IR Used to Defeat CCTV – Follow up

Following on from the previous “IR Used to Defeat CCTV” article, below is another video showing, once again, how easy it is, for those with intent, to defeat surveillance systems.

New Home for Where is My Data

This site has now been incorporated to the site Where is Your Data?

This blog will still remain here, but lectures, quizzes, tests, and news will be put on the parent site.

Laser Used Against CCTV

Lasers have been looked at defeating CCTV cameras with a vareity of different reports on the results. One of the main reported problems is that laser are too directional, and as such if not pointed directly at the CCTV lens do not work.

Hence people have used an arrary of IR LED lights to resolves the direction issues.

One post report the used of a laser used to defeat CCTV that was activated by a mobile phone, the idea being that laser is fastened into position prior to it being activated –  obvious that assumes that the laser and CCTV camera are both fixed and will not move.

More bodyscanners in the US

The US are to increase the number of “body scanners” at airports, which give the operator a “naked image” of person being examined from 40 to 120.

The devices can cause controversy as the allow the images of a person to be take that they probably would not normally want to be taken.

Bloomberg Article

The U.S. Transportation Security Administration will triple the number of devices at airports that can detect bombs under airline passengers’ clothing.

The purchase of 80 so-called Passenger Imager machines will bring the total in use next year to 120 at 21 airports, agency spokesman Christopher White said today.

The imagers are produced by L-3 Communications Holdings Inc., OSI Systems Inc.’s Rapiscan unit and American Science & Engineering Inc. The TSA hasn’t yet decided which vendors it will use or how much it will spend, White said in an interview.

IR used to defeat CCTV

We are repeatedly told the CCTV is here to protect us from the worst of the worlds offenders, including terrorists and international criminals. Despite the obvious flaw in the argument that suicide bombers are not bothered if they are filmed blowing themselves up (especially as they normally release videos to that effect shortly afterwards anway), there is the additional issue that if a person wants to hide their face from a standard CCTV camera it is incredibly easy.

A person can hide their face with a beard, material (mask/bandanna/etc), or they  can go slightly more high tech and use infrared lights.

A single point source of a IR Laser, if pointed directly at CCTV camera will flare the camera, however that involves a laser and the user to point and hold the laser directly at the camera. However, if the individual uses and array of IR LEDs then the effect is the same, as a single directed laser.

The idea is relatively simple, the user places IR LEDs in a “head torch, such as the one pictured inset. IR LEDS can be bought for just 79p and  LED head torches can be bought for just under £5 .  IR – Infrared - with a range of 750nm to 1mm has a range below the human eye, but can still be detected by CCTV cameras.

Below are the effects of using this type of  technology. There are flaw in this anti-CCTV devices. The LEDs need to be powerful enough, the and CCTV camera needs to not have an IR filter. It is is also possible, to enhance the blue green specturm after the incident to try and recover a better image.
