The update also adds support for MP4 and MOV file segments up to 360 minutes,  a new web UI video preview window,  support for exceptions to recurring scheduler events and an improved encode quality for low GOP size encodes,  many other feature enhancements.

Firmware Update is Free Available October 2017

HELO is AJA’s new H.264 streaming and recording stand-alone appliance. HELO brings both SDI and HDMI I/O into a single appliance with the ability to simultaneously stream out to your Content Delivery Network (CDN) as well as encode and record beautiful H.264 files to either SD cards, USB storage or network based storage simultaneously.

Portable and Packed to go

HELO’s small and robust form factor is essential for your busy schedule. Live events, webcasts, production and post locations vary and you need a device that can take the heat. HELO is designed to travel well, fit wherever needed and continuously deliver; all with full size connectivity.

HELO offers both HD-SDI and HDMI source inputs in a single device with the ability to encode up to 1080p 60 in beautiful and efficient H.264.

Stream out to your Content Delivery Network (CDN) and record to SD cards, USB storage or network based shares simultaneously.


Your goal is efficiency with beautiful results.

HELO encodes to H.264/MPEG-4 ensuring bandwidth efficiencies with widely compatible files. From tablets to Smartphones, Desktops to Smart TVs, no translation necessary.

2-Channel Stereo Audio can be encoded at up to 24-bit 48kHz at data rates ranging from 32kbps to 256kps in Mpeg-4-LC, allowing you to make the most appropriate choice for your project's needs.


Streaming can be complex. HELO makes it simple.

A USB connection and robust web-browser based UI allows you to setup and configure your CDN connection before you even arrive at your event. Once there, simply press the Stream button and deliver your project across HELO’s Ethernet connection, which allows support for RTP/RTSP, RTMP as well as Unicast.


Live means Now. Live means Pressure.

HELO offers a dedicated Record button right on the front of HELO’s small and mobile interface for immediate recording. Simply plug in your NTFS 3.1 or FAT 32 formatted USB drive, SD card or connected network storage and record immediately.

Conveniently Connected

Mass Media

Cost effective media choices.

HELO’s H.264 based encoding not only ensures beautiful, efficiently sized files, it means your recording medium choices are wide open. Utilize USB thumb sticks, drives and RAIDs, common SD or SDHC media or network shares across a switch. Pick to suit your project.


Webserver Built In

You serve the Web. HELO serves You.

AJA eMini-Setup and HELO’s easy to use web- browser Interface make HELO simple to setup, configure and update firmware at any time. You can connect to HELO either via its direct USB port to set static/dynamic IP addresses though AJA eMini-Setup software or over the network using HELO’s web server generated UI.

Expand your Choices

For Ki Pro or CION Users, HELO expands your HD pipeline with up to 1080p 60 support. Simply connect via 3G-SDI or HDMI and record H.264 proxy files for fast onsite portable editing on a laptop and stream your live capture or playback as needed.
