Counter-surveillance is both art and science. But regardless of what you are trying to do to protect yourself, there are certain rules that has to be followed. First, you need the RIGHT TOOL FOR THE RIGHT JOB. Every counter-surveillance item is specialized for a specific purpose. What works well to find a camera is not necessarily good to find a hidden microphone. Second, you would have to consider the resources of who you think might be after you. If it's someone with the same financial and legal resources as the average joe on the street, then BASIC to INTERMEDIATE counter-surveillance items are required. If it's someone with better than normal resources, advanced electronic skills (the ability to make his/her OWN electronics), or Law-Enforcment resource access (or Mob-level resource access), the INTERMEDIATE TO ADVANCED counter-surveillance items are required. If it's actual companies, Law Enforcement forces and Government resources, then ADVANCED TO ELITE level countre-surveillance items are required. Consider your opponent, and your own resources, when you proceed. If you have any questions, please feel free to contact us on what types of items you might need.
