I had to collect surveillance videos from various of private houses and businesses a lot recently. I came across a variety of NVRs many of which were a challenge for my nerves and mental health. Example 1: Exporting a 15 minute sequence of 2 cameras. After 1.5 hrs the status display switched from 0% to 1%. Example 2: This specific NVR allowed only to set a starting time for the export. The end time was chosen _randomly_ by the NVR itself. Sometimes 2 minutes, sometimes 1 hour after the start time. The 6 hour span which should be exported was done for 3 cameras in ~15-20 chunks each. I don't know what the developers of such systems were up to ... but while doing the video exports I had thoughts about flogging them in public. #rant #nvr #videosurveillance
