Thieves and robbery. The new rules change the game. Moving to the city and living among thousands and thousands of people increased theft. The easiest and most logical thing was to build higher and thicker walls to keep the bad people outside. Thanks to modern technology, for the first time in the human history, we might go back to the roots where it all started. Just think about the psychology of it. In a 120 person tribe when somebody stole something it was easy. They killed him on the spot. Or they send him to the jungle to live with the beast. They know the consequences. Punishing just one thief solved the social problem for generations.
Murder. We can play this cards again. Not murder … but fear of getting caught. When they know they will be caught 100% they won’t even try. Placing lots and lots of Arduino or raspberry sensors (1…5$ each) would sense almost anything. (hyperlink Arduino, security). I’m not going to get into speaking about it here, that would be tens of pages about the sensors. This technology is not like your or your friends motion sensors. Those are worthless in comparison. I speak about hundreds and hundreds of various types of sensors. The main idea is that we don’t need the “fortress” and “brick walls” anymore. The war is played in cyber space not with Stone Age ideas and tools.
That era ended. The “consequence” can be showed easily. If somebody just looks at your property a really loud voice can explain them that they are facing x years of jail time. If they move another 10 centimeters than the system can call the security company. It can put the conversation on “loud speaker”. Laser beams pointing at the thieves while they move … extremely powerful flashing lights are quite intimidating. Disturbingly loud noises that are so loud they can’t hear each other. Just think about the pain involved. Spraying water on them and “speaking “about some high voltage under the lawn … This will scare them away.
Cherry on the pie. A few high voltage (Tesla style) lightning’s would be the cherry on the pie. You can project near them a visual documentary with explicit content about how people are raped by other people in the prison … and how often. The jail time they serve for robbery. The video can “fallow” them while they move. The time could be shown…how much time will take the cops and the security company to get here with or without traffic. Fair enough. Those who have technology to pass this cutting edge system won’t show up at your doorsteps. They will be at the British museum or in an art gallery in downtown New York. The question is not if they can pass the “walls”. The question who can do it? And will he do it? As an additional idea: you can watch various patterns. If a pattern breaks an alarm is silently deployed. Read about the smart hedge.
