What are helicopters looking for when they fly over?

i've heard of equip they use that looks for hotspots in houses that can show growlights n such through the roof. may be a scare tactic tho. xD

Hot roofs, streams of exhaust, hot foundation. Meth lab in the ugly camper in the backyard,
tweakers scattering like cockroaches. You know the usual.
I have also heard that outdoors marijane gives off a different heat signature than surrounding
foliage. Who knows really?

I live near a former Air Force Base, so helicopters all the time.

envisioning tweakers scattering from a trailer into the surrounding forest as the chopper cruises put a tear to my eye, thanks for post 4:20 chuckle

Heat signatures and heavy wattage can be sensed by their tech. Also if you have a window they can use lasers to measure vibrations in the room to hear exactly what you can hear, yes including conversations.

to be frank though, if you know about them...they know about you. So by the time you figure out they are taking thermal scans or listening to your convo, you should be already destroying any evidence because you are about to be boned by our boys in blue.

They buzz our hills and houses yearly around here. Pretty rude actually. They get low and fly everyone's perimeter
like we are up to no good. Never had a problem it is just obnoxious and a gently rumbling reminder to be a good little citizen, lol

Yeah they get access to military shit so they can pretty much do way more than we prolly know.

I'll be happy to add to the speculation and paranoia
Once they establish high wattage use and a heat signature, they can use listening devises to detect the hum frequency of your ballast(s). That's why I use Lumatek electronic ballasts that have suppressed the hum. We all know how painful a suppressed hummer can be.....
