Can someone tell me what this image mask is?

I Had a home intrusion and a baby monitor recorded someone on my computer, i was digging around looking for "install dates" and a few times matched up with the event... One was titled "image mask" and I've posted a big chunk of it belowmy about 1/5th of the whole thing. Based on a search of the file type it looks like a Motion file, could this be an overlay of some sort? Anything you could tell me would be appreciated;
