In reply to a post by MrSaffron:

To get the CCTV from your mother in laws it will utilise the upload of that service.

have you confirmed what that upload speed is? If its an ADSL2+ service then THAT is the bottle neck plain and simple.

You would expect video from a webcam to operate usually in the 300 to 500 Kbps region, but varies based on what you have configured in each webcam.

Do not understand why?
OP has been using the BT upload without any problems for 2 years. Unless there is a problem with the BT line, why should there be a problem now?
There does appear to be a problem somewhere related to BT.
Can Op post exchange or, have I not read previously.

Well we know the upload which is 800 Kbps and fairly reasonable for ADSL2+ and not likely to have been faster.

Watching six video streams would be difficult with that bit rate, unless bit rate was very low.

Okay 800 Kbps reasonable to stream one IP video stream (note CCTV will stream at similar bit rates to a webcam)

6 at once would be possible, but only if the CCTV system was able to limit each stream to 100 Kbps, which is possible but with no details of the actual system in use and how it is setup hard to say.

This may just be a configuration issue and changes to how the CCTV system handles its streams, i.e. do you access each feed directly from the camera as an IP stream, or is it a web site on the wider internet?

If speed tests show you are able to get around 700 to 750 Kbps (0.7 Mbps) on the upstream, no sign that the connection itself is the problem.

Really appreciate you Guys, Thank you V much for your help.

The cctv cams are Swann 960HD Camera x 6. Display output default is 4:3, 1024x768, Fps 30. We access the cctv images by Swannview Link software which brings up an onscreen panel with a UID, User name and password which I guess is a direct link into the DVR so I would also guess it�s not exactly a website based thing.
I know that we can make changes to the DVR Settings (and maybe the Cams too?), but have not done so. (not sure if we can do it remotely either).

But it worked OK until (coincidentally?) Sky took over.

Could be hysterical parental controls blocking webcam uploads.

Irrespective of the Sky change, with just 800 Kbps then 1024x768 video at 30 FPS was not going to support 6 cameras streaming at once, unless quality was very low.

The Sky connection at 5 Mbps should be well capable of handling the 800 Kbps which is the maximum the DVR can upload from the other connection.

To watch a live video feed at a reasonable quality I'd expect around 300 Kbps for each.

The manual at http://www.swann.com/us/support-home suggests you should look at what settings are configured on the DVR for the substream (which is what is served over the Internet) Page 36

Hi MrSaffron, thanks for reply,
Sorry it�s taken a while to respond but I�ve been looking for the Manual that you refer to.
I can find only a PDF named, �NVR4-7200 No Resource issue�. That�s not our DVR but I will have later, the correct manual for our DVR in question. (Pro Series 960H H.264 DVR)
Your comment about low quality is true. Via the internet the footage is/was poor. But not that bad we couldn�t see what was happening and more importantly it�s not poor on the DVR which provides the evidence that the Police require. By viewing over the Internet, we can identify (albeit poor quality) footage that we can get the DVR (good quality) to backup and save.
But we can see only 1 cctv camera now. Not 6 as we could before.
C.

Could be, but unlikely if one is working.

Is the single video you can see at higher quality than previously?

Cannot recall if you've tried watching all the streams on another connection (i.e. not a Sky one) of similar speed to see if they work.

Re:batboy, there are no parental controls in place.
@ MrSaffron, No, in fact I would say it is worse. It occasionally loses the image completely for a few seconds.
From yesterdays post at 19:28 hrs �Further info:
I went next door with an IPad and connected wirelessly, he's on same Sky BB package as me via BT phone line. Result was same as me, only 1 of the 6 cctv cams displayed.
I then went other side next door neighbour with the IPad, he's on Virgin Media (cable?). There we had 2 cctv cams displayed.
Is it beginning to look like the prob is at the cctv end . . ? maybe as you suggest, BT possibly restricting the upload?
Regards Carl

Edit: But all the cams are working fine when wife connects IPad to DVR via Wireless lan when she visits her mum
