Hey OP, if I might make a suggestion to capture this stuff? I have a $20 web cam out in my carport...it's one of 3 I have around the outside of the
house because my home office is so isolated sound and window wise, you could kick my door down when I'm working on something with audio, and I
wouldn't know it otherwise.
How this relates to this is simple. Again, this isn't a surveillance camera...It's a web cam from Big Lotts and it's been running out there for 5
months now. All weather....(although under cover)
I have to adjust it a couple times through the day and evening....but you'd be surprised at how clear it is, even on a dark night. Even cheap cameras
have light collection routines now that blow my mind for clarity compared to my own eyeballs.
How this can help you is that what I have there records 24/7 on a self erasing loop running over a 7 day rotation. So..if anything of vague interest
may have happened in the last week? I got it.
Motion sensor and lighting settings to trigger recording (as opposed to 24/7 to a hard drive) make
the file sizes much much smaller....but still manage to catch everything.
What makes that particular software great is that it's running a buffer automatically. So when I have it on motion setting? It kicks on record when
it picks up motion....but it starts that file from several seconds prior to the detection. ...I.E.... Your sky flashes, if the cam is aimed a bit
differently and tweaked for night time recording, would easily trip it and make recording that 100% fully automated. All for about $20 on my cost
