Issue

Hikvision Local Settings

Videos and snapshots downloaded from Hikvision DS-7604NI DVR cannot be located in the locations specified in DVR Web GUI Settings. The files seemingly download successfully, there is even a pop-up showing where the file was supposedly saved.

At some point, I enabled share encryption, which reduced transfer speeds by about half. It was chugging along like this for quite some time but then noticed that speeds got even slower. After a quick test, I found that upload to an encrypted share was lingering at around 10MB/s, downloads were maybe double of that.
