I just thought of something:
Imagine drones constantly running up and down the length of the fence, and there are recharging stations at the top of the fence every mile or so, enabling the drones to automatically land on them and recharge.
There could be 24 hour electric drone presence constantly running the length of the fence, constantly sending back video and even including software to recognize people and call their presence out to manned guard stations.
Imagine a large blimp at 10 thousand feet with radar, live video feed and thermal video....oh wait, we already have this... one blimp covers hundreds of square miles....so why does the border patrol not get this real time info..... because the military is not allowed to give this info to the border patrol.... classified and all....now imagine if Trump allowed this info to be passed on in real time....
Drones of varying types have already been used regularly for border enforcement. Big increases are underway, as part of CBP technology programs, and new Military support.
Fixed cameras, alarm systems and sensors are great for monitoring the fixed border line, while drones are also great for tracking intruders.
Beyond these existing types of remotely piloted aerial drones, new varieties of terrestrial patrol robots (semi-autonomous or autonomous) will also be able to deploy quickly, after the hard work of building good barrier and patrol road are is complete.
This wall is reported to be heavily endowed with tech.
It has sensors to detect tunnel work.
I believe it has sensors to let the Border Patrol know there is activity as a certain spot too.
I’ve read some reports on it, but haven’t seen enough reports of this type to nail it down for you.
You might be surprised what is in there. The drone idea may merely be a duplication of capability.
