I didn't receive a reply from tech support yet..
When my DCS-2330L camera is functioning properly, I can get access to the images/video from mydlink.com
But if I disconnect my camera from power, I see:
"Your DCS-2330L is offline."
on mydlink.com
So, I'd say they don't save anything (images/video) to their cloud.
The "cloud" they talk about appears to be a live internet connection to camera, and/or to the contents of the microSD card inside the camera.
If the connectivity is gone, so is the ability to get at *any* of those images/video.
I may have to rethink my security strategy regarding the use of this camera.
I could try to use the D-ViewCam app and record the stream to a local hard disk or something...
Or write a script to download the files from the SD card to a local hard disk periodically.
But I'll have to do that at a backup rate faster than a burglar could steal my camera :-)
