Hi,
I just test D-ViewCAM, but it seems not working as a service. You need to open an (auto-)load the program to record the video. In addition, it create video in .dat format, didn't find a way to create a mpeg or avi format.
I'm surprise that D-link don't really need a simple solution to record the cam feeds.
ffserver seems better, not yet tested.
Regards,
Laurent
