High Tech Borders for KSA

KSA is into building high tech borders, just like the USA and Israel. From HERE, hat tip to Armies of Liberation:

Now Saudi Arabia, like India, is building not one, but two separate border fences on different fronts. The first is on its southern border and is intended to try and get its illegal immigration of 400,000 people a year from neighboring Yemen under control. The second, far more ambitious one, is along the Saudi border with Iraq and is an attempt to prevent Islamist extremists in Iraq, both Sunni and Shiite, from exporting their violence and doctrines back into Saudi Arabia.

However, modern barriers are not just about orders for barbed wire and concrete: They are also about night-vision enhancers and sensors, and every kind of high-tech electronic gadgetry to detect explosives, weapons, drugs and whatever else terrorist organizations and drug gangs try to get across closely monitored borders.
