[scarface.]

hi,
could you contact me please on my email.

[scarface.]

could you please contact me a.s.a.p

[wmll]

I have a RF and AM Jamming device,s ,but they not cover all checkpoints how is that possible ?
Also Sensormatic have atleast 1 checkpoint with a build in jammingdetection

Buy the way some dutch people here ?

any info is about a fictional character i'm researching.

How do you research a fictional character?

[Jammnow]

If there is someone near to Germany i can show you an All in one device for all AM, RF, EM, RFID device...

[scarface.]

whats the price ?
whats the max range?

[upinsmoke]

I cant really understand why people would want to jam when they make a decide called rfid washer which would burn out any security tags. There are easy ways of making an mini emp which would disable security tags. Even guides on youtube.
low cost ,easy to make ,press a button ,tag goes offline permanently by overloading it with to much power.

Never try the rfid washer ,but with the camera it give a huge CLICK SOUND

true but if you modded a bug zapper there would be no noise when you set it off.

Believe me buidling a Jammer is not easy... There are few Jammer for EAS outside... I call this Jammer "go to Jail Jammer"... I tell you why.. They probaply work for 1,2,3 times but if you see how the frequency is send capacity, wave, irregular way of sweeping etc.


I have seen people coming to me back and say oh no i bought that shit and they get big problems on some gates.. So real workes need a good Box which runs perfectly without any kind of frequency interference....

And if you just think of Jamming.. There are complete military branches which are working for new Jammer.. Building a Jammer is a kind of Science! Analyzing new Gates means also spent much money for for developing a new box..

There is just 1 outside who has over 15 years experience in those devices

[skygear]

Anyone have one that they tested with an Oscilloscope?

[upinsmoke]

as someone said before ,you would need a jammer with enough signal to drown out the tags

not a specific frequency ,one that will drown it out.

A simple tv jammer "one that blocks tv signals" should be enough to drown out a tag.

they are easy to make.

A mini EMP or electromagnet possibly could do the trick.

But if it was me personally I would not be looking to jam a EAS system
instead I would look in to a denial of service attack on the system.

If you created a EAS tag and added a power source and a antenna "I mean think big radio scanner type antenna" and you turned it on in a carpark or close to the main entrance of a store ,the alarms would keep going off

after a while LP would get fedup and ignore the alarms and call an engineer to come and see whats wrong with their eas system.

when eas alarms sound too often when they break down ,its a free ticket

Good day forum dwellers, I am Russian, owner and administrator of the site on this subject, we have created a jammer RF 8.2mhz + 58khz AM, AM-free function antidzhammera, RF inhibits 95% of RF systems, test results are on the site, ready to branch English languege. 800 dollars.I glad to see you on our site!

Look, for legitimacy, a sample is requested. TO ME, A trusted member for years. As of yet, NONE of the sellers have sent a sample even after publically claiming they would.

There loss. Lots of business to be made here.

The components alone are only a few dollars. Want to sell here? Make a thread in the proper section and send a sample.

HI all

EAS frequency are not only 58khz and 8,2Mhz, there is few different as well.
I working now over jammer which cover 6 different frequency bands - static frequency and hopping in whole bang range.
In the device will be included "gate tester" which send boost power to the gate checking from distance for jammer detectors.
i hope i should show it in second part of april.

I'm affraid then they double security guards in the shop as well

[TelxonTheGreat]

I read a post on some other forum where some bored teens tagged all the shopping carts in the walmart parking lot cart returns. The carts were brought back in through the cart entrance (bypassing the towers) and every customer who took one out set off the alarm!
Reportedly walmart turned off the system until it could be fixed! so the DOS attack could very well work.

Yes you right, but it does't mean that security will not preform special tasks.
But going that way maybe the way is good idea to design circuit which will emulate signal from tag and boost it to maybe 50W power. Then you can make all the gates become "crazy" and management will switch them off. You don't eaven need to be close to the gates with that power.

[N0n4m3]

I have buy a RF jammer recently ,it works BUT there not on many gates
For now i have found 3 gates where it work ,but when bring alot off tags near the gate it triggers the alarm to go ring, so i think it,s not really powerfull
Is it possible to make it more powerfull ?

The AM jammer works like a charme, got no problems with it

Thanks

[jakoxocer]

This mini EMP idea

Forget using it on sticky tags (they can be blocked with a brass coin ! ) , like a booster bag would

Booster Foil/bag block RF 8.2mhz tags- with brass coin (not sensormatic) - YouTube

Booster Foil/bag block RF 8.2mhz tags- with brass coin (not sensormatic) - YouTube
Video: click to display

My question is :

Could a mini-emp be used on the security gate to destroy it ? Or is this too far fetched ?

[skygear]

COuld work but would render other electronics useless also... If it is in face a real EMP

lol ... asking for a sample when the price tag is $800 .. EL.. OH.. NO....

[skygear]

The device itself had only ~$25 in components. People black market these at rediculas pricing due to the nature of the device. zI would have paid for it gladly once I verified it worked.

I was in contact with them, but really. Who here can vouch for this person? No one. You really want to send $800 to a guy in Russia and have no one to verify legitimacy? Or a person like myself that can do real world testing and actually understand wtf is going on on the inside and would be able to trouble shoot in an instance of failure...

Here ar some pictures from my jammer lol i don,t know the prices off the components
But there ar really not many components on it

I have seen those coils before, on DVD safers

One is 56khz, the other is 8.2mhz, and cannot be deactivated.

I am not sure about the other components.

This is the RF jammer, i have seen the coils where you talk about but there ar match smaller

The first quastion was, wtf a alarm tag in a jammer

[mickeu]

Hi all
i Just want to show you my project:




58 kHz
66 kHz
1,9 MHz
4,75 MHz
8,2 MHz
7 - 14 MHz (hopping)

- should cover 99% of known frequencies (EM, RF, RFID)
- around 1,35W TX power on each channel.
- tests will be finished this week
- best suitable for lithium 9V battery due power consumption.

What you think about this?

[skygear]

Nice. Once your finished,or not. Post up the parts list and board file. Are you making the board yourself? or ordering them. Also are you soldering yourself or ordering them complete?

[skygear]

is that 1.35W or 1, 35W? 1 watt to 35watt range?

[skygear]

What is the antennae array going to look like? any mock ups yet?

[mickeu]

Power 1,35 - 1350 mW in my country we use , instead .
Board will make company for me and i will solder it.
As soon as is made i will post results.

[gabrielzamfir44]

You will sell this jammer? If yes please PM me...

I'm not sure where you bought jammer but sure not from me. i didn's sell online yet because is not finished. Please check from you got it and then post again.
