They claim the guide itself can be used as a defense against drone cameras because of its mirrored surface.
This thing is not for The Enemies of the United States (although obviously anyone can use it.) It's for all of us. In their own words:
Our ancestors could spot natural predators from far by their silhouettes. Are we equally aware of the predators in the present-day? Drones are remote-controlled planes that can be used for anything from surveillance and deadly force, to rescue operations and scientific research. Most drones are used today by military powers for remote-controlled surveillance and attack, and their numbers are growing. The Federal Aviation Administration (FAA) predicted in 2012 that within 20 years there could be as many as 30.000 drones flying over U.S. Soil alone. As robotic birds will become commonplace in the near future, we should be prepared to identify them. This survival guide is an attempt to familiarze ourselves and future generations, with a changing technological environment.
Discovered by Sobchak security, the guide also has extensive information on the other side, including "tactics for hiding from drones and interfering with the drones' sensors, collected from various online sources" and how to hack them:
Neat Drone Survival Guide will be a must-have for everyone very soon
