I have an AMDV4M8 DVR and every time I set the time to UTC -8 it changes itself back to UTC -6 instantly. I can sync the time with the PC but it inevitably syncs with the NTP Server and changes itself back. I disable the NTP server, it re-enables itself.
In fact, it seems that ANY change I make to the time and date it eventually resets itself. I had date in MM/DD/YYYY format and it changes itself back to YYYY-MM-DD.
There seems to be a bug in the firmware preventing me from making any changes to date and time and this product is so new you can't even find it on their support site to upgrade the firmware.
Any help would be appreciated.
