  • P25 CAP Supplier's Declaration of Compliance and Summary Test Report Requirements for Subscriber Units

    P25 subscriber vendors must submit SDOCs and STRs to P25 CAP in order for the vendor’s P25 equipment to be posted on the P25 CAP Approved (Grant-Eligible) Equipment webpage.

  • Self-contained Breathing Apparatuses (SCBAs) Lessons Learned Report

    The Science and Technology Directorate’s National Urban Security Technology Laboratory (NUSTL) partnered with the Fire Department of the City of New York (FDNY) to conduct a comprehensive evaluation of open-circuit self-contained breathing apparatuses (SCBAs), a life-saving piece of personal protective equipment and a substantial financial investment for fire departments nationwide. Recent technological advancements in SCBAs promise to enhance safety, communication, situational awareness, and the overall mission effectiveness of fire response teams. NUSTL’s evaluation involved rigorous testing of SCBAs available in the current marketplace to analyze their capabilities, including new electronic safety features that facilitate information transmission between SCBAs and incident command.

  • C-THRU Operational Field Assessment Report

    The U.S. Department of Homeland Security's Science and Technology Directorate works closely with the nation’s emergency response community to identify and prioritize mission capability gaps, and to facilitate the rapid development of critical solutions to address responders’ everyday technology needs. As these new technologies near completion, the National Urban Security Technology Laboratory (NUSTL) conducts an operational field assessment (OFA) to evaluate the prototype's capabilities and operational suitability. This report documents the results of an OFA of C-THRU, a real-time visualization system intended to provide firefighters with technology that can minimize the disorientation associated with emergency response. It offers a suite of imaging, navigation, and visual communication applications via the helmet-mounted C-THRU Navigator and corresponding Visual Command platform.

  • P25 CAP Baseline Laboratory Requirements

    This Compliance Assessment Bulletin identifies accreditation and recognition requirements for becoming a DHS-recognized laboratory for P25 CAP testing.

  • P25 CAP Laboratory Equipment Requirements

    This Compliance Assessment Bulletin identifies several basic personnel, facility and test tool requirements for becoming a DHS-recognized laboratory for P25 CAP testing.

  • P25 CAP Accreditation Body Authorization Conditions and Criteria Agreement

    This Compliance Assessment Bulletin identifies conditions and criteria for DHS authorization of accreditation bodies to provide accreditation to P25 CAP laboratories.

  • P25 CAP Minimum Feature Requirements

    This Compliance Assessment Bulletin defines the minimum interoperability features and capabilities that are required for P25 subscriber and repeater equipment that are capable of conventional operation to be eligible to be considered P25 CAP compliant.

  • P25 Compliance Assessment Program Encryption Requirements

    This Compliance Assessment Bulletin addresses DHS taking action to stop the practice of manufacturers provided subscriber units with a non-P25 standard encryption without also including P25 standard AES 256 encryption. DHS also asks that manufacturers provide a path for public safety users to add AES 256 to fielded P25 subscriber units that are only equipped with non-P25 standard encryption.

  • CSAC FY2023 Annual Report

    As part of the Department of Homeland Security’s (DHS) Science and Technology Directorate (S&T), the Chemical Security Analysis Center (CSAC) is the nation’s only federal study, analysis and knowledge management center for assessing the threat and hazard(s) associated with an accidental or intentional large-scale chemical event or chemical terrorism event in the United States.

  • Optimizing Radioactive Contamination Screening at Community Reception Centers Report

    The National Urban Security Technology Laboratory (NUSTL) prepared the “Optimizing Radioactive Contamination Screening at Community Reception Centers Report” to provide emergency response organizations with technical guidance for deploying CRC radiation detection equipment to optimize screening efficiency.
