In my home Lan i have a DNS-327L, 2 DSC932L and 1 DSC930L.
Whenever My Surveillance is enabled in Share Center Home My Folder screen all 3 cams start streaming and the bandwidth consumed is aprox 600KBytes/s.
This happens even if My Surveillance app is closed (although active), and with no recordings active.
I think that the correct behavior should be that video streaming would only take place when My Surveillance app is opened or cam recording active. This will avoid useless bandwidth consumption.
The only way i found to stop this behavior is to disable My Surveillance.
Any help appreciated.
