Hi,
I'm interested in getting the GV-250-4. I have a question about watermarking though.
According to the FAQ on watermarking on the geovision web site, the figure says "Checksum: PASS" and "Similar Rate: 87%".
Why does it say 87%? Shouldn't it be 100% if it is an unedited original?
If a video has been edited, for example, only one frame removed, is there a possibility that it will pass the watermark test? I want to make sure this watermark feature is 100% reliable.
