visual storytelling evolves with each era. From the coordinated, handcrafted looks of Destiny’s Child to the high-fashion collaborations with houses like Versace, Balenciaga, and Givenchy, her style continuously pushes boundaries while remaining purposeful. In large-scale performances, her costumes are part of a fully orchestrated spectacle, with multiple transformations reinforcing the narrative of each song. What makes this book so compelling is that it doesn’t just document songs—it reveals the architecture behind Beyoncé’s entire artistic universe. The costumes, in particular, stand out as a language of their own: controlled, provocative, empowering, and meticulously crafted. Five stars—an essential, visually rich, and intellectually engaging tribute to one of the most iconic artists of our time.
