ONVIF Profile G Video Storage Test

Author: Ethan Ace, Published on Aug 26, 2016

A standard to retrieve video stored on 3rd party devices. This is the aim of ONVIF Profile G.

The proprietary nature of accessing recorded video has been a problem for years, forcing most users to limit themselves to a single recording platform and holding back the use of edge storage.

Now, after 2 years of release, 1396 devices, across more than 30 manufacturers, officially support ONVIF Profile G.

But does it work?

We tested 16 cameras from 6 manufacturers (Axis, Dahua, Hikvision, Panasonic, Pelco and Samsung) to see how well it did.

The fact that Profile G widely worked is a minor miracle

Indeed it is. I had a privilege to witness Profile G evolving and would like to thank several really nice people behind it:

  • Steven Dillingham, chairman of Onvif Profile G work-group, former Bosch employee
  • Priyesh Fatnani, Canon, active member of Profile G work-group
  • Fredrik Svensson, Axis, active member of Profile G work-group
  • Hugo Brisson, Genetec, chairman of Onvif Test Tool work-group
  • Hirokazu Kitaoka, Panasonic, active member of Profile G work-group
  • + all other people from dozens of companies who twice a year participate to Onvif Plugfests in seek of better interoperability.

Thanks for you hard-work guys, you made this possible!

Anzor,

Thanks for sharing that.

Do you have any sense of why VMS adoption is so lacking? Do you see it as being hard for VMSes technically to adopt or?

The imbalance between VMS and camera support is extreme.

As a technical guy I would like to answer only technical part:)

Do you see it as being hard for VMSes technically to adopt or?

Short answer: not really. But it depends on VMS software design.

ONVIF has extensive embedded storage support, with 3 dedicated services:

I would consider first two relatively simple two implement from VMS side and Recording Control I find challenging for the both sides (camera, VMS)

Profile G is really about first two. Recording control is mostly intentionally moved to conditional part of ProfileG because of it's complexity.

If we consider only mandatory features, Onvif replay streaming format has some extensions to standard RTSP protocol. This means that you have to hack your rtsp library to work properly and implement some things. And it is not as simple as receiving live stream from camera, for that you can use freely available standard libraries. But this work have to be done from camera side also, so it does not answer your primary question.

Most challenging part I see is to integrate this feature to legacy VMS design. And this task is really depend on internals of specific VMS.

Nevertheless we successfully implemented ProfileG client for Intellect and Next. This two products are very different inside.

Anzor, thanks, that's great.

Recording control is mostly intentionally moved to conditional part of ProfileG because of it's complexity.

If one does not implement recording control, what cannot be done?

Related, does Axxon implement the recording control?

Recording Control gives ability to manage space of device onboard media and ability to configure recording job.

Oversimplifying things, "managing space" means that if you have 16 channel NVR, you can create separate recording archive for each camera with different size.

With recording jobs - ONVIF gives ability to start or stop constant recording with specified fps, resolution, video codec. Limitations: only constant recording, there is no way to configure recording based on onboard motion detector events.

Related, does Axxon implement the recording control.

No, we don't have it currently. We are eager to implement recording jobs control - ability to start stop recording. In fact we have most of the work done for that, but lack of proper support from device side is the main problem for us.

Anzor, thanks! Very clear and informative.

Now, after 2 years of release, 1396 devices, across more than 30 manufacturers, officially support ONVIF Profile G.

Wow, 813 of them are Hikvision.

Considering the fact that Axis has implemented G in numerous cameras, as well as the fact that they are an active member in the G committee, not to mention the fact that they started and chair ONVIF itself, one would expect that their "top 5" VMS would implement G matter of factly.

Anyday now, probably...

I have been advised by Luxriot that the new Evo VMS does support profile G.

Thank you for the test, I have been eager to start testing this technology myself.

Cameron,

Thanks for the feedback.

Luxriot might have developed code for profile G but they are not allowed, by ONVIF rules, to claim they support until and unless they run and submit the conformance test. Luxirot has not.

There are only 2 VMSes (i.e., clients in ONVIF terminology) that ONVIF lists as supporting Profile G:

Moreover, Luxirot EVO has is NOT ONVIF conformant. You can verify this by searching under their corporate name (A&H Software) which only returns their old VMS from 2014.

If you use Luxriot, please encourage them to obtain official ONVIF conformance for both legal and performance reasons.

Hi John

Yes I have raised that matter with them and they tell me that since the product is so new they have not had it submitted to the conformant database yet, though it is coming.

Luxriot might have developed code for profile G but they are not allowed, by ONVIF rules, to claim they support until and unless they run and submit the conformance test. Luxirot has not.

What's Milestone's excuse?

Milestone hedge it by saying 'relevant parts of' so they can reasonably argue that they are not claiming to be fully conformant.

Of course, the bigger problem with the Milestone ONVIF Bridge is that it works poorly.

Milestone hedge it by saying 'relevant parts of' so they can reasonably argue that they are not claiming to be fully conformant.

Do you personally find it reasonable?

What about a camera without conformance claiming

"XYZ Camera is compliant with the relevant parts of Profile S"?

Where is Milestone's certificate of "relevant" conformance showing where it passed and where it failed?

Its deceptive: most people trusting in Milestone would get the impression that it was Profile G compliant, or at worst that Profile G itself was somehow flawed with irrelevant requirements.

I do not like it and do not think they should use that. Related, I think ONVIF should not allow it, not only because it could mislead but because the likelihood of 'relevant parts' actually working is much lower.

We develop onvif G cloud storage solution I am looking for list of cameras that support onvif G - at the moment we support hikvision dahua pannasonic but I would like to add more brands Dov Avnon the Netherlands

2400+ cameras from 25 manufacturers are currently listed as officially ONVIF G conformant (check their conformant directory).

Here is a CSV export of those 2,400+ ONVIF G cameras.

2400+ cameras from 25 manufacturers...

and curiously ~1200 from 1 manufacturer, Hik. Btw, did you notice Hik is in ONVIF vendor list twice now, with and without "Hangzhou"? Choose the old one for no results.

I had not but see it now. I forwarded this to ONVIF to let them know.
