Screen ONVIF Tested

By Ethan Ace, Published Oct 23, 2015, 12:00am EDT

IPVM ImageRecording a PC's screen to a VMS has several uses, but historically has required expensive dedicated encoders or specialized software for each VMS.

Now, a new offering called Screen ONVIF [link no longer available] has released a standalone application which streams a PC's desktop via ONVIF, claiming compatibility with any ONVIF NVR or VMS.

We tested out Screen ONVIF with several VMSes and NVRs to see how it performs and test compatibility with leading VMSes and recorders.

"There is a separate version under development (available on request) which allows editing of some settings (port, credentials, etc.) via an XML file, but there is no configuration dialog or wizard, etc."

Interesting. I'm willing to bet it is like barebones development, get the product out the door and see how well it sells and we'll improve it if it does.

I know some VMSes like DVTel and DW Spectrum support recording the monitor the client is installed on. Have you had a chance to test those and compare to how well they work with something like this?

We have not tested any other screen recorders. The main reason we tested this one was that it is designed to work broadly with many systems. Proprietary screen recorders may be awesome but even if they are, it only is applicable to their limited customer base.

I understand. I was also thinking something like this program would be useful as an easy way to "import" precorded video files like MP4 or AVI into a VMS for show purposes, by simply playing them on the screen and recording it like a camera into the VMS, but the 720P limitation basically "limits" that option. I've tried streaming the files out as RTSP with VideoLan's VLC Player but could never get it to work.

If the surveillance industry were junior high school, ONVIF would be the kid everyone is always giving wedgies to :(

Not only do they have hundreds of cheap Chinese surveillance manufacturers co-opting their name/branding, now this bully comes along and just snatches up their name and uses it to name their flagship product.

Not technically an ONVIF stream, but VLC allows you to stream your desktop via RTSP.

Und 3, have you been able to get it to work? I never have.

No, I actually haven't done it. I know it's supposed to be possible.

I have used VLC's screen capture (to a file) successfully.

And I have taken a wireless GoPro stream and and restreamed it to a VMS via RTSP successfully, so this didn't seem any harder than that.

Did you get it to work at all?

Hi Und1 and Und3.

I did manage in the past to stream any Onvif camera via VLC.

I don't recall exactly the step I followed, just that VLC was a little bit troublesome to configure.

Anyway, I have the parameter commands saved here. If you give it a try, it might work

"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" rtsp://User:Password@192.168.1.201/h264 --sout=#transcode{vcodec=DIV3,vb=800,acodec=mp3,ab=128,channels=2,samplerate=44100}:std{access=mmsh,mux=asfh,dst=0.0.0.0:8888} --sout-keep

Thanks, Ric. Will have to file away and try next chance I get.

Hey Ricardo!

Here though we are talking about streaming ones desktop as if it's a camera.

Is that what you are referring to?

Ops sorry Und3 and Und1.

I was too hasty in my answer. The parameters I provided would be to transmit via VLC a rtsp input stream, hence the ip 192.168.1.201.

This would require you to already have a software streaming your desktop via rtsp, which is the purpose of the software in this topic. In here VLC would just be a streaming server, using your pc so it could allow more connections.

Sweet product! any one know if there are HDMI Onvif Encoders out there?

Antrica has some.

I know of an HDMI monitor, which has a network connection, and streams ONVIF out. So it is an HDMI encoder with a bonus monitor.

Hi IPVM,

Pre-dominantly , the compression used by proprietary screen recorder (Milestone) or Mentor in DVTEL are in MJPEG format and are limited to some limit of FPS. This might be due to the fact that they are ensuring the the captured screen do not go through too much compression before delivering to the VMS which in turns equate to higher hidden CPU on the source end.

Do you have any report on the amount of CPU usage used while the ONVIF screen "streamer" is compressing video and sending via RTSP

The above information will be helpful

Thanks

1080p60 Encoder is definitely expensive for video surveillance market but I believe it's worthy if you think about niche market such as medical, broadcasting etc.

Also I believe many units were installed with current VMSes as well due to Onvif. This is the key factor where this encoders were sold at that expense because there were not many 1080p60 Encoder/Decoder supported Onvif.

There are many input formats to feed and many protocols are supported on HW Encoder such as RTSP, RTP, MPEG-TS, RTMP.

If they make simple HDMI encoder, the price will go down a lot.
