Alternative methods of reducing Bandwidth Consumption would be to change the following settings of the IP Network Camera:
Frame Rate
Video Quality
Maximum Bit Rate
Resolution Size (Picture Size found under Video options of camera’s configuration pages)
Removing devices on the network to reduce Bandwidth consumption.
Also, under the “Network” link for the camera’s configuration page, there is an option to “Improve Audio in Low Bandwidth Environments”. You may wish to have this option selected.
