right... this is a beautiful idea and i am jelous of it but this is running through my mind at the mo.
I just watched a program called Cannabis: Britians Secret Gardens... They were saying how easy it is for a police helicopter to pick up grows (they catch 8 large grow ops in the UK every day...) Unless you can keep that warehouse cool and explain why there would be any heat in it/huge price in electric bills, id stick to a grow in your house...
That program sure opened my eyes... who knew that every grower has a red/white heat spot on their roof, even if they are growing in the basement...
The information in that program you watched is nothing more than scare tactics...I use FLIR cameras at work and have received training from the manufacturer in their use....I can assure you, the only way the fuzz could see a hotspot on your roof was if you HID light was mounted in the attic. Or in a second floor room that isn't insulated from the attic
The red/white dot would be the spot the light has warmed the roof.
Infra red cameras can only see heat, they can't see through things like an X-ray, not even glass. In fact, a clean window that is in direct sunlight will show up on the camera much hotter than it actually is. This one of the reasons why the fuzz has to scan at night during the summer.....
