From: To: Cc: Subject: RE: 90A-NY-3151227 (Epstein) --- UNCLASSIFIED Date: Wed, 18 Sep 2019 18:50:48 +0000 Importance: Normal Classification: UNCLASSIFIED We had a visit from SigNet technician today who gave us a better understanding of the system. DVR 1 System — Up and running. We have the password for the AMS (server that contains the software that controls the 2 DVR's) and so now have visibility into the video contained on this system through the software. I have reached out to those who specialize in DVR video retrieval for further instruction and am waiting for details. DVR 2 System — After reviewing logs it appears that there is no video recording beyond July 29th as a result of disk failure at that time. The engineers here will be reviewing the disk structures to see if there is any possibility of manually rebuilding some of this data contained on the disk array if the timeframe available is still of interest and you want to pursue it. Notes: • From what I understand there is a potential 14 day window of video. So best case coverage would be DVR 1 (Aug 1- Aug 15) and DVR 2 (Jul 15 —Jul 29) • It looks like roughly half the cameras were assigned to DVR 1 and half were assigned to DVR 2. Currently we only have visibility into whatever video was assigned to cameras on DVR 1. For those of you who were at the meeting today, please chime in if you feel there is anything else pertinent to add. I EFTA00075828
