Counter Camera detects binoculars, cameras and rifle scopes pointing at you and even people staring

Thanks, S! Also, don’t forget about laser distortion techniques: Heat distortion of laser (remember mirages?) and aerosol interference.

Remember, also, that detecting a lens doesn’t automatically mean ‘scope’. Detecting an eyeball doesn’t automatically mean ‘homo sapien’.

I want one. :’) Thanks hennie pennie.

Sounds like it shoots out faint light beams and looks for the reflection. So accommodate it with lots of reflectors to find, day or night.

If it shines green it isn’t a man or a dog....

[Windcatcher]

I wonder what you do to protect NV optics from it...

for those of you interested in one of these hex type filters, I used to be in photography you can buy what is called a grid spot at any used camera store or online.

You could probably outfit your whole set of scopes with just one grid probably a 10 degree type (there are 3, 10, 30 and 40 degree grids)

That would certainly booger them up. Shoot, just a long tube would do the trick as you won’t be pointing the scope at the detector, and it can’t detect what it can’t see.

[Still Thinking]

I always have haze filters on my scopes,would they make detection of the optics harder for this system?

It would help. If this is the same system I was reading about before, it's lenses that get it excited. Can't really have it going into whoop-whoop mode every time it detects a window, can we? So in your case, its beam would have to pass through the filter, hit the lens, and pass BACK through the filter on the return trip. Each of those passes will diminish the signal strength. Whether it will diminish it below the recognition threshold for lenses, who knows?

[Still Thinking]

I recall reading many years ago (probably the Carter era) that the Soviets had such a device, and it would automatically fire a laser into the scope, binoculars or eyes. Permanently blinding any one foolish enough to even look upon them.

Cool! Now to figure out a way to get a lens between the thing and someone you don't like.

[Still Thinking]

If someone is a couple of hundred yards away scanning the area with this device where would you put the claymore? And since it is an optical device what would trip the tripwire?

He's saying the lens, once detected, will draw people to the location where it was seen.

I’m reminded of the introduction/demo of some grand new anti-sniper technology before an important crowd. One guy borrowed someone’s umbrella, wandered off, and within 15 minutes popped up from the grass right in front of the wondergizmo.

Everything can be defeated.

[gundog]

Flaw with this is when it lights up a scope the scope may be there to be lit up.

Yup. I want one for deer season.

[hiredhand]

I can’t see how this could possibly work against something like an ARD, especially if it’s at such an angle that it doesn’t actually “see” glass.

[PIF]

Since the device can detect eyeballs staring, be sure to close your eyes before using... :)

[DuncanWaring]

Lenses are cheap. A sniper could salt an area with hundreds of them.

Marbles are even cheaper.

Anything convex and reflective would probably work.

[Thane_Banquo]

Wow, I won’t even be able to look at women’s breasts.

This is an utter and complete usurpation of the rights of MAN: Life, liberty, and the pursuit of ogling. I am OUTRAGED! OUTRAGED!

Actually this isn’t new at all. Ever see a surveyor on side of the road? That instrument the surveyor uses is the exact same technology except it only gives bearing and distance. The rod the other guy holds is a multi facet prism mirror, it doesn’t have to be pointed directly at the instrument. That instrument is called a total station, it fires a laser toward the rods prism and bounces back information it collects. But as was said a killflash and other deterrent will easily defeat it, with killflash the scope could only be detected if it was pointed directly at the device.

Different optics. The multi-cube-corner mirror is designed to reflect any beam back at its source. Imagine if the intended use of the mirror were very directional, you could put an opaque tube on the front of it pointing in the desired direction. It would still serve the intended purpose but anyone off axis by a very small amount can't see the reflector. That's essentially what the killflash is, is a bunch of tiny tubes pointing on axis. No one off axis can see the lens (and thus a flash from the lens, and even on axis, the shine is broken up by the grid pattern.

If this device is emitting lasers in all directions, why wouldn’t an enemy launch a missile designed to hone in on something emitting lasers?
