i understand that reflectix is good for defeating infrared imaging. how though does one conceal the heat from one's exhaust?

Cut into your heat and air system. If you have a crawl space cut a hole in the floor. If you have an attic you can go up there, but in the winter the snow will be melted on your roof when everyone else will have snow.

I thought infared detection was deemed illegal quite a few years ago. Maybe it's only California.

Illegal as sole cause for a warrant for S&S but perfectly fine for getting an idea as to who is up to what! Still bullshit IMO.

If you can conceal the signature of multiple HIDs set up in pattern through use of a radiant barrier such as reflectix (though im not sure of the effectiveness of this in the real world), the exhaust might be misinterpreted as a forced-air heater. I used a similar product in my recent build, doubling as a moisture barrier and would be interested in the real-world effectiveness in blocking the heat sig. from multiple 1000w hps lamps and ballasts.

The supreme court did decide that using flir to peek into ones house is an illegal search and violates constitutional rights. Whether or not Leo will use it anyway to get an idea of what's going on probably friends on where you live and how unscrupulous they are in your area. Reflectix looks very similar to the stuff at my hydro whore that is marketed to cover up heat signature

I have a flir scope and reflective films are useless. Not even the least bit helpful. I've experimented with it.
Your heat ventilation and the temperature of the walls, if much different than adjacent rooms are what will get you.

Dryer exaust
filter your exhaust and blow it back into your house...
Yeah, there is nothing suspicious about a dryer running 24hrs a day.
Its interesting to ride around a neighborhood with my flir scope and just see what things look like. dryer vents and roof stacks stand out in the winter, and AC units stand out in the summer. My personal space would probably get caught by a flir scope as it is an away building that has no obvious reason to be well heated and its obvious that something warm is going on in there, at least in the winter its obvious.
if they are evaluating exactly how your dryer vent looks and how often it is on, they are already zeroed in on you for some other reason.

If you have someome paying close enough attention to your dryer vent to notice, that would be the least of your concerns. But thank you for actually contributing to the thread.
kyllo is a federal decision. it only applies to one's home though. and not everyone grows at home.
you've got expensive taste in gadgets sir.
i'm not saying i doubt you, but your claim does fly in the face of the conventional wisdom. since you're in a unique position to do so, could you provide some documentation—a youtube video or something—to confirm your claim? with so many people widely relying on radiant barrier to protect themselves and their families, if you can bust the myth, you really ought to consider doing it.
cmon snoop. if i'm going to blow all that heat back into the building, it kind of defeats the purpose of exhausting it in the first place...
say. that gives me a good idea. maybe i just need to upgrade the AC and do a sealed room with bare bulbs. that would do the trick. that is, IF the reflectix works.
not sure i follow your line of reason. are you suggesting that aluminum foil is effective?
checking now to see if i can find a place that allows returns on flir scopes. maybe amazon. after i check what it can and cannot see through, i'll have no need for the damn thing.

Not at all. It's effective where a radiant barrier is needed. What you'll see through the scope is slightly less heat behind the barrier with heat leaking around the edges. If you want to hide the signature you either need to completely seal the room and THOROUGHLY insulate it, probably multiple insulated walls or raise the temperature of the surrounding areas to match. Even with the radiant barrier I'd expect to see hot spots where the lights are and the whole room showing hot.
If this is a major concern, fluorescents of some sort might be a better answer.
Heaters gonna heat
In the dead of winter that dryer vent is going to have a steam cloud around it all day. Doesn't have to be a cop to notice it, I'm sure there are some nosy neighbors out there would pick up on it.
But hey "if someone is watching you that closely you're already fucked" lol....
If you've ever watched a FLIR video thats what they look for in particular, dryer vents that run non stop, or hot air exiting a house in weird locations. You can't hide heat from FLIR, if you knew how FLIR worked your would know what Im saying. FLIR doesn't detect heat per se, it detects temperature difference. If everything in an area is 30 degrees ambient, and one spot is 50 degree's that will GLOW under FLIR.
