I'd like to improve the time it takes to stream/buffer recorded clips out to the web-based commander. Sometimes it takes 30 seconds or more just for a 20 recording to load and play. (Using the paid-version of the web commander). And the video always starts playing too soon so I have to stop it and wait for it to finish buffering before I can play it without skipping.
Bandwidth @ home where the cameras are tests at 17 Mbps Down, 0.94 Mbps Up.
Bandwidth @ remote viewing location is 12.5 Down, 2.4 Up.
All the machines are gigabit to the LAN, no wireless.
There is nothing else competing for upstream bandwidth @ home. The PC commander is left running on a PC @ home so that clips are transfered to the PC as they're recorded. This is to prevent the SD cards from filling up and overwriting old video before it has been transfered to the PC. Closing commander on the home PC does not notibly increase performance of the web-commander.
The only clips that load quickly (around 5 seconds for a 20 second clip) are the ones I have previously watched. It seems like the Camera needs time to recompress the video file on the SD card in order to to stream it to the web-commander. If the file has already been compressed it plays immediately... Or maybe the clip has been cached somewhere and is loading more quickly for that reason.
Has anyone tried putting a high-speed (Class 10) micoSDHC card in the camera?
Any ideas/suggestions? Thanks!

Do you always stream video to the PC or is the PC Commander minimized in the system tray? I've found that when the cameras are streaming to the monitoring window it puts an extra load on the camera vs being minimized in the tray.
