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.

SRT Support

SRT is an open source video transport protocol and technology stack, developed and pioneered by Haivision, that optimizes streaming performance across unpredictable networks with secure streams and easy firewall traversal, bringing the best quality live video over the worst networks. The SRT Open Source Project, supported by the SRT Alliance, is a collaborative community of industry leaders and developers striving to achieve lower latency internet video transport by continuously improving open-source SRT.

HELO Plus includes SRT (plus encryption) to ensure you are well positioned to deliver streaming video content securely, with low latency and secure reliability.

HELO Plus Connections and Indicators

Operational Flexibility

HELO Plus’ small footprint form factor and silent operation allow it to fit on any desktop, with the operator using the easy to access front panel start/stop buttons. But just as simply, HELO Plus can be operated remotely from a desktop or laptop computer via Ethernet, which is especially useful for multiple HELO Plus use cases. HELO Plus is designed to give you the flexibility to configure and deploy HELO Plus to your needs in the field, home, or studio. HELO Plus fits any streaming need imaginable, from sports, news, creator, education, eSports, remote workflows, and many more. REST API capabilities provide control for all functions of the HELO Plus, regardless of the scenario, allowing for user developed integration and automation.

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.

Calendar Integration

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.

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.

Dual Streaming Outputs

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.
