Beating IR camera's how?

[dazzerx2000]

Hi ICmager's,

Ive been reading on police chopper IR camera's and what allot of people say is a good way to avoid detection by them. What i have noticed is that allot of people seem to have good growing locations to grow in from the start e.g. basements ect but as we all know this isn't always possible.

Im thinking of buying some ADF but am un-sure as to how to use the stuff properly for example ill explain the room i want to use it in more detail. The room is a upstairs bedroom in a three bed SEMI detached house and its measurements are 4meters length, 3meters width by 3meters high, there's a chimney stack in the room which im planning of knocking through and venting out into that leads to the roof. Now ill be using adequate extraction in the room but even with the best extraction there's going to be a heat signature that's not showing up in other parts of the house, also the room within a room is a good idea but i would like to avoid doing that if possible as it will just kill allot of space and make moving around awkward, also that method is only good if you can cool the outer room your inner room is in which means A/C which isn't an option.

Now the loft is insulated with roof insulation so heat rising to the celling in the grow room should get trapped long enough in the room for my main extractor fan to remove, i was thinking of setting the foils up as listed below:

Mylar on the wall that's closest to the internal part of the house e.g. bedroom back wall!

Mylar on the 1st side wall that leads to my neighbours house

ADF on the 2nd wall that leads to outside at the side of the house

ADF on the outer bedroom wall leading to the front of the house

Does this make sense is this how you would all use it as im sure ADF is not needed on all four walls and the ceiling in relation to how a chopper would be looking at the property???

If anyone can help let me know thank you.

before you go through all that trouble.....vent all hot air down under your house, if not, they are going to wonder why hot air is coming out of your chimney in the summer

 

[lysol]

They cant see in thru your house, unless maybe you were running like a few k watts in a concentrated spot. How they get you is when you take all the heat and vent it out your roof, then you have a huge plume of hot air that shows up on FLIR

 

[dazzerx2000]

hi growshower is that not just allowed anyhow as cookers ect vent out of there anyway....i should have said im based in the UK so our houses are allot different to American builds and are not raised off the ground in the same way. Also our summer can be equated to 3 days of sun shine at a temp probable close to your coldest days in summer where are you based?

If from a colder climate country then how would i go about venting under the house from top floor bedroom should i just run the hose down the stairs and pull up a few floor boards i was planning on living in the house but might have to rent some where else to stay if its gonna involve noticeable work like suggested.

 

[dazzerx2000]

lysol i see what your saying the lights will be in the same room but not really close when you say "vent out of the roof" do you mean venting into the actic and letting the heat seep out of the roof through the tiling ect or are you referring to a chimney stack which is a source for heat like a dryer vent?

the big plume of hot air doesn't sound to great most people here vent out of a window that's boxed off with wood and left slightly ajar but ive never liked that idea. So are most of you going out undder the house then how are you all doig things then?

buy yourself a secret jardain tent. problem solved.

 

[dazzerx2000]

Hi Aeroguerilla not sure i understand your answer ive looked at the secret jardain tent you recommended and they look like there something to be used with a 400w hps or similar in the room size i posted above something like 6x1000w would be used also i think using one of them tents would class as a room within a room and the reason why that isn't such a good idea was noted in 1st post but thanx for your support thou.


if no ones got any other suggetions about venting options whats your thoughts on the use of ADF if i were to use it have i thought about its use in the right way, regarding to which walls should be coated.

 

[Aeroguerilla]

dude get the mammoth grow tent, its 10x20' infared proof. im working with the 10x10 and a 5x10 attached and it holds 6k no problem. warm air is nothing, the center of the light bulb is what they see when they use the gun. the warm air could be a whole number of diffrent things

 

[dazzerx2000]

thanx ill check google for the bigger sized tent my first search only returned the smaller ones sounds like an idea, didnt think the IR cam could see the shape of lights through brick as il be masking the windows with wood as well figured it would just be a warm red wall.

Just an idea but commen sense says run during the day if possible and climate allows. During the day the street outside your house will produce as much IR as 20,000 watts of lighting dumping out of your houses roof and will not be seen during the day. Most Law enforcement will use IR at reasonable hours in which the sun has gone down and the ambient heat created on the surface of objects by the sun cools. I.E. 0300 to about 0500 this is not proven but I have had many experiences with IR and know the basics... Now depending on where you live farther south meaning hotter days and less worry at night. Run lights at 0600 to about 1200 veg. This not being bad usually because most situations call for far less light than flower meaning less overall heat signature. Anytime for your 12 hour cycle of flower where most of your heat will be produced by more lights should be ran during say 0700-1900 or so on you understand im sure...

 

[dazzerx2000]

yeh that's an idea running lights in the day i think i will still need A/C anless during the winter time i might stop growing during summer months and run lights in the day during winter time as the price in the uk for electric per KW is stupid you can quickly out price any bud produced by using A/C and large wattage's i think last time i checked we were on around 15p per KW with 17p being the highest ive seen that's 4.5x overseas rates

 

[lysol]

if your foundation is concrete slab thats a no go, how much watts is it and how hot does it get by you? The highest security method is to just spread it thru the house and use an A/C

If you want to be more efficient you compromise security, you could vent into an attic it just depends it wont take as much heat to see thru your roof as it would to see thru the entire house is the thing

thanx ill check google for the bigger sized tent my first search only returned the smaller ones sounds like an idea, didnt think the IR cam could see the shape of lights through brick as il be masking the windows with wood as well figured it would just be a warm red wall.

They can't, not unless they were able to single you out and get the perfect angle to look, even then < 1500w isnt really that much heat if you have some air moving over the bulb. If they are singling out your house with FLIR youre already busted anyways, just dont have like 5k of lights sitting around without air cooling and dont vent hear out that would be obvious on FLIR

I just posted this in another thread. www.youtube.com/watch?v=sudf5xDIhmM

FLIR isn't X-Ray vision. It reads the temp differential on surfaces.
Don't provide extra heat to the exterior walls, foundation or roof and you're invisible.
Easier said than done

Whots ADF again , is it anti detection foil of something ?
Hi dazzerx2000 there are 3 types of heat transfer , conduction , convection and radiation . that mylar only stops radiant heat so it's insulating properties are poor . it's more suited for reflecting light in the growroom .

The best insulaton works on a closed cell principal , like an aero bar .
Pockets of air , or a cavity . I'm not sure about IR and detection but i do know a bit about insulation . 50mm foil backed fiberglass on said walls would stop heat transfer , containing it in your room , or two layers of 25 mm with staggered taped seams .

Wood is an excellent insulator as is perlite or coco .

A friend got caught in the UK recently growing in an outhouse, Pigs were a bit cagey about what exactly had gone on, they were muttering about Helicopters and most of us [his amigos] think that was right - he vented straight out of the side of his outhouse in what FLIR must have thought looked very funny - and they are always around the area chasing after the local Pikeytards in stolen cars etc.

I have never had a problem with a Chimney, it looks normal if you think about it. If you are unlucky enough to get Helicoptered on one of the 3 hot, sunny days of the UK summer, it aint going to be that different to any of the other Chimneys in the street. I know of 5 gardens in London right now that have never had a problem, one had a centrifugal fan running in his mums loft for 16 years, continuously.

 

[dazzerx2000]

thanx for all the reply's my minds at rest more now im definitely going to just use over the top extraction in the room and vent out of the chimney stack, ive been searching on it and it appears to be one of the best if not the best place to direct heat and is expected to show up on a IR camera as a heat signature. Im going to avoid any type of heat signature in the loft thou, i think the defacto position for canna gardens is assumed to be in the loft.

bongoie thanx for the heads up on the different types of insulation's ill try and find the foil coated wool/foam stuff from a local supplier failing that thou ill just use the ADF as its better than the other types of mylar at reflecting heat, and it is mostly radiant heat that is emitted from the lamps so its better to stop it there before it gets absorbed by my walls and becomes insulated heat.

 

[dazzerx2000]

hi ChaosCatalunya sorry to hear about your mate, my heart drops every time i hear of a fellow grower getting busted that's just bad luck especially in a outhouse as if im not mistaken there just like extensions built onto your home most people have them at the end of there kitchens purposely built to house washers/dryers ect im surprised the SLIME busted your mate for venting out there as if i had a dryer in the same setup i would be to.

 

[bongoie]

No bother , look for kingspan also that's the foam type foil backed , its easy to work with . all ya need is a saw an tape . a great insulator http://www.insulation.kingspan.com/uk/k8.htm#
Go with two layers and staggered taped seams .

Have you ever thought about venting into the sewer? Unhook your toilet and vent all hot air into the pipe, it will certainly get rid of all that heat for ya. Be safe!
