Overview
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.
Hardware
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.

Simultaneous Stream and Record
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.
Layouts - Powerful Multi-Input Video Processing
HELO Plus brings the exciting layouts feature, allowing multiple inputs to be combined into a single screen with a graphic element overlay. A layout enables the user to combine the SDI input and the HDMI input into a single output stream and then add a graphic (video + key) into that composite. The layout can have up to 3 layers, and their priority can be arbitrarily adjusted to suit the customer’s needs.
In addition to the layering engine, both the SDI and the HDMI layers can be arbitrarily downscaled and positioned anywhere in the frame. Effectively, each live video source can be used in its picture-in-picture (PiP) element.
The system also has an internal matte generator, which can be used as the background. In this way, the graphic can be keyed over the dual PiP images, which are “over” a flat matte background.
The system can accurately switch from one layout to another frame, allowing the user to “cut” between layouts during a streaming session. Layouts are stored in one of the 20 Presets, allowing users to recall all of the parameters needed for a specific purpose. There are 10 layouts stored in each preset, so the user recalls the show’s preset and can then switch between those 10 layouts at will.
The graphics system is equally impressive - The system stores 90+ images in its internal, non-volatile memory.
