We have setup two cams(both DCS-942L) in one of our locations. After setting up both the cams to post the snapshots to the FTP, although the functionality worked, but we are receiving zero byte images.
I don't feel there is any issue with the firewall, as Passive mode is being used.
Also, the Camera logs or the FTP logs aren't really helpful. I could see images being ftped but all of them have the size zero.
Any help or guidance on this issue, would be really appreciated.
Thanks
