HELO Plus is a compact, advanced H.264 streaming and recording stand-alone appliance. HELO Plus offers both SDI and HDMI I/O with the capability to stream up to 1080p60 to a Content Delivery Network and record simultaneously. Two separate streaming destinations can be set up and recordings can be made to a combination of SD card, USB storage and NFS or CIFS network storage. HELO Plus also provides Picture-In-Picture and graphics functionality in hardware for compelling presentations made simple.

HELO Plus offers high quality streaming with ultra-reliable performance for any critical streaming service needs, including eSports, news, sports, education, creator, live events, and beyond.


HELO Plus is compact, with a very small desktop footprint.  It offers stand-alone capabilities with stream and record buttons on the front of the unit as well as LED indicators. Audio level meters provide valuable feedback about incoming audio. HELO Plus is fanless and silent, allowing it to be used almost anywhere without fear of introducing noise. SD card and USB ports are also situated on the front of the unit for easy access.

Remote or Local Control

HELO Plus can be easily configured remotely on a standard web browser, via the Ethernet connection, and using a desktop or laptop computer. Every function of HELO Plus is accessible in the WebUI, with multiple HELO Plus devices being easily controllable via a tabbed browser window. Once set up to your requirements, HELO Plus can also be controlled via the stream and record buttons on the front of the device, with audio level LED meters providing feedback for monitoring, or the system can be controlled directly from the included web-based UI. There’s also the option for remote control via the system’s integrated REST API.

Front of the HELO Plus:

  • Record button
  • Main and Backup LED indicators
  • Stream button
  • Streaming LED indicators
  • LED Stereo VU meters
  • 1x USB 3.2 Gen1 port (5Gb/s) for media recording and playback. This USB connection can supply 1A of current to the storage device, allowing it to work with modern, larger memory sticks.
  • USB LED indicator
  • 1x SD card slot for media recording and playback
  • SD card LED indicator

Rear of the HELO Plus:

  • 1x Stereo analog audio input
  • 1x Stereo analog audio output
  • 1x 3G-SDI input
  • SDI signal LED indicator
  • 1x 3G-SDI output
  • 1x HDMI 1.4a input

HELO Plus offers all the professional digital I/O you need to make HELO Plus the heart of your streaming service. The easy to access front panel buttons make starting and stopping your stream simple.




The simplified signal flow for video within HELO Plus neatly highlights the flexibility of the device. Tracing a simple pathway for each video input illustrates the encoder, graphics and recording options.


In this use case, a sports channel 1080p59.94 video feed is being commentated on in the studio, with the video output and embedded audio being passed directly to the SDI input of the HELO Plus. The HELO Plus streaming content is monitored using an HDMI monitor and headphones.

The first encoder is set to encode the video and audio as an RTMP stream, while the second encoder is set to output an HLS stream instead. HELO Plus allows high quality sports feeds with higher frame rates of 59.94 and 60 to be encoded easily, with greater detail and motion than lower frame rate content offering an enhanced user experience.



In this use case, the live event PGM feed is passed to the SDI input of the HELO Plus. The HELO Plus streaming content is monitored using an HDMI monitor and headphones. The first encoder is set to output an RTMPS stream, while the second encoder is recording directly to an SD card as a backup for later editorial use.


In this use case, the switched video output of a studio production is being recorded as a ProRes master on an AJA Ki Pro Ultra 12G. The Ki Pro Ultra 12G passes the video and audio via SDI to a HELO Plus. The HELO Plus is configured for a layout that shows the production video scaled down with a composite background provided by the frame store.

The Ki Pro Ultra 12G and HELO Plus are connected to the same Ethernet network, configured to be a group, with Ki Pro Ultra 12G as the leader. Hitting record on the Ki Pro Ultra 12G triggers the HELO Plus to start streaming and recording to USB simultaneously.

Grouping HELO Plus with other AJA video devices offers even more sophisticated control, with simultaneous synchronization for recording and streaming across multiple devices.



In this use case, a college lecture is taking place. The HELO Plus receives video over SDI of the lecturer. At the same time, the presentation on the lecturer’s laptop is being output via HDMI to the HDMI in of the HELO Plus.

The HELO Plus streaming content is monitored using an HDMI monitor and headphones. The HELO Plus has been set up to create a layout for picture-in-picture. In this case, the lecturer's video is scaled down and moved to the lower right corner as an overlay of the presentation.

This picture in picture combined output is passed to both encoders, with the first encoder offering a stream for students outside the facility via RTMP. At the same time, the second encoder utilises HLS for delivery to a college breakout area.


In this use case, an eSports video with embedded audio feed is distributed via an AJA KUMO 3232 SDI router to four commentary studios. Each commentary studio embeds its respective mixed audio track for each region. Each commentary studio passes out the SDI video and newly embedded commentary audio mix to a HELO Plus, four in total, with each connected to the others via an Ethernet switch.

The four HELO Plus devices are configured as a group, with HELO Plus #1 set to be the leader. Pressing record or stream on HELO Plus #1 triggers all the HELO Plus devices to stream to two alternate formats, 1080p29.97 and 720p29.97, keeping start and stop streaming for the group in sync across the various streams.

Group functionality across multiple HELO Plus devices is easily achieved on standard infrastructure, meaning the devices do not have to be physically near each other to function as though they were connected side-by-side.
