HDMI to USB Live Streaming

HDMI to USB Live Streaming

This is one of the HDMI to USB live streaming setups that we use at CCTV Camera Pros. This system uses on of our multi-camera live TV display systems that includes an HD CCTV multiplexer and up to 4 HD security cameras. The wireless remote control that us included with the VM-HD4 multiplexer allows broadcasters to switch between single and multiple camera views in real time while streaming.

You can see that we are using the HDMI loop output of our HDMI to USB converter to display our cameras on the TV in addition to capturing the video via USB-C on our Macbook Pro.

YouTube Live Video Stream

Here is an archive of an actual YouTube Live video stream that uses the HDMI-U3, four HD security cameras, and a VM-HD4 CCTV multiplexer. *Please note that you may need to click the image twice for the video to begin playing.

HDMI to USB Video Capture Setup (multiple cameras)

HDMI to USB Video Capture

This is how the HDMI to USB video capture is setup. We are using a multiple camera system for this example. You can also refer to the single camera streaming diagram below.

  1. Starting on the right, there are 4 HD security cameras connected to a CCTV multiplexer.
  2. These cameras are hard wired using pre-made security camera cable.
  3. The 4ch multiplexer includes a wireless remote control. The person that is streaming video can switch the video display between single and multiple camera views using this remote.
  4. The HDMI video output of the multiplexer is connected to the HDMI input on the HDMI to USB capture box (HDMI-U3).
  5. Optionally, the HDMI loop output on the HDMI-U3 can be connected to a TV monitor, so that a local live monitor display can be used at the same time the computer is capturing video.
  6. The USB 3.0 port on the HDMI-U3 connects to the HDMI input on the PC. Please note that if you are using a Macbook, you need to purchase the optional USB-3 to USB-C (Thunderbolt) converter.
  7. The PC, a Macbook Pro in this case is running Open Broadcaster Software (OBS). OBS is integrated with Facebook Live, YouTube Live, Twitch TV, and many other live streaming platforms. If you plan on streaming a Zoom meeting, then you can install the Zoom broadcasting software on your PC. The HDMI-U3 has been tested and works very well with OBS and Zoom.
  8. The Macbook is connected to a network router to provide an Internet connection.
  9. The Internet connection enabled the video capture to be sent to the streaming platforms.
  10. You can also connect a USB microphone to the laptop for audio streaming. The HDMI-U3 capture device also supports HDMI audio, however we recommend using a separate USB microphone.

HDMI to USB Video Stream via DVR (multiple cameras)

HDMI to USB Video Capture

Another way to video stream multiple cameras is by using a security camera DVR (instead of a video multiplexer). The setup is the same as the one described above, except the DVR is used in place of the CCTV multiplexer. One of the advantages of this setup is that businesses can use their DVR for security and also for live streaming video.

HDMI to USB Video Capture Setup (single BNC security camera)

HDMI to USB 3 Adapter

The single camera live stream setup works the same way as the multiple camera setup that is described above. The difference is that an HDCV-3-T BNC to HDMI converter is used instead of the video multiplexer. The HDCV-3-T has a single BNC video input that is compatible with HD BNC security cameras (AHD, HD-TVI, and HD-CVI formats supported). Everything else works the same as with the multi-camera system.

Video Camera / Camcorder Streaming

Camcorder HDMI to USB

Video Game Streaming

HDMI to USB Video Game Streaming

The HDMI-U3 is used by video gamers players to live stream video game play to Twitch, YouTube, Facebook Gaming, and all other streaming platforms that gamers use.

Works with XBox, Playstation, Nintendo Switch, and any other game console that has HDMI output.

Video Game Streaming with Multiple Cameras

Video Game Streaming Setup

Here is another video game streaming setup. This one combines the video signal from the HDMI output of the game console with video from 3 security cameras. This is so that viewers can experience the video game play as well as the location where the play is taking place. Serious video gamers could stream a video game party with this setup. You can learn more about this one in our blog post: Multiple Camera Video Game Streaming Setup.

HDMI to USB-C Thunderbolt Adapter

HDMI to USB-C Adapter

5 of 5 Great CCTV products, manuals, and support! November 10, 2020
Reviewer: JasonG from Victoria, BC Canada  
CCTV camera pros are my go to guys for technical support and tools for HD-CCTV cameras. The DVRs, cameras, and multiplexers are high quality and very durable.
I have also found their online library of manuals and videos very useful for comparing equipment and troubleshooting.

5 of 5 Great Help and Support November 2, 2020
Reviewer: RickTfmNewLondon from New London, CT  
I had an application in mind but didn't know enough about how to accomplish what I wanted. So I saw an ad from CCTV Camera Pros and called them and spoke with Mike. I told him what I wanted to do and since it wasn't in his swim lane he listened and made a recommendation to try the HDMI-U3. Mike told me I could try it and if it didn't work, I could send it back for a full refund. I received the unit from CCTV, tried it, and unfortunately it didn't work for my application. So I sent it back and got a prompt refund. I was really impressed with CCTV Camera Pros!!

Reviewer: BenO from Hamilton, TX  
I run the video and audio in a small church. With the help of the sales expert who recommended there video capture card I solve my problem to be able to live stream. The card works with no lag and is able to bring both the video and audio into OBS from the video camera. Thanks for the technical help and recommending a very good product.
