Hello, I got 5216 Dahua NVR that is behaving strangely when setup for uploading motion detect video files to FileZilla server. The DVR goes into some kind of loop while constantly trying to re-upload old files that are aleady there, causing FTP server to crash. Another issue is that the NVR insists on re uploading old files that I manually deleted from the FTP server storage. There is no option to tell the NVR not to re-upload missing old files.

I found temporary work around by deleting all files from FTP, restarting the NVR with FTP option diabled, then enabling the option. It works fine for about 1 - 2 weeks, then starts insisting on reuploading old deleted files again, getting permission denied response fron FTP, then crashing the server after few thousang retries.

Any ideas ?

Same here. It gets stuck uploading the same dav file again and again, even though it has been uploaded successfully before. If I remove the uploaded file, it does upload it again and keeps uploading it all over again.
I had the problem on 215 firmware then on 216. Although on 216 at least it keeps uploading jpg files by a different thread. So at least I have full coverage of time by pictures.
It happens for me not that frequently, once a month or so. The remedy is to format HDD. Alternatively you can instruct NVR to clear files longer than say 1 day and it will self recover. But this is not a workable solution for me because my ftp channel is not very reliable, so I have to keep a history on the NVR.
