Did you read the article? They cut through unfinished sections of wall.

When complete and hooked up to all the sensors, Border Patrol knows the instant they start cutting and is ready before they even get through.

Lots of 100 dollar battery powered grinders can cut through in tests for nearly a year :

It should be two fences, always, and a shoot to kill between the two.

So a DMZ .... I say 3 miles into Mexico leading up to the USA is a shoot to kill. Use drones to kill them.

If Mexico bitches we bomb them back into the stone age.

Nothing that 220 volts can't cure.

Yes, and? That eats up time, and Border Patrol knows the instant you start cutting because if the sensors installed. They're waiting for you by the time you get through.

Here's video of the double wall at Otay Mesa.

Some of the damage

Not all. Some. They also have used (surprise) ladders.

I’m interested in the sensors they intend to use. Allegedly they will sense the vibration and allow CBP to react. I’ve dealt with industrial control quite a bit. To put it mildly, if it’s wired, there is little way the sensor system will not be very simply disabled with cheap, readily available parts. The talk of sensors and response, in my opinion, is essentially a whisper campaign intended to act as a deterrent. It will keep some people from trying, but will not be effective against the cartels.

You could rig up a vibration sensor inside the wall and it'd detect vibration for a long way in either direction. All you need is that moment of detection and the Border Patrol Predator drones can already be directed to the location. Any disabling of the detector after the fact is useless.

What kind of sensors detect that? Movement ones near the wall or ones that actually tell if the wall is being tampered with? I need that shit for my house.

Not going to give you specifics, but there's a cable at the base of the concrete foundation attached to the metal and the metal rod within the concrete within the concrete filled beam going all the way up.

It detects vibrations below [digging] a certain double figure feet depth and will detect heavy machinery driving on the border road or actual attempts at trying to tamper with the barrier such as vehicles trying to push against the barrier or try to cut or drill through the steel or concrete with power tools. New sections require time to be connected to the command centers. New section of walls are often hollow and they get the concrete filler within the beam poured in later.

It's metal. Any vibration will travel extremely well.

Hell, you could put your ear to the metal and hear from a mile away. A sawzall is loud, that metal will transmit the vibrations for a long distance.

I used to install strain gauges on valve stems that could detect a twist from my hands..

Smaller than a postage stamp size device..

This is correct.
