I started a post in the DCS-930L forum comparing the difficulties of setting the frame rate, and the differing unresponsiveness of the two camera types; titled: "Not obeying frames per second settings"
Summarizing for this forum: The DCS-932L, when enabled for Motion Detection + ftp, sends a several second long sequence of images at 15 fps; I find that the fps controls just have no effect.
This really fills up the ftp storage fast. One must set the 0.5 hour folders option, or else the number of files accumulated in a day becomes too huge to manage, at least in a FAT disk partition.
