Prison Reconnaissance Information System

Introduction

Remote-controlled drones have become utilized in all sectors of human operations, ranging from recreational use to law enforcement. Not lagging behind is the use of drones to smuggle contraband items such as weapons, mobile-phones, and drugs into security installations such as prisons. Reports show that in the UK, incidents of drones being used to smuggle contraband faced a jump from just 2 incidents in 2014, to 33 incidents in 2015 (“Drone Jail Smuggling Incidents Soar” 2016). British authorities estimate that almost €1.4 million worth of drugs alone has been smuggled into the prison. In nine prisons across the country, such deliveries were made. As a mid-range remote controlled quad-copter (the most commonly used type of drone) is cheap to purchase, can carry weights of 1.5-2 kg and can be flown without any prior experience.

 

With the P.R.I.S system, we seek to implement an acoustic analysis model to detect and localize drones. A database of the extensive acoustic drone sounds samples used to train and test the drone, is published here, for further open-source development and experimentation.
