Ok I read a few replies and just thought I'd post instead of reading all, may have been answered already. Well for one, it is ILLEGAL for police to use an infrared camera on your home without a warrant (well in canada, I am sure UK has similar civil rights tho). 2. What is the difference if you are using 1K HPS or 2 of them to grow dope or grow vegetables in a hydroponic set up besides being a bit more paranoid . 3. Infrared detects heat given off by objects. If the room or place you use for growing is bound by walls the infrared will only pick up the heat escaping through the walls, which will be relatively evenly distributed except for at windows and the spaces between window and wall, where there will be a bit more variance. It is not going to be like superman and be able to xray to the precise levels of your home.

I think when police use the IR camera it is more to see people who have like readings of 120 deg f or like 35 deg C becuase clearly people cannot live in those temperatures and it is qiute evident that it is being used as a commercial grow. If a room is raised a few degrees from having a couple lights though, if they even can pick up on it, wont even think twice about what might be going on.

Edit: check this out, im sure there are plenty more on the net but yeah IR doesnt penetrate thick walls unless your house is made of plastic

Anti detection foil Vs the police ok so this might sound abit weird but i felt guilty coming on here and telling people that i am gunna start growing, ya know 'the less you know the less the old bill know' but i needed 2 ask a major question, does ADF really work? ive seen it around on many websites, and ive gotta say it is majorily expensive (around £5 psm) but there are many people that say the police infra-red cameras can see through it, and that the police don't necessarily look for where the lights are, but where the heat Rating: 5
