In the old days, displaying video was simple. Both cameras are monitors were generally the same aspect ratio, so it was fairly simple to display video without any problems.
Now, though, with various aspect ratios (16:9 monitors, 4:3 cameras, 16:9 cameras, fisheye streams, multi-imagers, etc.), this is becoming much more difficult.
Indeed, many VMS clients are now defaulting to cropping or warping video by default.
In this report, we look at this problem and share examples of how Axis, Dahua and Hikvision do this.
