S4 Worldwide’s Sentry Drone, Detect and Defeat System

S4W's Sentry Drone Detect & Defeat (D³) platform is designed as an unauthorized drone identification security system that also delivers real-time alerts and digital evidence collection. The size, speed and varying shape of drones make identification extremely difficult for a single monitoring method.

The D³ platform integrates an enterprise-grade multi-sensor warning network with acoustic (audio and ultrasonic), optical (video and near infrared), and WIFI (WLAN) detection technology to identify drones, in real time, that pose a threat to critical infrastructure, prisons, executive protection, government facilities, sporting events, airports, and personal home protection.

The D³ platform can be mounted permanently to facades or special poles in order to survey a defined section of the sky 24/7. Small Unmanned Aircraft Systems (sUAS) have a range of access and agility that sets them apart from other types of security threats.

Because of their growing popularity and inconspicuous design, detection is critical to maintaining the highest standard of security. It is the first step in guarding against unauthorized drones:

• The D³ platform deals with challenges from smugglers using drones to deliver drugs, weapons, cell phones and other contraband onto prison facility grounds.

• The D³ platform easily integrates into zone-based alarm and camera systems to achieve consistent and complete monitoring of perimeters, airspace and centralized facilities.

• The D³ platform delivers real-time advanced alerts to quickly counteract threats, while contributing to more comprehensive surveillance through monitoring of air space and ground perimeters.

• The D³ platform supplements and integrates with existing security systems for swift law enforcement response and preserves data from alerts for use as digital evidence in legal proceedings.

Allow the D³ platform to be your preemptive approach to eliminating unwanted problems before they have a chance of causing real harm.

Drones – the New Security Threat

Unmanned Aerial Systems (Drones) pose a legitimate threat in the U.S. In spite of being relatively new technology, drones of varying types and sizes are readily available for consumer purchase. 

These devices are not only becoming cheaper and easier to own, but technology has advanced to such a point that virtually anyone — hobbyist or terrorist — can fly one…it takes nothing more than a laptop or tablet with a joystick to fly one.

Even those amateur pilots with good intentions can pose a safety threat to the general public, government agencies, sporting events, airports, etc. There are a multitude of aspects associated with public safety that is of concern. Consider some of these security threats:

• Drones can be shut down midflight, injuring bystanders and causing property damage, or flown into situations like traffic jams, buildings or people.

• Drones can be flown into sports venues packed with spectators.

• Drones can be flown into commercial jets or jet engines while in flight. Interestingly enough, this scenario has played out several times in the past few months at several airports.

• Terrorist organizations could easily design and build a drone capable of carrying several pounds of explosives into public areas and government buildings.
• Terrorist organizations and extremists could handle, with a high degree of anonymity, explosive or incendiary payloads, radioactive materials, chemical agents or biological agents.

• Any individual with a teaspoon of technical know-how could use drones to stalk, harass or eavesdrop on another individual.

• Smuggling: There have been multiple cases where drones have been used to smuggle illicit material, usually across borders or into prisons. In November 2013, a drone was potted flying over the walls of a prison in Quebec, and in March 2014, a similar event occurred in Australia. Earlier this year, a drone carrying drugs was discovered crashed just south of the U.S.-Mexico border.

• An attacker could use a drone to spray a weaponized chemical or biological agent over, for example, a crowd of people or in a downtown area. In 2003, then-Secretary of State Colin Powell warned that Iraq was planning on using drones to deliver chemical weapons.

• Terrorist Attack: In this instance, an attacker might strap guns or explosives to a drone and fly it into people or structures to inflict physical damage or loss of life. The targets of these attacks may be individuals, buildings, or transportation infrastructure such as commercial airliners. An Oct 2016 report by the New York times documents instances of ISIS using Drones for explosive attacks on Iraqi Troops while the Pentagon expresses concerns over potential threats to the United States using this same capability.
