iPad screenshots work fine unless the shot includes a camera view

I’ve seen this question before, but people are always referred to Apple Support. I would just like to know if anyone else has my issue. I do screenshots just fine on my M1 13” iPad Pro unless I’m looking at a security camera. Let’s say I’m watching someone break into my house over a camera, and he looks right at the camera. I take a screenshot so I can have a great picture of him. The screenshot is completely black. This happens on 3 different brands of cameras. Please don’t misunderstand and focus on why I would do the screenshot when I can hit record on the camera. I know how to do that. I just want to know why the screenshot is black when a screenshot works just fine at other times. Here’s what it looks like if I screenshot six of my cameras in HomeKit, and those are snapshots only 2 or 3 seconds old.
