How to record an Audio-Video conference on a USB flash drive

Video conferencing organizers can now record video conferences without costly and sophisticated solutions. Epiphan’s recorders series offers high-performance solutions that allow broadcasting and recording of video conference events. These products are an effective means of delivering different audio-video conference streams through the network and recording them on solid state memory or to a network storage device. This capability enables a meeting holder to record the conference in a high quality for those who could not attend.

How does video conferencing work with the Lecture Recorder x2™ recording appliance? Read on to know more on this subject. In our example the video conference organizers will stream a DVI/HDMI™ camera signal along with analog audio and record it on a USB flash drive.

USB into Lecture Recorder x2


  • Lecture Recorder x2
  • USB Flash Drive
  • Microphone
  • Laptops with network access for the meeting holder and all viewer participants
  • Camcorder with DVI/HDMI output
  • DVI cables, HDMI to DVI adapter (depending on the camcorder output connector)

Step 1: Connecting the Lecture Recorder x2 equipment

The first step is to setup Lecture Recorder x2 so that it is streaming a display sources to the internet. Using a simple computer display is a good way to test this setup.

  1. Hook up a camcorder to Lecture Recorder x2. If the camcorder has a DVI output, use a DVI-to-DVI cable. If the camcorder has an HDMI output, use an HDMI-to-DVI adapter.
  2. Hook up Lecture Recorder x2 to the Ethernet through its Ethernet RJ-45 port.
  3. Connect a microphone to the recorder’s Audio in port.
  4. If needed, turn on the camcorder.
  5. Attach a computer monitor to the Lecture Recorder x2’s output port to ensure the stream is being displayed on the monitor.
  6. If you know the URL/IP address of the broadcast, use it with your browser or media player to make sure the video/audio feed is streamed over the network. If you do not know the URL/IP address, perform this operation in the step 2.

Step 2: Lecture Recorder x2 Settings

If you do not know the URL IP address for your Lecture Recorder x2 installed above, download the Network Discovery Utility from the Lecture Recorder x2’s product page to the laptop you are using to configure the system.

  1. Install the Network Discovery Utility application on your laptop and start it up.
  2. Click the Search button.
  3. Your recorder will be found on the network. Its IP address will be also available. Provide the participants with this information.
  4. Click Web config to start the Web admin interface.
  5. Click on the Viewer Access section of the interface to set up the viewer’s access to the broadcast. Specify the viewer password.

Step 3: Conference Recording

Once the participants know the address of the streaming broadcast and the viewer broadcast’s credentials, they are able to watch and listen to the video conference. Lecture Recorder x2 copies the previously recorded files to the inserted USB flash drive starting from the oldest record to the newest. Flash drives are not capable of recording data on the fly. While the previously recorded data captured by the appliance on its internal solid state memory will be backed-up on the flash drive, the currently recording file cannot be copied until the file is closed and available for copying. To record the conference to a USB flash drive, do the following:

  1. Before the conference starts make necessary settings in the Archive section of Web interface. Set up time or size limits for the recorded files. When either of the limits is exceeded, the system starts recording data in another file.
  2. Stick a flash drive into a USB port on your Epiphan appliance and press lightly. The stick fits into the port only one way. After inserting, the appliance will recognize the stick. The flash drive’s LED (if any) will be blinking indicating data transfer.
  3. Once the data has been copied, safely remove the flash drive. To check its free storage, files that have been copies and their size, insert the drive into a computer and see its properties.
