Take a look into the HELO Plus and its exciting features in this informative video.

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.

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.

Video Formats

• (HD) 1080p 23.98, 24, 25, 29.97, 30, 50, 59.94, 60
• (HD) 1080i 50, 59.94, 60
• (HD) 720p 50, 59.94, 60
• (SD) 525i, 625i

Video Codec Support

• H.264/MPEG-4 Encoder

Audio Encoding Parameters

• 32 kbps to 256 kbps 
• 48 kHz 2-channel stereo
• MPEG-4 AAC-LC

HELO Plus has the capability to stream and record up to 1080p60 simultaneously in the following combinations:

• Stream to two destinations and record to SD local storage simultaneously

• Stream to two destinations and record to USB local storage simultaneously

• Stream to two destinations and record to NFS/CIFS network storage simultaneously

Having a recorded backup of the video stream provides a high quality H.264 version for editing applications, with the most suitable storage being selected. Network storage may make more sense for edit sharing, while an SD card or USB recording provides an easy takeaway for clients or editors.

HELO Plus opens up a world of new streaming workflows for AV, live events, houses of worship, webcasting, corporate communications, production, and post. HELO Plus offers a scheduler that triggers pre-planned start and stop recording and streaming media, simplifying projects requiring definitive schedules.

The schedule may be programmed locally through HELO Plus' web UI, importing .ics files, or linking to external calendar providers such as Google Calendar. 

HELO Plus has dual encoders for streaming outputs, giving the flexibility to create different output settings from a single input source. The two encoders can have different packaging settings and different output frame sizes, which means that a single content stream can be presented in two ways to serve a wider audience.

It can also be duplicated across both encoders for added resilience. Either of these encoder outputs can serve as the source for the HELO Plus recording system as well.

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, 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 utilizes HLS for delivery to a college breakout area.

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, 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.
