Closet Grow heat question?

So Im about to move into a 4 bedroom house with 4 bedrooms. I know two of the closets are all interior walls. The house also has vaulted 15 to 20 foot ceilings. Do you think my heat sig will be ok? This is in a college town that has quite a few heli's flying around throughout the year and I think they may have spotted me at my old place but i harvested and quit. I say this because we noticed foot officers and cars chilling all the time. Looking for light patterns/heat I suspect. So Im hoping address change plus a year of off time plus big high cool ceilings will work better this time!
