Security Systems
A Primer

Disclaimer: We don’t advocate trying to get past a security barrier, simply because it’s there for a reason and chances are you’ll be breaking some law, minor or major. The worst case is you could get killed, so don’t try this. This document is in place for informational purposes only to advise on which types of fence and detection system can be breached and the level of security. But don’t expect to ever get past anything I design, maintain and upgrade, un-noticed, because you won’t.

 The President and CEO of Vortex Research Inc., has designed a number of security systems both physical (military bases, borders, key-point installations) and virtual (network/internet, encryption) as well as defensive/offensive weapons systems for military and paramilitary organization. These documents will deal only with defensive physical barrier systems, deterrents, differing forms of detection and the potential for circumvention. Topics to be covered are;
