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.

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
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
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
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.
