Error in the text: 1000mW laser with 532nm wavelength which is green light.
1000nm light is infrared.

Just remember that lasers literally point back at you. So if you are recorded by any other camera they will see exactly who or what vehicle did this. If it’s a strong enough laser it’s likely a visible beam too so in a crowd it will be extremely obvious who is pointing it.
So back in the day the way you’d burn out a security camera was to swap out the diode in a pointer with a CD/dvd burner laser. They’re practically invisible and can pop baloons or start fires from about 50ft. Then the real trick is to get underneath the camera, you can reach just into the field of view and the lens will make sure enough of it gets to the camera to damage it. To an uninformed observer it just looks like you’re trying to light a smoke or tie a shoe or check a text.
Things have changed since then, but I can’t imagine that much.
Soooo…. A laser on a stick then?
I am pretty sure that at that wattage it would not be able to significantly destroy them, you could burn out pixels in the camera but unless you want to stand there for 10+ minutes shining it on the lens I don’t think you’re going to significantly hamper the vision system.
It needs to be more powerful than a class 4 consumer grade device.
Not that you can’t do it, but if you want to do it more effectively I am pretty sure something stronger would be required than a 1 watt device, Ideally you would want something that can just melt the photoreceptor entirely.
To further your efficacy you might want to use something in a wavelength range that is invisible to most cameras since any footage prior to melting is probably still saved somewhere and available to police. No visible beam means it’s significantly harder to pin it on you.Be warned however lasers in that intensity are very dangerous to eyesight and even incidental beam reflections off surfaces can cause damage to eyesight almost immediately, compounding that by making it a wavelength invisible to cameras you are also making it invisible to human eyes making it even easier to accidentally blind yourself without the right eye protection. Though it would be more difficult to aim if you can’t see it (there are ways around this as well such as buying a small camera that can see that wavelength and hooking it up to a video feed you use to aim it, potentially an in glasses screen (these are becoming much cheaper and readily available these days) as now you can order glasses to protect from that wavelength and put the lenses over your screen glasses and see exactly where you are pointing it without any risk of eye damage and very minimal risk of being caught.
At this point a water balloon full of paint seems cheaper, more efficient, and more discreet.
I wouldn’t say more discreet or efficient, but cheaper yes, at least in the short run but there will always be systems that are hard to hit with a balloon due to their height and if all they need is some solvent in a backpack sprayer to undo your work then in the long run you’ll need to buy a lot of paint and balloons. Efficient to me is carrying something that fits in a backpack and can be charged on a home outlet and take out hundreds
It does have a much lower upfront cost though which is a consideration
I mean standing point a laser at a camera for several minutes seems less discrete and efficient.
You can disable a camera in a few seconds. Pick the right paint with the right additives you may even damage the components.
Either way it’s a big cost to take it down and fix. I doubt they’re sending someone up on a ladder, but who knows. With the paint method someone could disable dozens in an hour.
You got me on the height though. Can’t best the laser there
You know all the posts about lasers… but has anyone just tried an adequately sized rock?
Hey, have we just tried telling methheads and crackies there’s copper in there?
It’s concerning that I’m not sure if this is real or not.
It’s on his truthsocial thingy, but that doesn’t have to mean it’s “real”
Its real
Yeah, the down side is you need to be in the camera’s field of view to do this, outing themselves.
And don’t point a 1000W laser at cops using Flock cameras, as it would definitely annoy them.
A 1kW laser would definitely annoy anyone nearby
Especially don’t do it while within the camera’s field and range of view.
