You have to think of a way to hide heat. Good luck.
I will say that you are not likely to have a problem from leo and thermal gear.
Unless your selling alot, or growing with some very big lights, your fine.
I mean, like 2k in a house will make the roof area of that room glow while the rest of the house is cooler.
Thats it.
Thats what that stuff does. Whats warmer than the surrounding area. Problem is heat is super hard to hide. You need thermal gear yourself to see if you are safe. Like I said, only 3-4k grows really need to worry.
If in the winter, all the roofs in the nieborhood are covered with snow, but your have a dry snow free spot over your garage/what ever, that might be a good spot for thermal.
I really dont think they fly around random spots with that stuff, fuel for choppers is not cheap, and they have better success snooping on houses they actually have info or tips on, rather than drive around looking for a 600 watt grow. If your under 2k, your fine.
