HDVS-300 Soft Codec Conferencing System


The AT-UHD-HDVS-300-KIT is part of the Atlona HDVS Series of HDBaseT extenders with AV switching and scaling, plus automatic display control and automatic input selection. See below for a complete listing of transmitters, receivers, and extender kits.


The AT-HDVS-CAM is the recommended PTZ conferencing camera for use with the AT-UHD-HDVS-300-KIT. Both products can be purchased together as the AT-UHD-HDVS-300-C-KIT.

The AT-UHD-HDVS-300-KIT can also be used with a variety of third-party USB cameras and speakerphones, and supports a maximum USB data rate of 120 Mbps. Below is a list of camera and speakerphone models tested and verified by Atlona. This listing will be continually updated as more brands and models are evaluated and validated.

Streamlined AV Systems for Meetings and Conferencing

Simple meetings demand simple systems. Attendees want to walk into a meeting space, open their laptop, and start a cloud-based conference.But to get quality results, systems are designed with AV Extenders, USB extenders, USB hubs, remote controls, cameras, microphones and all the associated cable runs. The HDVS-300-KIT was designed to eliminate the clutter and system complexity in huddle spaces and meeting rooms where USB cameras and microphones are incorporated into professional AV systems with just two devices and a single category cable. This kit also excels in hybrid rooms where a traditional HDVS system is required for in-person meetings as well as video conferencing.

Surface mounting brackets are provided with the HDVS-300-KIT for easy installation of the transmitter below a conference table.

Atlona PTZ Camera for HDVS-300 System

The AT-HDVS-CAM is a PTZ camera recommended for use with the HDVS-300-KIT. It can be purchased for an existing HDVS-300-KIT installation, or in an HDVS-300 system package as the AT-UHD-HDVS-300-C-KIT. A single SKU, for a soft codec conferencing system with PTZ camera makes it simple and convenient to specify for meeting or instructional spaces throughout a facility, building, or campus. At the same time, system designers bypass the time and effort in selecting and purchasing third-party conferencing cameras.

Automatic Display Control

The HDVS-300-KIT provides control to a display through TCP/IP, RS-232 pass-through, or CEC*, without the need for a separate control system. This simplifies system design and integration while reducing costs. With automatic display control, the HDVS-300-KIT can trigger a display to power on automatically whenever a laptop or other device is connected. At the end of the presentation, when the presenter disconnects the laptop, the HDVS-300-KIT forces the display to power off. Ease of presenter interaction with the system, and the savings incurred by automatic display shutdown provide a significant return on investment. The HDVS-300-KIT display control capability can also be triggered by an external control system.

A power button on the front panel can be used for manual on/off control of either the HDVS-300-KIT or the display. Front panel volume controls are also available to control the display’s internal audio, or another device with volume control, such as a DSP or another switcher.

* Consumer Electronics Control (CEC):Atlona does not guarantee the function of CEC with all televisions. We can confirm proper operation with many current Samsung, Panasonic, Sony, and LG TVs. Many manufacturers do not support the CEC “off” command when sent from a source and older TVs use proprietary commands. Atlona only supports those TVs that follow CEC command structure from HDMI 1.2a and support the “off” command when issued by a source. We encourage any dealer to get evaluation product from Atlona prior to designing a system around this control technology or be prepared to use other methods to control their displays if Atlona CEC is not compatible with the installed displays.

Reliable Auto-Switching

The HDVS-300-KIT automatically selects an input source based on detection of the 5 volt hot plug detect (HPD) signal, as well as active video. This ensures reliable auto-switching operation for all video sources, including DVRs, DisplayPort / Mini DisplayPort adapters, and other devices that always maintain the HPD line at the 5 volt “high” state but may not be delivering active video.


  • Teleconferencing with soft codecs – The switching transmitter is situated at a conference table for presenters to connect their laptops and integrate a USB mic or speakerphone, while the receiver is connected to the display and a USB camera.
    (See this featured application as an example, and read about the HDVS-300-KIT in this case study.)
  • Touch and interactive displays – The HDVS-300-KIT is also ideal for extending USB connectivity from a touch display to a PC at the transmitter location.
    (See this featured application as an example.)

Configured and Managed by AMS

The Atlona Management System (AMS) is a powerful network software platform ideal for configuring, managing, and monitoring the HDVS-300-KIT and other Atlona IP-controllable devices over a LAN, WAN, or VPN. AMS is available free from Atlona, and greatly streamlines installation and maintenance of several Atlona products throughout a facility or enterprise, from a standard web browser.
