Sniping The Security!

Another Fine Hack For You all courtesy of C-h-a-o-s

The project:

How to remotely disable security cameras nondestructively from quite a distance?

Oh God oh God oh why:

It?s no secret. A lot of my inspiration comes from movies and for quite some time I have become more and more annoyed by Hollywoods sometimes rather silly solutions for an agent to shut down security cameras in order to remain undetected: E.g. blowing up the nearby power-plant or rigging up gadgets in sewers, where they can be detected by renovation workers and the sorts. If you blow something up or otherwise break it, your counterpart will immediately know it is sabotage and rule out a simple technical malfunction.

Another thing that got me to write this article is the abundant usage of surveillance cameras everywhere which makes me want to burst the bubble about security of surveillance cameras by exposing their weakness. Switching point of view will also often lead to improvement?

The basics:

The laser sniper project can basically be split in to three minor projects: The laser and scope with mount, The remote and The switch.

Part one: The laser and scope with mount.

For the actual disabling of the camera, I decided to use a standard laser for simply blinding the camera.

The simplicity of this construction makes me wanna weep (I think I read somewhere that the best spy gadgets are the simplest). In theory I?ll shoot it through a window using a suction camera mount as base, which also makes my contraption quite small and easy to put up almost everywhere.

Mount an ordinary sports rifle scope with the laser mounted directly on the scope and then calibrate the two so that the laser dot hits the center of the crosshair.

Part two: The remote

In the search for a transmitter/receiver solution that had both range and some sort of signal encoding (so others wouldn?t accidently trigger my laser) it hit me: cellphones? they both have potential worldwide coverage, are hardcore encrypted and since they are sold by the billions, they are quite affordable – especially second hand cellphones. So I dug out my Nokia 6280 from my ?Cellphone with SLR-lens? project.

I cracked it open once again?

Flipped the top over, removed a warranty sticker and opened up, removed the built-in speaker and solded a sound output cable to speaker connectors.

The next step is done so that the relay on the switch doesn?t sound like Fred Astaire on speed when the phone receives an SMS?
Set up the phone to play a sound only once when receiving an SMS.

Part three: The switch

What I then needed was a way for the cellphone to communicate with the laser. Since I?m no wizz at making circuits from scratch, I started scavenging the internet for a building kit that would do the job for me and found a Sound switch from Smartkit. This little gizmo reacts to sounds like claps and flips a switch

I found a small acryllic case and built in the electronics, added a grafite core to filter out electrical noise and two resistors (together 125K?) to weaken the signal a bit. Finally, I gave it an on/off switch.

Putting the pieces together:

Finally we just need to set up the laser on target, plug it into the switch, plug in the cellphone and you?re all set.
