Bought in December 2014, cheap Chinese Hi3521 Hisilicon based unbranded 16 Channel Hybrid DVR (V4.02.R11.00000115. ...).
The systems functions well with my 16 analog cameras.
Downloading recordings on a computer in a local network works perfect, but... downloading files on a remote computer via internet seems not to be possible. On the remote computer you see the standard growing number of "blue blocks" and at the end you even get a message Download is finished ...but ..... in the directory specified, nothing appears.
Any suggestion is welcome.
