[ARCHIVED THREAD] - Defeating a IR camera (Page 1 of 4)

A buddy of mine called me this afternoon to toss around some ideas on disabling a IR camera his neighbor put up that hits said buddies door.
This bugs him and he wants it gone. I guess talking to the owner wasn't a option for whatever reason My ideas were 1. Push it out of alignment with a broom handle after finding a non covered area to move into position 2. IR laser shined at the lens 3. air rifle Any other ideas? (No he's not planning a heist...at least I don't THINK he would toss away a LEO job that way) |

Quoted: Run an infrared bulb right up to the property line and light it up! You would really only need to have a bright IR light outside of your door. If it were bright enough the camera would probably be all washed out. You could also hit it with a blue laser like the wicked laser stuff that they sell and that would most likely kill the sensor in the camera quickly. That would be destructive though so you would have to check your local laws there...

Run an infrared bulb right up to the property line and light it up! This. If you buy the a quality light with the right wavelength, they won't even be able to see it. It'll just blind it. Lower quality stuff will be visible to the naked eye. Like cheap cameras, they have a slight red glow. |

Quoted: You can get some cheap component LED's and solder them to a board for next to nothing. Quoted: Quoted: Run an infrared bulb right up to the property line and light it up!

| I'd stray from braking the law when there is a good chance the guy will have video of you/buddy trespassing, destroying property..... How about park something or putup a fence or short Trellis for flowers that blocks the view. If a new camera shows up to look around it, call the cops. |

Take a large sheet of some material and paint it a single color. Paint message on that with a visibly similar color that absorbs differently in IR spectrum. Maybe something inquiring as to why he aimed it there, a snarky comment, or an invitation to come over and view your fine tapestries and etchings.
Or just overwhelm the camera with an IR flood. Posted Via AR15.Com Mobile |

Moving your security devices around as they please, whenever they please 2. Directing an IR laser of unknown power at your family's eyes 3. Shooting an air rifle at your property. Got it. |

Put up on of these and point it at the camera. It won't damage anything but it will wash out the camera feed at night. 198 IR LED Night Indoor/Outdoor Long Range 400-500ft IR Illuminator  |

Put glass in front of it. Glass blocks UV not IR. Actually, glass blocks long and medium wave IR, thence the need for expensive gallium arsenide lenses. Near-IR and SWIR will behave more like visible light as they approach the visible spectrum. Posted Via AR15.Com Mobile |

I'm only familiar with it from what the sun throws at us. I should add that it only blocks UV-A too.

your typical chinese green laser pointer starts out as a IR laser, the beam is pumped through a crystal to increase the frequency, and then split to cut the frequency in half to 532nm green. better quality green lasers have filters to remove the leftover IR. cheaper green lasers rely on that leftover IR to bump up their power specs (5mw green is actually 4 mw green plus 1mw of IR).
how this helps you. green laser, mount it and aim it from anywhere secure, you can see the green clearly to aim. drop a ir pass filter in front of it, the ir pass filter will remove the visable green and leave only the invisible IR. the leftover IR will typically be 20-40% of the rated power of the green laser. 5 mw green dpss will leave you with 1-2mw of IR. you can test it with a digital camera, which will see the IR as purple light.

Camera can't see into his house. If he's an LEO he won't be doing anything crazy in his front yard. If he goes on vacation & comes back to a robbed house, the friendly neighbor could help him out. |

did the neighbor ever give a reason for doing it in the first place? if it's obvious that the camera is pointed for the express purpose of watching your buddy's yard/door/whatever, then game on. I'd start by putting a camera pointed at HIS yard/door/whatever. see if he likes it then.

I'd aim an IR strobe/illuminator directly at it, and put it between my door, and the camera (if there's a fence, mount it on the fence, between your door and the camera). The strobing would mess up the auto-iris (or electronic iris), and the "wall of light" effect will cause him to be unable to see anything behind the strobe.
Make it pulse/strobe slowly... every 1-2 seconds. The camera will be constantly adjusting to the changing light conditions, and it won't be able to produce much in the way of a usable picture. Use a cheap 12VDC IR spotlight off Ebay (narrow beam, pointed right at the camera), and use one of these to make it strobe: Link 
I've never made one, but it seems easy to me. |
