Title: Jamming a CCTV camera?
Post by: Kosh on August 25, 2008, 10:06:53 am
I rewatched Enemy of the State recently and that had me wondering, is there anyway to electronically jam a surveillence camera?

Cut the wire? No, that'll turn it off. :blah:

I was thinking in terms of...which movie, Speed or Speed 2. The one with the bomb-on-the-moving-bus-so-don't-slow-it-down-to-below-50-MPH scene.

The actual camera? Not likely. The connection between the camera and whichever screen it is connected to? Possibly. If it's a wireless connection, it's certainly possible, though I doubt the equipment to do it is legal in most places. Honestly, it's probably easier to just tape a piece of paper in front of it or, if it's out of reach and you're a good shot, hit it with a paintball round.

How about just jamming the camera's in Lone Star's way...

While not what you asked, I believe you can disable most (low-mid end) cameras with a sufficiently powerful laser. Seems to me that that would be far more discreet than detonating a weapon that could cause a long-term electromagnetic disturbance.

In theory, you could just get some kind of electromagnetic emitter (anything that produces powerful electromagnetic waves) and hope its powerful enough to induce so much electricity that it fries the camera or at least disrupts the video feed.

Maybe you could disassemble a microwave, get its magnetron and construct a dish to get a single, directable, powerful (more or less) stream. I wouldn't bet my head on it though and I guess high end cameras are equipped with a Faraday cage or something.

Hmm, in the new Star Wars books, they can jam a camera using the Force.
That's probably your best bet.

I think you can do it in several ways.

Pretty much any laser with more than 40 mW output will probably break CCD or CMOS pixels.

Wireless cameras can be intercepted, but so can wired cameras, if there are any connectors left outside.

A few infrared LEDs can do the trick if the camera picks up contrast only (black and white camera).  This works extraordinarily well because very few people will notice, let alone see it.  A high focus laser will take out most cameras, but it is far from inconspicuous.

Could be. I suspect some cameras still have the infrared filter inside them, though.

If it's wireless just put it in my basement.  There's enough electronic interference down there to block just about anything. 

Wonder what a hard drive magnet would do to one?

Well, you really need a very poweful magnet to get the 'OMG WTF'-effect.

A nuclear explosion will create a sufficient emp field to jam any camera.

If its wireless though, and you don't want a big mess, I think if you can disrupt its broadcasting frequency, then it should be okay. Like in Speed. They pirated the signal to transmit a looping video to the terrorist.

Sometimes, a nuke is not feasible, mainly due to logistic problems.

Oh, and wireless cameras would be bull**** if they really exsit (do they?), because they'd be easy to jam.
