How to Blind a Camera Using a Laser

In this article I am going to explain to you a simple mechanism that you can use to blind a security camera, webcam, tv camera, camcorder, and most other optical recording devices. The idea is very simple, when a powerful laser is pointed directly at the lens of a camera, the lens is overwhelmed and cannot see. However, it is very difficult to precisely aim and keep a laser still from any practical distance. Here, I will show you an easy remedy for this problem.

    Materials


  • A powerful laser, can be any color that you choose. Your range will depend on the power of your laser. (I suggest the C.O.R.E. by Wicked Lasers)
  • A gun scope, binoculars, golf range finder, or other magnifying eyepiece. In this article I will use a gun scope.
  • A small tripod.


    Construction


  1. Start by attaching the laser to the gun scope in a fashion shown below. You can use any means of attachment that you want. Duct-tape, super glue, rubber bands, or string work well. Just make sure that the laser is on snugly and can be adjusted easily.


  2. Attach this unit to your tripod. Make sure that the whole unit is steady and well attached. If you plan on using this unit outdoors, it might be helpful to cover any critical components with a plastic shopping bag.




    Use


  • Before any use, the scope and laser must be properly aligned. To do this you should position the unit at the approximate distance from the camera that you will be using. Looking through the scope, move the laser into the center of the crosshairs, and lock the laser into place.
  • Move to the location that you are going to use, it is best to have a straight shot at the camera.
  • Look through the crosshairs and aim the unit at the target camera.
  • Turn your laser on and fine-tune the positioning of the dot onto the camera. You should know that the laser is aligned properly because the laser will cause a glare when it reflects off of the lens of the camera.
  • Lock the laser into the "on" position. This can be done simply by taping the button on most lasers down with a piece of strong piece of tape or tightly tying a piece of string around the laser over the button.

    Effect


    The following are demonstrations of the effect in action. Note the improved effect as the range is decreased. Also, using a green laser like the one mentioned above from Wicked Lasers will result in MUCH better result.







    In my experiments using the C.O.R.E., the results were much better. The camera was completely disabled and all that resulted was a white screen. This was from a 15m range using a Microsoft WebCam. I would highly suggest using at least a 5mW green laser over the 1mW red lasers that are shown in the above picture. For an ever better result, you could use a combination of red/green lasers, which would making filtering the image nearly impossible.

    Wouldn't it be better to use a infrared LED? because it's doesn't have to be pointed at the camera?

    the Thats so cool, but that reminds me, did you hear about Hand-held laser tool assists the blind

    For the approximately one million legally blind and estimated 200,000 totally blind individuals in the United States, the importance of improved tactile and visual tools to enable mobility is paramount. For more than 30 years, the blind have had access to commercially available electronic travel aids (ETAs) such as ultrasound sensors and other sonic-related guides. Another family of “sonification” devices aim to encode complex geometrical and topological information into acoustic or tactile stimuli; however, these devices are not practical as mobility aids because of reduced spatial resolution and the difficulty in interpreting the sonified three-dimensional data.

    By considering only one-dimensional data from a hand-held noncontact ­device incorporating a laser and camera, researchers in the Department of Computer Engineering at the University of California (UCSC; Santa Cruz, CA) are using techniques developed in the robotic field for the analysis of range data from a rotating light-detection-and-ranging (lidar) instrument to develop a more compact and economical “virtual white cane.”

    for god, wickedlasers are the worst lasers ever, and to get this efect all you need is a 200mW focusable red laser sold at 40% on dealextreme, you disfocus it and aim at the camera and you will get the same or even worse blind camera. Even if you aim at it focused without a tripod, a very fast hit will permanently damage the camera wich may suit your needs better.

    Forgget about buying in wickedlasers and tripods and scopes and shits lol

    Hey it was fantastic really but as I think most of the crimanls may misuse this technology...

    Russell Reed said...

    I'd like to know the best laser color to blind security camera.

    raymeds said...

    One major limitation of this method is the fact that most lasers only emit one color, therefore it is fairly easy to filter the color using optical and electronic methods unless multiple colors are used. Another limitation may involve exactly how to locate cameras, as they can be hidden anywhere.

    Would not it be easier to work with a home LED? as it's doesn't have to be sharp in the photographic camera?

    This is so cool! I might be able to use this to destroy the camera devices in greedy corporate centers.

    i enjoy your writing ,its so readable ,pleasurable and easy to read .. thx .

    Could be used to blind the cameras on the drones that our government are launching to watch us and our every move. I hate the Idea of the government beaing able to see everthing I doo in my own backyard even if it is cooking a steak.

    Unless you live on a military installation, I'm sure there are no UAV's or SUAS's near your house. Yes I'm being literal, but its difficult to get a restricted operating zone in the continental United States.

    And good luck trying to hit the nose camera on aUAV, traveling at 85 mph at 25,000ft AGL. ��

    "lovemyfreedom " i totally agree with you on using this against drones and i think it is one kinda technology used for drone counter measures but the big question is how do you know it exist in the near by area? and how could you aim to the EO sensor ? big challenge i wish if we can brainstorming these how questions.
