This can be achieved if the camera has duel stream feature & NVR software supports transcoding feature assuming you have sufficient storage & bandwidth resources.

 

Transcoding can be applied to live video. Example: Taking single stream from camera, process it for Live view at VGA & 512 kbps, where as record it at original high video quality settings lets say 2 mp 5000 kbps.

 

Similarly if the camera can give 2 streams, you can use one stream to record at original settings (ex: 2 mp at 5000 kbps) for local view & you can use the 2nd stream to record at lower settings ( lets say 640x480 at 512 kbps) for remote view.

 

Please note that Transcoding is always a CPU intensive task as it involves double processing( encoding + decoding). You need better hardware to avail this feature.

A number of different NVR software packages can downsample for remote viewing, even on single stream cameras.

 

Milestone allows for setting different viewing qualities in their remote client, Avigilon can do it dynamically, and rescale it as you zoom in on an image (a pretty nice feature, and the overall package is good, as well.)

 

Exacq can do it in the web client, and it works on a number of different platforms (no browser plugins), but the standard client leaves a lot to be desired for playback features and functionality, especially with Megapixel cameras (in playback, clips have to download before you can view them).

Install DU meter on your desktop and see what happens. You might be worrying about nothing.

 

In some cases your screen resolution and and window size dictates the stream size.

 

I know it does on Avigilon.
