Non-wifi interferers

I was analyzing a set of surveys and found some interesting interference sources. Except for the first three, they are all above 5.725 GHz which is home to the U-NII-3 (5.725-5.850 GHz) and the 5.8 GHz ISM band (5.725-5.875 GHz).

Feel free to comment if you have seen it in the wild.

This looks like Godzilla, consistent interference in a wide area, source unknown.
Possibly some video surveillance system, there are two in the area, see next.

Strong interference spilling over from U-NII-3 up to channel 136. Source unknown.
This interferer is spilling up to channel 132. Unknown source.
Different site, similar interference pattern.
Yet another site, same pattern with harmonics reaching channel 140.
Possibly a non-wi-fi security camera on channels 60-64.
