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.

Sleek, upscale and supremely comfortable
Size: 9, Color: Cognac
I did not know that Marc Joseph makes hands free slip ins. I own four pair of Skechers, and I thought they were the only game in town. I decided that I wanted a pair of business casual pair of wingtips. I already own two pair of Skechers Mark Nason wingtips in blue and black nubuck, so I bought a pair of their cognac colored. Perfectly fine shoes, but when they arrived, I didn't like the color, so the search was on! I found these cognac-colored Mark Joseph's and hands down, they fit the bill for what I was looking for! I actually bought two more pair of Skechers in the brown family in the same oxford, elastic lace style: One pair of another style of their Mark Nason line and one pair of their Garza line. So now I am comparing three pair of Skechers to the Marc Joseph's. Obsessive, I know :). Luckily, I have a Skechers store near me for easy returns. The look I was going for is a sleek, business casual that I could dress up or down. Three things that I love about the Marc Joseph's are the beautiful cognac finish: the white yet lower profile soles and the more formal, narrower toe style. The MJ's nailed it with the color. They have a slightly darker, more lustrous and glossier look than the others. The color alone looks classier and pairs well with black pants which I wear for work almost every day. The white soles are exactly what I was looking for. The visible rise is probably about a third of the thickness of the others and are a much more subtle, classier look. They offset the cognac color nicely but are not that in your face, sneaker looking, thick white sole. When I was comparing them to the others right out of the box, I thought they would be too narrow and tight because they looked sleeker and narrower than the others. But they fit perfectly and were very comfortable right out of the box. Upon closer inspection and comparison, I realized the narrower, sleeker look is because the eyelets for the elastic shoelaces are closer together that give the illusion that the shoe is narrower. They compensate for what might create a tighter fit across the top of your foot with two stretchy "gores" they are called on either side of the upper part. The "slits" are nicely finished, and you can't see the stretchy part and add a nice design touch to the shoe. But between them and the elastic shoelaces, they must stretch just enough to make them extremely comfortable across the top. So, if you have a high instep/arch, they should accommodate it nicely. Last but not least, they are very comfortable shoes. I wear a size 8 1/2 to 9 and my foot is slightly on the wide side. I bought the size 9's and they fit perfectly. If you are between sizes or have wider feet, you may want to size up a half size. Because the Skechers have much thicker soles, they might be slightly more cushioned, but the MJ's are cushioned more than enough for my purposes and very comfortable. Plus, they actually just feel better on my feet. I can't speak to how durable they will be as I just got them, but so far, so good. So, there you have it. I rely on other people's reviews a lot when buying online, and especially for shoes. I know it's always a crap shoot, particularly when buying shoes online, so I hope this review helps. Everybody's feet are different, but I highly recommend these.
