India Installs 'Laser Walls' At Border With Pakistan (nbcnews.com)
schwit1 writes: After experimenting with barbed wire, surveillance cameras and even cowbells and camels, India has now reportedly introduced "laser walls" at its border with archenemy Pakistan. Both New Delhi and Islamabad deploy more than half of their 1 million and 600,000-strong armies, respectively, on the border. India is setting up the laser walls to "plug the porous riverine and treacherous terrain and keep an effective vigil against intruders and terrorists" in Punjab state, the state-run Press Trust of India reported. According to the PTI report, around 45 laser walls will be installed in Punjab state. Lasers beamed over rivers and hills will set off an alarm and alert the Indian Border Security Force if someone attempts to pass by, it added.
Can't invading armies simply go over, or more likely, under the laser beam? Dig a trench and drive on through, the beam is a straight line, but the terrain isn't.
I've abandoned my search for truth; now I'm just looking for some useful delusions.
we need one of these for merica
Can't ever discuss these two without bringing up the Wagash ceremony.

I figure someone will simply macgyver it using mirrors to bypass mirrors or just well polished steel and basically just make themselves a hole through the fence. I'd also wonder what happens if the reflective part of a potatoe chip bag went through. Would it set off false positives.
It's a detection system
I think Donald Trump should hire a bunch of H-1B workers from India to implement this along the southern border.
Get back with me when we have the head-popping Running Man virtual wall...
India should make Pakistan pay for the laser wall.
now if they manage to put those lasers on sharks... it's gonna be awesome.... but maybe they don't have the budget for sharks :p
Never antropomorphize computers, they do not like that
to put these "walls" in place. Same thing happened when the US put up "The Fence". It's a pork project combined with a bone to throw at your countries far right. A win-win really.

Trump here. This is my idea actually. The Mexicans were being stingy, so I can't build the wall out of what I wanted originally, which was concrete and lasers. Now, it is going to be just lasers. It is going to be huge, as long as the stupids in Washington don't get in the way. If the poor idiots in India can build a laser wall, so can America. But only if we want to be great again. So vote for America. Vote for Trump! #makeamericagreatagainyouidiots
You are all Indian laser walls. Beep! Beeeeeep goes the Indian laser wall every Pakistan releases sacred cows at the border. Beep!
If sufficiently well designed, this laser tripwire system might make just casually strolling across the border harder; but the opportunity for throwing false positives into the system just seems too easy and too vast to be dealt with.
If you don't mind losing plausible deniability, basically any opaque object you can lob from a safe distance will do the job. Have India send out a search squad every time you toss a paper airplane their way? Sounds like an economic win to me. If you want plausible deniability, see what you can do to encourage the local wildlife to wander around in the border area. Put out some food for stray dogs, subsidize some local mud farmers to graze sheep, whatever. Is New Delhi going to summon your ambassador for a scolding every time some mutt trips the fence?
There are various clever schemes for making it much harder to avoid detection when passing through a laser tripwire; but how much does that help you if generating false positives is so easy and cheap that it is trivial to drown out genuine positives?

That would have worked, except they needed... ...More cowbells!
Thanks, I'll be here all week.
Even if only because my enemy is your enemy.
VOTE TRUMP 2016
Let's BUILD THOSE WALLS and make THEM pay for it!
I'm rather amused by the prevailing nonchalant attitude to this laser wall, when it's not conceptually dissimilar to Trump's proposed Mexican border wall, except of course, for the higher-tech implementation of the Indian border wall. Of course, I'm ignoring concerns as to cost - or who's going to bear that cost. But what this wall does is not that much different from what Trump's wall will do, which is to divide the citizens of both countries and encourage parochial tendencies among their populations.
The winner is ... Pigs!!! Nothing but enormous pissed-off hungry tuskers for miles. The likelihood of not just touching pork but being eaten and *becoming* pork would be a powerful disincentive.
For anyone who gets past the boar zone, just have a few sows as backup, one per kilometer should be plenty.

If you want to make the whole system irrelevant you don't need to dig or circumvent it. You trigger it. Over and over and over again, at the most remote places you can find. Get a tennis ball thrower and a hopper that can hold a gazillion balls, park it on Pakistan's side they aim it right at a beam. Have it set to shoot a ball every random interval between 1 and 40 hours. With a dozen of those bad boys, the whole system would be useless.
Nobody's made a Command & Conquer NOD laser fence reference yet?
Can't ever discuss these two without bringing up the Wagash ceremony.
It's spelt Wagah by the way, not Wagash, you managed to misspell it twice.

Look at all the stupid comments on here - do none of you know WHY India wants to keep Pakistanis out?

Millions of people killed because, as always, muslims can't get on with anybody who refuses to join their insane death cult.
A quick blow of face powder or even a vape cloud followed by a rapidly planned series of handstands and cartwheels will easily allow you safe passage. What were they thinking?
Right on. Pakistan is a 100â... Islamocracy with associated death_cultism....while ... India is historically a Hindu country with a secular Constitution outlook and way of life.
This will greatly help out the show Coma-Doof Warrior (the Mad Max guitar guy) puts on there. He already had trucks and flamethrowers. All he was missing was lasers.
this is doomed to fail. people make up a nation-state, and membership is as arbitrary as geographic borders.
Remember kids, if you're not paying for the service, YOU ARE THE PRODUCT THAT IS BEING SOLD.
As long as we're already descending into aburdities, here's how to beat the laser wall:
Each vehicle crosses in less than 1/2 of each signal pulse width, so the receiver never misses a bit.
Pakistan can reward me with bitcoins or local produce for that hint.

As laser beams get triggered by just about anything moving through them, ie, birds, land animals, falling debris (my favourite one), and fallen leaves/twigs. Those soldiers are going to have one heck of a time filled with non-stop activity slowly grinding them to the point of dullness and ineptitude.
The sensor could be back at the laser location if there is a corner cube reflector at the far end.
