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.
Can't ever discuss these two without bringing up the Wagash ceremony.

Not yuuuuuge enough.
Linux, you magnificent bastard, I read the fucking manual!
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
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.

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.
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.
Bent, folded, spindled, and mutilated.
That is for prisons well the bomb is on them. But if you get on the work crew then you can go past the wall.
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.

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?
Let's not forget that India and Pakistan were one nation until the Partition driven by the British. I think it's fair to say that India is a little of everything and always has been.

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.

The sensor could be back at the laser location if there is a corner cube reflector at the far end.
