I followed the instructions in your support "how to" to set up my Amcrest 722S. One picture every five minutes is my camera's FTP schedule. Nevertheless, the Amcrest configuration only allows for a maximum upload interval of 7 seconds! Even though CameraFTP allows the upload to proceed, the allocated space is eventually filled, and the photographs can no longer be uploaded to CameraFTP.
I contacted Amcrest, and they informed me that "custom" timing is not available, despite their website support page saying otherwise. They were of no assistance.
So now what?
