NTDS Capability Scenarios

NTDS Description & Capability Scenarios



This system is still in concept and development phase. The scenarios and capabilities described below are for explanation purposes to help visualize the proposed system capabilities. Although technically feasible, TSSI has not completed these capabilities development and is dependent upon successful financial support for these efforts. 

The NTDS is a complex and comprehensive public safety security capability under  development that implements a three zone protection boundary scenario. The section below provides a brief definition of the three zone protection boundary. 

Zone 3 (Z-3) – Outer boundary and  provides top-level screening and identification prior to the inner zones; identifies large and overt threats; determines and detects restricted-area breaches (perimeter and access roadways etc.); identifies developing threat scenarios. Integrates with and augments existing infrastructure and implements aerial drone capability.

Zone 2 (Z-2) - An inner boundary which serves as a gateway (approach) corridor. Focus is detection and containment of both concealed/unconcealed threats (e.g. rifles, assault weapons, knives/machetes, handguns, explosives, flammables, and chemicals). Implements the Robotic “Bear Hugg” Sentries.

Zone 1 (Z-1) - The innermost zone, serves as an entry boundary into the sterile (protected) environment. It provides for the finest level of inspection and detects potentials weapons at the finest level of detail. Implements Mantrap Vestibule Inspection Que (MIQ) detection & containment.

Protected Environment (PE) – The sterile area created by the zone defense and implement positive ingress and egress for everyone and each access event (includes all staff, equipment transfer, construction work, all deliveries, and ramp or platform ingress and egress).

The system incorporates multiple sensor technologies, integrated methodologies and equipment to achieve a stand-off threat surveillance, detection, and mitigation or containment capability. The section below  provides a description of each NTDS subsystem, applicable security zone, and the prescribed equipment configuration for that zone.  Designed for use in a Public Safety context, the NTDS has application across a broad array of venues and most notably for gun free zone enforcement. 


NTDS Subsystems Descriptions


Electronically Scanned Sensor Array (ESSA) Detection Panels   (EDP)

The EDP comprises a suite of   sensor technologies that are configurable for specific zone threat detection applications. Currently there are 4 specific detection panel   sensor configurations designated for use in equipment applications for Zones 1, 2, and 3. They are:
 1. Detection Panels configuration   for MTA and MIQ
 2. Overhead Gantry Sensor   Configuration
 3. Street Pods Sensor Configuration

   4. Dispersed Sensor Configurations
  "Detection Panel configuration details are TSSI proprietary  information".


Detection Processor Controller Module (DPC)

The DPC is the brains of the system  and provides the information processing capability. There is a master DPC and subordinate DPC configurations associated with each subsystem capability.


Robotics Suite, Aerial Drone Capability, and Active Barriers

This suite comprises the following  robotic capabilities with applications in all three Zones:
 1. RBS (Ground maneuverable Robotic  "Bear Hugg" Sentry) which has a suite of sensors and capabilities that include threat apprehension and removal.
 2.  DBA (Dog Bite Apprehension Assist) sentry is an electro-mechanical robot configuration designed to scale up to seven (7) foot obstacles and manuever various terrains at travel speeds up to 18 mph. DBA has a suite of sensors,  livestreaming video, audio broadcasting, autonomous target tracking , navigation, and external collaboration.

 4. Active Bollards and Barricades   which are COTS equipment integrated into NTDS capabilities for physical   barrier threat mitigation.


Gateway Multi Tunnel Array (MTA)

The MTA comprises the Tunnel   technologies exclusively applicable to Zone 1 and provides the most intense and detailed threat detection capability. MTA has the following configurations:
 1. The Transition Entry Tunnel   (TEnT) which implements an array of sensors and equipment technologies. Applications include  high traffic high security facilities such as high security Federal Facilities, Immigration Border Crossing stations and etc. The MTA incorporates 3 Queues designated Entry, Staging, and Inspection.
 2. The Transition Exit Tunnel (TExT) implements both sensor and equipment technologies to ensure positive egress  capabilities.
 3. Mantrap Vestibule Inspection  Queue (MIQ) is the MTA standalone inspection queue technology which also incorporates threat detection and containment capabilities. Its exclusive Zone 1 application includes a broad array of public venues and commercial entities.   It is configurable in multiple clusters to accommodate traffic flow efficiency.


Surveillance Zones and associated Equipment Configurations


Zone 3

ADC Drone, Overhead Gantry, Active   Bollards and barricades, DPC module


Zone 2

ADC Drone, RBS, Overhead Gantry,   and Street Pods


Zone 1



PE - Protected Environment

MTA or MIQ and TExT are implemented in each Ingress and Egress access point for the sterile or protected environment concept.

The NTDS capabilities will include detection of a range of threats such as concealed weapons, explosives, and dangerous chemicals and toxins.  The system’s ability to detect and report the above range of threat provides valuable situational information for first responders and law enforcement.  Additionally,  with the use of the Robotic “Bear Hugg” Sentry (RBS)  for threat apprehension and the Aerial Surveillance and Tracking Drone Capability (ADC) for surveillance, tracking, and the live streaming of situational data, brings significant capability for prevention of undo scene exposure of first responders and law enforcement to dangers. A concept depiction of NTDS Robotic Suite (RBS and ADC) is provided in illustration at the beginning of this webpage.  This final section provides a description or example of the capability scenarios by Zone that are in various stages of design and development to realize the full potential of the NTDS public safety security concept.  

Capability Scenarios by Zone

Zone 3
  Normally pertains to outer boundaries of sensitive/high security facilities   such as Industrial Plants, Refineries, Airports, Powerplants, water treatment   facilities, etc.

Scenario 1 - Vehicle or Motorized Equipment is proceeding on access road to restricted access boundary road checkpoint.   The roadway Overhead Gantries conducts surveillance of all traffic prior to reaching checkpoint. License plate numbers, Vehicle VIN, required   placards, photos, and facial recognition data are captured (if driver/occupants are not masked) and confirmed instantaneously with SOC via digital datalink as standard routine for all traffic. Additionally, patrolling ADC drones (ADCs flying a pre-programmed autonomous flight orbit) capture and stream live video of all traffic.
 a. If vehicle is not authenticated   on all credentials the flashing roadway warning signage is initiated advising driver to stop immediately and pull to shoulder (instructional roadway signage warn drivers to stop immediately for flashing alert signage).   Authorized transits/access are briefed beforehand and must provide a cell phone for authentication purposes (Driver must text SOC prior to departure for the code word) .
 b. If vehicle does not stop, the   roadway barricades and shoulder bollards will be deployed.
 c. SOC takes control of an orbiting ADC drone and deploys to suspect vehicles or subjects of   interest.
 d. SOC support team is dispatched   with RBS for on-scene control and threat mitigation.
Scenario 2 - After hours Vehicle or pedestrian enters access roadway or   adjacent property accessible (Warning Signage posted). This activity is   picked up by overhead Gantry image sensors and 24/7 orbiting ADCs.
 a. Actions depicted in sections c   and d of Scenario 1 above applies.

Capability Status - In Progress


Zone 2  

Normally pertains to access corridors for public centers, sensitive/high security buildings. Include adjacent parking garages/lots, direct access walkways, access to public venues, and sports events. Other important venues are those designated Federal Gun Free School Zones (GFSZ).

Scenario 1 - Vehicle approaches entry to parking garage/lot and Overhead   Gantry and dispersed sensors integrated in ticket dispenser captures vehicle   credentials, occupants photos and facial recognition data which is processed   instantaneously for authentication. 

 a. If all data is authenticated, the  barrier rescinds and the vehicle is permitted entry. 

b. If all data is not authenticated the   vehicle is denied access and SOC system submits report to up-chain authorities   for required actions and reporting purposes.

Scenario 2 - Vehicle passes authentication and enters parking   garage/lot. (Parking lot is under surveillance via existing CCTV or NTDS overhead gantries and dispersed sensors) Occupants exit vehicle and an unconcealed assault weapon, knife, machete or firearm is captured by the surveillance system, The NTDS artificial intelligence and shape recognition  software alerts the SOC with scene information/data to dispatch area RBS for contact and containment of suspect/threat.

  a. If suspect detects tracking and runs, the RBS continues pursuit of suspects.

b. The SOC dispatches ADCs to assist suspect pursuit with aerial surveillance and tracking.

c. RBS maneuvers to suspects and effects the apprehension and removal of the suspect to a predetermine safe area for LEO processing.

d. The RBS provides safety for first responders and LEOs in this   scenario by providing a standoff apprehension capability.

Scenario 3 - Occupants exit vehicle and walks down direct access corridor when NTDS Street Pods combined with Overhead Gantry detects concealed assault weapon or machete or firearm using NTDS artificial intelligence and specialized sensor technologies and software algorithms to identify concealed weapons, explosives, and hazardous chemical.

a. SOC is alerted with scene data and RBS is dispatched to effect   apprehension and ADC dispatched for aerial surveillance and tracking   assistance.

b. Actions depicted in Scenario 2 sections c and d above applies. 

Capability Status -  In Progress


Zone 1
  Normally pertains to the Entry/Ingress threshold and Exit/Egress threshold associated with access to protected environments (PE) such as Gun-Free-School   Zones (GFSZ), designated Gun-Free-Zones (GFZ) that includes schools,   colleges, place of worship, Amtrak Trains and train stations, Subway systems   and public transportation, Airports, Office Buildings, federal Buildings,   Malls and shopping centers.

Scenario 1 - The NTDS Multi-Tunnel Array (MTA) and/or the subsystem   component Ingress Mantrap Vestibule Inspection Queue (MIQ) would be installed   in entry of facilities designated protected environment (PE). The Entry or Ingress installation of the MTA or MIQ will be in multiple cluster   configurations as required to accommodate traffic throughput. For enforcement of the NTDS positive Ingress and Egress control requirement, Transition Exit Tunnel (TExT) or Egress MIQ capabilities are implemented on all PE facility exit points. The TExT or Egress MIQ prevents entry from the facility exterior and   prevents attempts by anyone to avoid screening before entry. Dispersed sensors are configured in the area directly in front of the MTA and/or the   Ingress MIQ entry to capture all activity. The RBS (Bear Hugg Sentry) and ADC drone are stationed nearby for use as may be required. For any threat that is not detected in the Zone 2 area or if there is not an adequate Zone 2 space, the Zone 1 NTDS configuration implements all detection sensor capabilities. When a person enters the MTA or the Ingress MIQ accordion doors   closes and lock while screening is in progress. The entrant is immediately   scanned from head to toe for any weapons (bladed or pointed, firearms or   components thereof, hazardous chemicals and bio toxins, radiation emissions,   and explosives). This is done in a very short time literally seconds and this   include the information processing. Information processing is performed by   the Detection Processor Controller (DPC) executing the NTDS proprietary data   fusion software. The MTA and/or the Ingress MIQ incorporate a conveyor belt scanner   for processing backpacks, purses, and briefcases.

a. The SOC is alerted of any threat detections and they provide direct   communications and instructions to the detected MIQ occupant.

b. When a threat is detected, all adjacent MIQs are permitted to   complete existing in progress screening after which screening is suspended   and queued entrants are directed behind the security safety line to allow   processing of the detected threat.

c. The Ingress MIQ doubles as a security barrier while threat   extraction is executed. 

Scenario 2 -  If a person approaches   the MTA and/or MIQ entry area and does not enter and the dispersed sensors   detects a threat the on scene Zone 1 SOC duty support member will initiate   the RBS to effect apprehension and extraction of the threat to the   predetermined safe area.

 a. The on scene SOC support   team duty member will be certified in operating the RBS.
