Sentinel™

Sentinel™ is the “software backbone” of ARA’s integrated security command and control system. The secure and completely scalable system is custom tailored to meet customer’s highest security threats and compensate for surveillance blind spots. Sentinel creates a head-end network to manage alerts and data from fixed sensors, cameras, ground radars, automated entry control and pre-set alarm zones to provide an enterprise solution. The system is also capable of managing mobile detection and assessment assets such as the RAPID® system, Pathfinder unattended ground sensors and UAS “fly-to-cue” surveillance.  

Sentinel is Security Equipment Integration Working Group (SEIWG) ICD 101 compliant, meeting the DOD communications protocol standard. Defense-in-depth is provided through successive detection, assessment and interrogation modules that provide all-weather, all-environment, layered approach to security that begins outside the physical perimeter, identifying potential threats as far away from resources as possible. This provides a space buffer to give security forces time to react to prevent theft or damage to protected assets. Sentinel automatically manages the surveillance assets and provides alarm indications to ease cognitive burden and boredom on 24/7 security monitoring personnel,

Sentinel’s “Capability Modules” range from wide area intrusion detection of potential ground, water and airborne (UAS) threats, to perimeter security around a single or groups of assets, to monitoring/protection of individual doors and rooms (witness/interview and intoxilizer) from an unlimited number of sensors. Sentinel integrates automated entry and access control to include license plate reading, reverse entry protection, vehicle and facial recognition, as well as Radiation-Nuclear detection and automatic tracking. All these add-on capability modules can be seamlessly integrated into the Sentinel system to incrementally improve or expand security capabilities in response to mission change or increased threats.

EO/IR cameras with on-board analytics provide accurate immediate visual assessment with digital storage of all camera feeds. Sentinel also manages video motion detection enabled cameras systems. The system allows for replay and export of video from all system cameras to provide critical information to for investigations, training and evidence to support prosecution of offenses. 

Notable Sentinel™ Technologies

  • Integrates COTS hardware (improved technology and reduced cost)
  • Integrates many legacy sensors (radar, camera, BMS, motion, etc.)
  • Real-time control of detection systems
  • Identifies sensor locations
  • Ability to temporarily mask alarm zones for maintenance operations or other reasons

  • Internet or Closed Network (VLAN) Sentinel™ configurations
  • Automatic alarm and event history with scalable duration based on operator’s requirements
  • User defined system editing permission levels allow operator customization of user interface yet ensure system integrity

Why It Works

Sentinel provides the capability to integrate a wide variety of sensors into a single management display to provide a complete base defense system. It provides defense in depth starting at wide area intrusion detection and visual assessment of ground, littoral and tactical small unmanned air system (sUAS) to identify a possible threat as far away from the protected assets as possible. The Command and Control Display Equipment (CCDE) user interface accurately displays all sensor locations, ground-based radar detection radii and assessment camera angles on a geo-rectified map also pinpointing the exact location and direction of travel of acquired targets. This provides space to allow defense forces time to determine the intent of the intrusion and dispatch forces to the right intercept location to prevent access to protected resources. Sentinel’s layered defense includes progressively smaller yet distinct user defined detection zones as distance to protected assets decreases. Multiple sensor phenomenology can be applied based on detection requirements (radar, fiber, motion, unattended ground sensors, etc.). Sentinel also integrates CCTV to include audio for monitoring base/facility perimeters, entry access portals, gates, internal circulation, armory/guardmount areas, interview and breathalyzer rooms, etc.
