In 2023, German correctional authorities recorded over 200 confirmed drone incidents at prisons and detention centres. The number has grown every year since 2018. The pattern is consistent: drones are used to deliver contraband- mobile phones, drugs, SIM cards, sometimes weapons-directly into prison yards, bypassing perimeter controls that were designed for a world without consumer UAS. The operational disruption is significant; the security implications are serious; and the problem is structural, not incidental. Drones have become a tool of choice for organised criminal networks operating outside prison walls.
The Specific Drone Risk in Correctional Environments
Correctional facilities present a distinctive threat profile. Unlike airports or power grids, the drone threat here is not primarily about sabotage or espionage- it is about supply. The high walls and controlled entry points that define a prison's physical security create exactly the conditions that make drone delivery attractive: a captive customer base, a controlled space that is hard to search comprehensively, and a delivery method that bypasses every conventional control point.
Detection is the critical gap. Many facilities have no capability to identify that a drone has approached the perimeter until contraband has already been found. By then the delivery has succeeded, the pilot is long gone, and the investigation starts from zero. Early detection, before the drone reaches the wall, changes that entirely. It creates a response window, preserves evidence, and shifts the operational balance back toward the facility.
Detection before the wall is crossed is worth more than any reactive measure taken after. The window is short- seconds, not minutes.
DIDIT in the Correctional Facility Context
DIDIT provides the early-warning layer that correctional security teams currently lack. RF sensors placed around the facility perimeter can detect and localise a drone as soon as it powers up its control link, often while the pilot is still outside visual range of the walls. Direction-finding data is handed off to PTZ cameras for visual tracking and identification. The Operations Console alerts duty officers in real time, with enough lead time to scramble a response and where legally authorised, coordinate with police for pilot interception.
