Thermo Seeking Vans

[irconfused]

THey can spot outside grows a mile away with the right tech... They have cameras that can read the right wavelength of the reflected sun from cannabis, since it gives off a very specific radiation.

Do you have any evidence whatsoever to support that? Considering that cannabis can be any number of colors, thus reflect a wide variety of wavelengths (colors) that would make it impossible. And quite frankly if such a system exists all crops in patrolled areas would be eradicated and I know for a fact that is not the case.

As for using infrared on outdoor grows, no the plants don't create some magic heat, they are just plants. What they can use ir for outdoors is difference in soil surface temperature, like for instance if most of the earth around is a light color it will absorb less energy from the suns rays where as the almost black soil used to grow weed will absorb far more energy making it hotter and thusly emit a different wavelength of ir radiation.


On topic with the rest of the thread, If the job of that van was to look for grow houses they would not have INFRARED written on it let alone orange lights etc. If the authorities want to scan homes for suspicious ir radiation all they would need is a handhold gun and an unmarked car, which is what they actually do.

As for the person who claimed that there are systems that can see through walls this is simply not true. If you don't believe me do a little science experiment, get your tv and face it towards a wall then go on the other side and try to turn it on with the remote (which uses an infrared diode to transmit data to the receiver on your tv)

While certain wavelengths can penetrate walls, radio, x, gamma, etc, however they are not normally given off by objects so the only manner to use this would be shining the waves from a transmitter on the other side through the object then a reciever to collect and interpret what is left to paint a picture of what is going on. Imagine an x ray machine big enough to use on a house... not very practical, let alone the legal repercussions of invasion of privacy as well as releasing large amounts of radiation on people and their homes....

The only circumstances where they could gain any idea as to what is causing that heat is if you have very poor air circulation and no attic, so allowing the heat to come off your lamps and go directly up creating hot spots where the lights are.


If you have a decent size grow you will have to find some way to get rid of the heat so where you vent it will be visible on ir cameras, so just try and disguise this as much as possible (chimney, using central ac, or ???) Or for everyone out there in california the best advice I can give is to go through the trouble to get legal and unless you have a big enough op to where the dea would seek prosecution you don't have anything to be worried about

Hope that helps...

ive seen somewhere the "CAMP" (campaign against MJ plantations) know that the trichombes refract light.... and they look for clusters of UV dots....
sounded like BS, most of the footage is of idiots leaning out and looking.

Yes I agree, but also that some paranoia is good, as it keeps you on the ball

yes it does. but if it were legal then we wouldnt need to be on the security ball...as much, itll take along time of legality & price drops to stop rippers.

 

[Verite]

Evidence talks louder than bullshit paranoia.

Everyone is entitled to see the evidence they have against you.

Show me one pic/video of a flir scan of a marijuana grow operation.. just ONE.

The fact you cant find a single one to back any of the paranoid speculation talk means the world.

When its illegal to run around random searching with flir theres no way you can budget for that. When you need a warrant to flir in the first place and the fact they are notorious for giving false readings from furnaces and stoves means their use in law enforcement is limited.

If you are going to bother dumping a hundreds of thousands of dollars on flir technology why do something dumb and mount it to a van, especially when you already have a state patrol helicopter?

 

[green_tea]

im not the paranoid one... FLIR cant detect a well stealthed grow, simple as that.

the only loose ends are your exhaust and vent. get those straightened and you are golden

I'll go find a pic of the helis that can detect the outdoor crops based on the way THC works and reflects light


from wiki

Law enforcement agencies often monitor certain wider areas, particularly areas of countryside with a significant history of outdoor cannabis cultivation. In helicopters, they use infrared cameras and other equipment that can detect cannabis by measuring the heat and reflective signature of the vegetation below. Cannabis has higher reflectivity at certain wavelengths than other rural crops, such as corn. Law enforcement agencies have found that the use of this technology has become necessary in their detection efforts because many growers hide cannabis among other plants, making detection with the naked eye difficult even from the air. These techniques are effective and difficult to defeat because a plant's reflective signature is difficult to change or mask. It has been said that if the cannabis plant is planted by a pine or cedar tree the heat from the tree will overlap the cannabis plant heat making it harder to detect from helicopters.

yeah I can't find a citation for it, but speaking from the point of a scientist, its 100% possible with todays technology, and to do it cheap enough for LEO to purchase the gear

 

[green_tea]

What we should be discussing are good ways to hide your exhaust air (assuming air cooled hoods / AC exhaust)

I watched our local tv network doing a report on the new helicopter the city purchased and they put a reporter in the heli at night and showed the infared imaging system at work,showing a person walking through a park and a dog etc.
Then they came to a house that lite the monitor up like a christmas tree and the officer saying they'll report that house to the drug enforcement dept.
But... this was a pic of the attic and it showed about 6 concentrated spots where lights appeared to be.
If the property owner had put his grow in the basement there is no way the heli's system would have seen it.
PoPo loves to tell everyone that will listen how inffalible their equipment is. And if you grow we'll get you.
If your grow is one room in the basement (preferably)with a few lights no way flir going to detect you.
I'm sold on one thing and must of what I've read on this site and OG and that is if the cops stumble onto you you'll get busted. If you keep your growing to yourself it will never come out so Zip it up and it's all good

 

[green_tea]

the heli could still see a basement grow...


Concrete absorbs heat, and thus will radiate heat to the earth... so as a quick guess, you'd have a ring around your house of warmer earth (compared to other houses)

EDIT: the stuff i was talking about earlier, is a separate piece of tech that is used to detect large outdoor grows, don't confuse that with a FLIR system on a heli.

 

[Guest]

I live right near a fairly major highway and I see power company trucks with flir cameras working with choppers checking out the heat sigs on pole transformers.These choppers have flown 200' over my summertime 1800w grow and I've never been nailed.I can't however grow outside becuase they come around a couple times a year.The major powerlines for my area are about .25 miles across my street.It does suck but I know they aren't looking for me.The choppers go around in wide circles and the trucks work on the ground, I've walked right by them and seen them checking the big transformers on the big powerlines across the street.It scares ya' but we need our weed. Chaco.

Sure, but then they'd have to get a view from the side, not above and as I said picking off a 3-4 k grow would near impossible especially if the room was centered in the basement

This is exactly how this kind of goofy stuff gets spread.

Im more than curious why the police would allow the news crew to film them violating peoples constitutional rights to illegal searches which is exactly what they were doing as you explained it. You cant random flir search anyones anything without a warrant and been that way for a long time.

Im still waiting for pictures or video of FLIR used in a house growroom bust. If all this tech is out there and being used wheres all the mountains of evidence? Hell, show me one speed bump of evidence.. there should be plenty.

 

[green_tea]

no one said they were using it to get a warrant, just that they would have the drug dept take a look at that...

you can start investigations based on that, just you cant do anything in court with the information... Just like in some places you can't get a search warrant because someone said they think you grow, they try to get proof first with like you selling it to them and such.

 

[Macster2]

By the way Verite this is in the great white north and I don't think this kind of investigation/invasion has been struck down here.

 

[Macster2]

Green tea, if this took place in the states you could not open an investigation as this is FRUIT OF A POISONED TREE. All evidence gathered as a result of illegally obtained information would be ruled inadmissible. This could not be said of Canada

 

[steppinRazor]

so are we still trying to say it doesnt exsist or are you guys saying you dont believe they use the technology for growhouse detection. I saw it with my own eyes not hearsay. I had a buddy whose mom worked with the technology and had told him not to grow because of those vans. I didnt believe him at the time either but now know 2 years later it wasnt bullshit. Anyone who says cops wont do illegal searches or illegal ways of obtaining information is not familiar with the us and corrupt police or just fucking stupid.

 

[Macster2]

Yes, people and cops break the law all the time.I wonder however,how would popo justify the expense of purchasing a flir van when the information gathered is technically illegal?

 

[Verite]

no one said they were using it to get a warrant, just that they would have the drug dept take a look at that...

you can start investigations based on that, just you cant do anything in court with the information... Just like in some places you can't get a search warrant because someone said they think you grow, they try to get proof first with like you selling it to them and such.

You misunderstand.. you cant do it at all without a warrant in the first place.

Random FLIR searching houses is against the law and you can talk all the shit you want about cops breaking the law to get evidence. Show me one case where they got caught using flir illegally or even one case with pictures or video where they did use it legally.

If you all say they use it as frequent as you suggest there should be plenty of proof to back the shit talk. You can call me stupid all you like after I see the proof.

 

[green_tea]

FLIR CANNOT SEE THROUGH WALLS.

it only measures the surface temp of the walls it can see.

we already know that cops will start a investigation based on FLIR images, just that they can't use it against you in court. So they will start watching you, seeing if you deal, and who to. prolly a walk and talk at one point, etc etc.

 

[Macster2]

BUT Green tea they are not allowed to open an investigation based on flir images this is called "fruit of a poisoned tree" and all evidence gathered, starting from "Fruit of a poison tree" is inadmissable in court therefore there is no point in using flir.

 

[Mr Celsius]

Ya'll need to get it straight. Local cops wont be using FLIR and can't use FLIR. On a federal level, they can use FLIR and will. You better be doing something really wrong to even be worrying about FLIR in the first place.

If you look at CAMP, they use FLIR, but they're looking 10000+ plant operations outdoors.

 

[Macster2]

Flir was ruled unconstitutional by the us supreme court how can the feds use it unless they have a warrant
