Are you sure they wouldn't just light up your yard really well? I wouldn't mess with it unless you have night vision and want to see better than someone outside.

 

I think that the better strategy is for you to buy night vision goggles, wire your property with sensor alarms, and then when an alarm is tripped you grab your goggles and other gear, head to your predetermined vantage point, and then flip the switch for your floodlights which bath the property in light. Then take a bead on your intruders and when they take off their night vision goggles you fire off your laser pointer into their eyes and you blind them.

Your goal of blinding night vision goggles has to overcome the automatic brightness control circuitry built into goggles which automatically dims or shuts down the goggles when they are exposed to bright light.

 

Buy a few of those flash's used in discos. They flash at random intervals and will casue issues witht the night vison devices.

 

night vision

Bobbb, the problem I see is my whole property would have to be fenced in otherwise the deer, racoons, and other wildlife would be setting off the alarms and causing many sleepless nights. Also the laser would have to be extremely powerful to cause retina damage otherwise the intruder or intruders would only be temporally blinded.

These are the cameras I have been setting up on the property, they have night vision and the picture quality would be enhanced with an external source of infrared light.

I have Gen 3 PVS14s and the EBC is rated in milliseconds. The unit usually adjusts before bloom occurs let alone blinding whiteout. As for the Ebay product linked. The output on that is lower than the Manta Strobes we use for IFF. Bottom line is, preventing your position from bring observed using IR NODs is very difficult and requires hardware that would be very difficult for you to acquire.

On a serious note, I understand what you're aiming for - you want to deprive the marauders invading your property of some tactical advantage that they have in the form of night vision goggles. I don't think that IR lights are going to work because, as I noted earlier, the circuitry of the goggles is responsive to electromagnetic spectrum spiking. All that will happen is the folks with the goggles are going to see all of these point sources of IR sprinkled about your property and wonder why you bothered turning them on when they arrived. The capabilities of the marauders shouldn't be impeded by you having these lights.

Off the top of my head I think that a way to deprive them of their advantage is to swamp them with information - meaning that your body heat gets lost in a whole bunch of other heat sources.

Bob this is not technically correct. NVG's are only light enhancing, they have no capability to see heat or heat sources unless they are emitting some form of light. IR leds are used to illuminate an area for the goggles. I think the best someone could hope to "blind" nvg's with are some form of standard floodlight on your house or property but this would also pinpoint the light location and give aiming references.

Some of the sighting systems that do use IR are not impossible to defeat but the idea of trying to "blind" one is also again almost impossible.

 

IR is used on AN-PVS-7C night vision goggles to assist in illumination during low light conditions. Using IR will assist night vision devices not prevent the use of them! going against night vision devices is difficult to defeat, the best way is to have your own making the tactical advantage equal!

I'm not prepared to die on this hill because I'm not exactly sure how much new high technology has been incorporated into goggles (likely because of power consumption issues), but . . .

Active infrared night vision combines infrared illumination of spectral range 700-1,000 nm (just below the visible spectrum of the human eye) with CCD cameras sensitive to this light. The resulting scene, which is apparently dark to a human observer, appears as a monochrome image on a normal display device.[6]

Because active infrared night vision systems can incorporate illuminators that produce high levels of infrared light, the resulting images are typically higher resolution than other night vision technologies.[7][8] Active infrared night vision is now commonly found in commercial, residential and government security applications, where it enables effective night time imaging under low light conditions. However, since active infrared light can be detected by night vision goggles, there can be a risk of giving away position in tactical military operations.​

 

A 30,000 candlepower spotlight directed at an NVG will either fry the NVG or blind the user several hours.
I suggest magnesium flares.

 

I'm with Magus on this.
My NV scopes are sensitive to normal sunlight but not to IR light. In fact, such IR lights will only serve to illuminate the area in question better.
Driving lights (clear lenses vs. the amber lenses on fog lights) are a convenient way to brighten up areas and are 12V. Any such lighting source should be placed a bit away from where you'll be. I'll also point out that the range on the cheaper NV gear is ~100 yards.

 

night vision

Well if placement of IR LEDs around the property wouldn't blind intruders wearing night vision goggles, perhaps at best the LEDs would confuse the person. If you were to go onto someone's else property at night with night vision goggles and see all of these pinpoints of lights, wouldn't you wonder if it is an other person looking back at you with night vision or possibly some high tech intrusion alarm. http://www.ebay.com/itm/36-LED-Secu...asc=177&meid=8172804792645758691&pid=100009&prg=1088&rk=5&sd=281010623131&#shId

You could be right zimmy, but like idea of the racking of a shotgun slide scaring a criminal away it is not something I want to rely on.

I had the pleasure of working around a few criminals. In my experience thinking about long term consequences is not their long suit. They may well think about how lighting up your area helps them without considering the benefit to you.

Instead of confusing the person, you're likely going to improve the clarity of what they're seeing.

What I think you're going for is the bleaching out effect, kind of like what Spielberg did in the beginning of Close Encounters - a white light blinds everyone but as the aperture of the camera closes the details of the scene begin to emerge.

These IR lights are nowhere close to powerful enough to swamp the mechanisms in NV goggles. What Magus suggests is what will get you what you seek.

Here's the strategy which follows - the marauders have night vision goggles and you have welding glasses. To put them at a disadvantage and give you the upper hand, you should still be able to see through your welding glasses whereas they are blind, both with NV goggles and with their own eyes.

If you were to go onto someone's else property at night with night vision goggles and see all of these pinpoints of lights, wouldn't you wonder if it is an other person looking back at you with night vision or possibly some high tech intrusion alarm.

I don't think that these lights are going to be like cat's eyes glowing back at you. They'll be like lightbulbs, illuminating their immediate area with IR spectrum light, thus brightening up the area and taxing the NV goggles less in terms of being able to discern details. That picture above shows what IR spectrum light does to image quality.

 

Anybody remember Kurt Saxxon's eye popper gizmo?
that would blind someone without NVGs!one of those superbright
area floods modded with a strobe would play hell with them!
