For a prison, security is forefront in consideration, not just to keep people in, but also to keep people and contraband out. In low security areas, prisons can also be subject to armed attack in the attempt to free prisoners. In other areas, a more recent problem of criminals attempting to smuggle drugs and cellular phones in using Unmanned Aerial Vehicles (UAVs) has started to appear. Prisons can therefore benefit from systems that provide protection against ballistic and explosive attacks, as well as systems that prevent the use of unauthorized UAVs. In addition, for the primary task of keeping people confined, UAVs provide assistance with their ability to provide additional surveillance.
