HOW ARE THEY DETECTED? HELP

[Italiano715]

OK WELL I WAS THINKING ABOUT STARTING A SMALL OP BUT I WAS WANTING TO KNOW HOW THEY ARE DETECTED. IVE HEARD THAT POLICE HAVE A SPECIAL CAMERA WHEN THEY FLY OVER THAT CAN SEE THE LIKE FUMES THEY GIVE OFF LIKE THEY SAY PINE TREE AND TOMATO PLANTS GIVE OFF THE SAME OR VERY CLOSE TO THE SAME. SINCE IM ONLY GOIN TO BE GROWING ONE WILL THEY BE ABLE TO DETECT IT OR IS THERE EVEN A SUCH THING. SOMEBODY PLEASE HELP ME OUT ON THE PRECAUTIONS I SHOULD TAKE AND WHAT I NEED TO DO TO BE SAFE.

This is what your asking about......

Law Enforcement FLIR camera

Also, you may want to watch Barry Coopers': "How Not To Get Busted"
Here is a sample of the FLIR camera. I know this will clear up that question of what it is!
