Bandwidth

When using Witness with the cloud enabled and a user connected via a cloud account remotely to site the remote viewer is struggling with a live feed due to the sites witness is installed in's limited internet connection 12mb up, 1mb down max.

On hardware NVRs there is normally an option to lower the resolution of the remote viewer, reducing the bandwidth used.

So my question, is it possible to limit the bandwidth used by remote cloud users, ie the cloud user uses the lower sub-stream feeds as not to impact on the local network users high quality feed?

 

Thanks

  Hi Martyn,

  You can specify the quality while viewing the the stream through Cloud (upper-left corner). There is a possibility to select Low quality which will save you bandwidth

  Hi Boris, Thanks for your reply but you have miss understood my question, or i did not explain it very well.

  The problem is not the bandwidth on the remote viewing device. The problem is the amount of bandwidth the NX server is using to upload the streams. the site only has 2mb up and 12mb down.

  So i am looking to reduce the stream size from the server for cloud users, not for local LAN users. 

  In a perfect world LAN users (local) would user primary stream, Wan users (cloud) would use secondary lower res stream.

  Have i explained that any better ?

  Thanks

  Martyn

  Hi Martyn,

  Boris is correct. When you view a stream through the NxCloud it will by default use the best possible stream, but when the bandwidth is not sufficient it will automatically switch to the secondary stream. 

  In case you want to force the use of the secondary stream, you can click on the gears in top-right of the viewing pane and select 'Low' and in that case, the Nx Cloud will show the secondary stream and thus reducing the bandwidth consumption.

  Hi Norman, 

  Ok so selecting "Low" is forcing the secondary feed. Thats good to know.

  My question is not about the bandwidth on the "viewing" device, thats fine. The problem is at the server side, The bandwidth the server has is low. Maybe i am miss understanding.

  My understanding is the "server" is updating "the cloud" with both a primary and secondary stream all the time, regardless if a user is viewing the feed from the cloud or not. Is this correct?

  If thats correct then the bandwidth the "server" is using to update "the cloud" is too high for this slow connection.

  Is it possible to force the "server" to only send the lower res secondary feed to "the cloud" and therefore force all "cloud viewer users" to only use the lower res secondary feed i.e no primary feed?

  The primary high res need to only be available on the local LAN for on site viewer.

  Sorry to be a pain, 

  Thanks

  Martyn

  Hi Martyn,

  Regarding: 

  My understanding is the "server" is updating "the cloud" with both a primary and secondary stream all the time, regardless if a user is viewing the feed from the cloud or not. Is this correct?

  Nx: That statement is incorrect. The connection only exists when the camera is viewed and only the stream that is displayed. 

  Is it possible to force the "server" to only send the lower res secondary feed to "the cloud" and therefore force all "cloud viewer users" to only use the lower res secondary feed i.e no primary feed?

  Nx: Only in the way, I described in my previous comment. 

  Sorry to be a pain, 

  Nx: No worries. More than happy to assist if possible.
