AJA HELO Reviews

Takes a Bit to Set Up but Excellent Once Working

The Blackmagic box for live streaming was plug and play...the AJA required more effort to figure out. Once that was accomplished we like what it produces especially streaming and recording.

Most complicated and unreliable streamer

By Maroun

We got this streamer a year ago and since then we are struggling with it, very complicated interface, you should have a high level of IT when it is supposed to be made for video people. We asked help from AJA, they replaced the unit and then we struggled another 6 months with it, several hours with AJA support, tens of emails, whatsapp group with technicians and chats, no chance to go online. Im selling it since it for whatever i can get. We got the BlackMagic web presenter and we are online in 5 minutes.

Does the job

Solid as a rock, does what it says it is going to do, great features. Took me a day to figure out that if you have for instance both the USB and SD configured to record, well you better have media in the slots, or neither will record. It's all or nothing. But once you understand these things, I really like the preview screen of the video in the browser, and the obvious indicators that streaming and recording are happening. Looking forward to using it more, and testing the remote control capabilities. Can't beat the price either.

Nice streaming device on a budget beware if using several

if you're using one (a single box) on a network subnet with V2.0 firmware, you're likely to have a nice time with it- however if you try to put more than one of these on the same network subnet be ready for chaos as they behave unpredictably with some sort of strange ganging function which can't be disabled and isn't wanted. I put each of them on their own /30 vlan an that helped a lot which may be above and beyond for many people to configure their networks like this. had to return them however because the unit feels overly fragile for portable applications and it cannot encode RTSP over TCP only supports UDP currently which is a non-starter for my environment. AJA support did not return calls or emails to assist or offer a long-term outlook when requested.

Rock solid, ready for the long haul.

I spoke with another user who is very deep in the streaming world, and he highly recommended this appliance. Easy to use, worked the first three times I tried it without a hitch. Excellent system, the newest firmware seems to have taken care of any instability.

Doesn't comply with Wowza server, support not helpful

Bought this to stream out live sport events. Outputting to Wowza caused issues that they've only seen happen with Helo. AJA support staff was not helpful.

We livestream the output of our Leightronix Ultranexus for our City cable TV channel, using this to send Live stream to DaCast . Was very easy to get going, had to change (lower) the Bit Rate per Dacast support, as initialy it was using up to much bandwidth. Works great. 24/7 live-streaming for 7 months now, Solid performer. 1280x720p 29.97fps H.264 @ 1.50Mbps, 120 GOP, MP, CABAC, 128K audio .

Great single stream device

This is solid and easy to setup. Great for producer to 1 button stream, no confusion. I wish it would stream multiple RMTP at once.

See any errors on this page? Let us know



Everything works great outside of the HDMI output. Turned it on in the settings but not seeing anything when plugged into a monitor. Any ideas?
Asked by: Nathaniel
Apparently there are HDMI timing issues that are making some monitors unable to display the HELO HDMI output.AJA has a 2.0 firmware coming out very soon. Please register your HELO on the AJA website and they will notify you as soon as the 2.0 firmware is released. &lt;a href= target= _blank &gt;;/a&gt;

Can i use Helo with Wirecast Pro?

We believe so. Please see here for Wirecast compatibility. We are not sure of this application because Wirecast already does what Helo can do. In order that we may better assist you, please write us with further detail. [email protected]

Is there a way to use some kind of bonding solution with this to maintain bandwidth or stream in areas that don't have reliable wired internet?
Asked by: Dennis
AJA does not offer a bonding solution for the AJA HELO H.264 Streamer &amp; Recorder. It would be optimal to speak to your IT department to prioritize bandwidth for your stream.

Does it do Closed Captioning?
Asked by: Bob J.
I emailed AJA's tech support on this one. From their response: Yes, the HELO will strip off the closed captioning. I ran your original question by the Product Management teamand will be sure to pass along the information . . .

Does this unit still have a 60 minute record limit (for a single clip) as it did when it was a new release?
Asked by: Richard
That is our understanding. It should not be an issue. It does not stop recording; it just starts a new file.

Do either of the outputs have an overlay functionality? Such as showing streaming status, record length, etc? Or are they mostly just pass throughs?
Asked by: Josh
unfortunately it cannot. it is just a pass through.

Does it support simulstream ....can it stream to custom rtmp server, facebook live &amp; youtube simultaneously?
Asked by: Arun S.
This product is able to stream and record at the same time. It is not able to send out a signal to two different CDNs. For that you would want to look at the Matrox Monarch HDX, B&amp;H # MAMONHDX. This is a Dual-Channel H.264 Video Encoder that can stream out to two different locations.
