Polycom HDX vs RealPresence Group Series

Launched at the start of 2008, the Polycom HDX Series was rolled out to provide organisations with a much improved HD Video Conferencing experience, which included breakthrough advances in the technology such as Lost Packet Recovery, making waves across the Video Conferencing market. Many users were thrilled with the new offering, with a high quality interface and simplistic collaboration that Polycom believed helped them offer the deepest and broadest portfolio of advanced video collaboration solutions available on the market at that time. The Polycom HDX Series has been made end-of-life as of August 2016.

In 2012, Polycom introduced the new RealPresence Group Series systems, with the aim of improving the experience even further – higher quality video & data resolution, the addition of features such as Polycom VisualBoard and SmartPairing technology, and better integration with other non-standards compliant systems & solutions, such as Microsoft Lync & SVC.

With the recent announcement of the Polycom HDX series being made end of life, it’s no longer a matter of if you should choose the Group Series, but when. So what’s the difference (and similarities) between the two?


The HDX & Group: So how do they compare?

Both the HDX and Group systems provide professional quality video, audio and data conferencing, with features including People + content, Lost Packet Recovery, and H.264 high profile support, with innovative technology that provides a UltimateHD quality resolution at 50% less bandwidth. Both solutions are also Microsoft Lync compatible and qualified, although this does require added licenses or infrastructure, depending upon the required integration.

Let’s take a look at differences between two sets of comparable room based systems;  The HDX 7000 vs the Group 500, and the HDX 8000 vs the Group 700.

In summary, the Polycom HDX Series has been a great solution for many customers, and still provides some features including ISDN/POTS that are key to organisations in government, judicial and public sector organisations. However, with a much improved look and feel, a more simple to use experience that is consistent across the whole Polycom portfolio, and better integration with solutions such as the Polycom Producer and Microsoft Lync/Skype for Business, the Polycom RealPresence Group Series provides the next step for organisations looking to greatly improve video conferencing and collaboration across their organisation.

    Thanks for the good insight into the Polycom HDX Series vs Polycom RealPresence Group Series. Really interesting comparison with some very important information. I am a Polycom employee and help businesses look at the benefits of both of these solutions – Good to see a Polycom partner sharing useful camparison information to help customers and organisations decide what is really right for them.

    People should take a further look at the Polycom SmartPairing and NoiseBlock technology features which are really great innovations added to the newer systems. They are so beneficial to many customers.
