Get yourself a flir scope

[SOTF420]

It's not really just the hot air it's the infrared heat energy that is ABSORBED by surrounding structures in a grow room since it easily passes into other surfaces and heats them up so they glow on the scan compared to the surrounding structures. Like the walls the light hits for instance, basically the whole room absorbs the IR heat energy and glows like a lightbulb at night. If you look through a covered window with FLIR you can see bare bulbs in vertical grows if they are not inside reflective hoods. You can see a 1000 light right through a roof with a high grade FLIR setup like the ones on the choppers it stands out like a sore thumb if it's not properly shielded.

So if you want to beat FLIR it's not just heat you need to worry about it's IR light from HID's and even if you kept the room the same temp as the rest of the house the room is absorbing the IR spectrum of light from say a 600 watt or 1000 watt HPS. Like the name say's "FLIR" Forward looking infrared radar not heat detector they can use a laser temp gauge if they want to see what is hot or cold on a house. IR is non visible to the naked eye far red energy spectra so just remember that cooling your room is not enough to protect against this being visible you must BLOCK the IR transmission into surfaces and barriers or it will surely still be visible.

now imagine flying around in an airplane for the day with that thing? im sure you could spot a few 100 indoor ops

Funny story for the tree man.

My dad had a shop when I was born so growing up a gear head was second nature. If anyone knows donut shops and motorcycle shops have a way of attracting law enforcement. One day these off duty fellas came in and he was talking about running around in the helicopter spotting patches and my dad was like bullshit how the hell you gonna see a bush and know what it is so far in the air.

Well the guy took offense to this so a few days later he invited my dad to go along for the ride.

Dad came home shaking his head saying it took them about 20 minutes and he spotted several patches and they were 1500 feet in the air and he did so with his eyes no flir no scope just experience and a good set of eyes.

The drones are what will get us. A simple fly by will enable them to tag houses and start their investigation IF THEY WANTED TO mind you. You can get 2 drones for the price of ONE car so pretty soon they will be everywhere and let's not forget about the new internet thats will be coming our way by years end.

So what do things look like? My understanding is that higher end flir scopes arent different in what you see, they are just higher resolution meaning they can see things from farther with more the same detail as this one sees closer.

My setup is a big away building like a barn in the back 40 with a small part of one storage room sectioned off with a fake wall and a hidden door to get in. I run a lot of watts for the small space, currently about 2000, 1000 LED side lights and a 1000 air cooled HPS overhead. The space is cooled by a big window unit.

So you can easily see that the exterior walls are mostly cool but the space that is sectioned off is hot. So it is easy to tell that there is a partition and something going on in part of the storage room that isnt going on in the others. during the day when the sun heats things, it isnt obvious, at night it is. You cannot see any detail of what is inside, and my walls are not insulated at all, just particle board, house wrap, and then cedar exterior wood. I don't think anyone can make out whats specifically inside. Even glass blocks the view, meaning if you look into someones house through their window, you cant see specific hot spots, like a light bulb, but the whole window might be hotter or cooler than the walls, and you can see leaks as hot or cool spots.

The vent output of my space is under the eave at about 10 feet off the ground. The wood around the vent outlet gets hot and when its cooler outside you can see the airflow itself coming out. It looks about like a dryer vent.

As I play with this and look around the neighborhood, there are tons of vents that show up, mostly dryer vents and vent hoods from stoves, and the stacks on the roofs. I don't think one could easily tell such a normal vent from a grow room vent, unless they were already suspicious and scrutinizing it.

I don't know enough about what the high end scopes can see that this one cant, but from the literature it says they are the same except for the distance increase. And with this scope you sure cant see whats goind on through the walls, you can see if the walls are hotter in one place than another, and someone might be able to draw conclusions from that.

Now if a small house was venting thousands of watts of heat, it would certainly stand out. Fortunately, my grow is back in the woods, so you have to already be deep in my land to see it at all. Then again, there is no excuse for having a hot spot and a hot vent on a barn. Thats not why I bought it, but it a fun exercise that might help urban gardeners in places that the cops use this device to find people.

Easy to forget these systems work equally well in full sunlight as in the dark .

Some genuine FLIR images appear to reveal lights through the roof structure of the building , could easily spot distinctive sodium spectra which would look unusual in a residential attic.

The current high end military kit will inevitably filter down to local police helicopters/drones , would it be practical or paranoid to cover the lights with roofing lead to stop the point sources being seen from above ?

Forty kilos would cover two square metres and most reflectors could be reinforced to take it , good firebreak too.

Here's some plastic shielding....the room in a room with the outside of the inner room lined with this stuff and checked with a flir might work...

The thing i have always said in response to flir is "who's to say you are growing MARIJUANA"??? Tons of people grow legal plants....

ALSO...

all toolbags do not forget about picking up an RF scanner to go along with ur FLIR...

im pissed that this thread was even started to be honest....

Lord only knows how many sock cuckin crooked "icmaggers" will go out and use these products maliciously....

if you are thinking about investing in flir (in order to spot other outdoor grows) this season instead of investing in a grow of your own then you got another thing coming lemme tell ya.....


in response to the title of this thread: DONT Get yourself a flir scope.... put them fucks out of business...

go buy some seeds, fuck the flir

Buy some quality LED lights with no IR in them and far less heat, fuck the flir!

Thanks...a nice tool for sure.

So a month ago I bought one of these new FLIR© PS24 thermal imaging scopes. They are finally "cheap" enough to be a consumer item and it fits in your jeans pocket. I got mine for about $1800 by shopping around.

So what's it good for?

You can check your heat signature and know how obvious you are, and take measures to fix obvious heat signature issues.

You can find people in the woods at night and use it as a security device for guerilla outdoors gardening. You can't easily use it to walk a treacherous path in the dark but you can scan about and be pretty sure no one is in sight so and then turn on your flashlight. It can be used to walk around at night, but its not head mounted and doesn't always show terrain well. It does make mammals stand out even if they are hidden in the brush or cammo.

You can use it to suppliment your personal security. If you hear bump in the night, you can quickly scan the area and people stand out pretty easily even if they are hiding. And all the while you can stay dark and hidden.

It's a neat new tool.

not a bad idea.

 

[foaf]

Its not that simple for sure.

I have 2000 watts of LED in my grow space, and they give off plenty of heat. sure, less than an HID, but the exterior walls of that part of the larger room light up hot for sure, and its fishey looking through a flir and would give someone reason to wonder, if they were already curious enough to be fliring my building.

Leds may spread out the heat evenly, and not make as much heat as other lights, but they make plenty of heat. They have built in fans and heatsinks for a reason. The main reason people think its less is because people rarely have 1000+ watts of led, as they so often do with HID lights.

"In 2001, the United States Supreme Court decided that performing surveillance of private property (ostensibly to detect high emission grow lights used in clandestine marijuana farming) using thermal imaging cameras without a search warrant by law enforcement violates the Fourth Amendment's protection from unreasonable searches and seizures. Kyllo v. United States, 533 U.S. 27, 121 S.Ct. 2038, 150 L.Ed.2d 94 (2001)"

Of course, the pigs don't always play by the rules, do they?
