The Common Intermediate File Format (CIF) is referenced by nearly every DVR/NVR manufacturer, yet the vast majority don’t conform to that standard. Instead, some conform to the Source Input Format (SIF) standard. Some don’t conform to either, but still claim they record at CIF, 2CIF, 4CIF, etc… “Come on Larry, you’re just picking nits.” You’re damn right I am, that’s my job, and there’s a significant difference between 352 x 240 and 352 x 288, especially if the perpetrator that just murdered someone is depicted in that image. Do you have any clue as to how that video should be displayed at the proper aspect ratio? If it’s evidence, I sure hope you do, but I don’t blame you if you don’t.

I could drop names of several DVR/NVR manufacturers that have incorrect specifications, documentation, and training materials, but what’s the point? I’ll tell you the point; don’t trust DCCTV specification sheets or what is reported by their software. Period.
