I've recently upgraded to a DS-7716-M4/16P, which has Firmware V5.04.050, Build 250124 preinstalled. They seem to have changed the interface such that I can't find the encryption key or stream key for viewing video via iVMS or the Web interface. All of the information that I've been able to find, on how to retrieve or setup this key is dated, incorrect and unhelpful. If anyone who has worked on setting this up can enlighten me as to where and how to configure this, I'd really appreciate the info! Thanks!
