I was just wondering how much wattage would be necessary to burn out a cctv camera? Lets just suppose that the hypothetical camera is behind a domed plastic cover or flat piece of lexan. Im assuming quite a bit of the lasers power would be wasted passing through the glass/plastic housing. Has anyone done any testing in this area?

I know that lasers of that strength are very dangerous and that they will instantly blind you even if you are hit by a reflected beam. Dont worry I'm not building anything like this nor planning to.

I read that most digital cameras have an "f-stop" that is designed to protect the CCD chip. So the laser must be powerful enough to do serious damage to the ccd in a short period or the camera must be exposed a few times after the f-stop resets. It seems green lasers are best suited to this purpose...
 





This site gives some good info. Unfortunately he is only interested in temporary disablement of the cameras. Im think more along the lines of a making the CCD nicely toasted.

I have to say that this sounds like one of those uses for a laser that really - I can't see any constructive end to. At the least, it's vandalism. At the most, it's a way to prevent observation of criminal activity that could be anything from robbery to who knows what. I'm sure you can find the info you're looking for somewhere, but I hope you decide to find more constructive uses for a laser... I'm probably not the only one who might wonder about your motives.
 
yes i would love to toast those speed cameras..... i think anything above 150mw ( green or red) would toast it nicley
 
A laser is a pretty stupid way to disable a GATSO though, why not just spray the lens with black spray paint?
A paintball gun would work well from a distance.

Ultimatley using a high power laser to burn out any camera is stupid because:
A)You can't be sure it's dead
B)It will probably see you moments before it gets burnt
C)You will get charged for having a dangerous weapon ontop of vandalism.

It'll see you moments before you spray it or shoot it too.Besides, a paintball marker would qualify more easily as a dangerous weapon than a 150mW laser and it would be hard as hell to hit with over a distance especially in wind conditions.

Yes but you will need to hit the CCD directly to do any major damage to it, and it might not be permanent.
Where as with paint you can visually see that the lens is blocked.
The incident angle is much more important with the laser so you are more likely to be seen directly (vs wide angle with a paint ball gun)
And I think you could be pretty damn accurate, considering that the divergence of a laser will equally limit you.
That and IMO 150mW is too low, the cameras round my school have a 'black' mirror type coating which would take huge powers to penatrate.
 
Again I already said I wasnt planning on building anything but several people jump to the conclusion that Im planning some kind of crime (guilty conscience much?).
This is a search for information on a subject that apparently many here are to closed minded to consider.

Your personal opinions on the matter are irrelevant chris and I will continue my research despite any negative things you have to say about it. So unless you are here to contribute in a positive manner please dont post.

Moving on.

Things to consider:

The range the laser has to perform the task from can range anywhere from 50-250 feet away.

The laser and power supply need to be self contained in a relativley small package thus large industrial laser are not suitable.
 
Really you are talking shit, if you care so much, go and buy a CCTV camera and test it yourself.

In reality, anyone intent on doing this would just buy a 500mW Scorpius and be done with it. If that doesn't work then you are going to struggle to find anything more powerfull in such a portable package.

You have never posted here before, and your first thread is about how to 'hypothetically' wipe out a CCTV camera? Yeah, that's just the publicity the laser scene needs.
 
Well Chris instead of being so arrogant why not just post:

" Hey a laser powerful enough to do the job is commercially available and its a scorpius 500mw "

I found out that the military has already designed a device to do exactly what I described. If you want to take issue with the development of such weapons because it gives the laser "scene" a bad name you can contact the US government and complain.

My first post should not go directly to the point ?

I was thinking the same, you'll just need a camera to see the beam.
 
Not to mention laser goggles, which would look somewhat suspicious ;D
