In collaboration with the FBI, NIST conducted research to define and recommend an interoperable data solution to assist law enforcement in acquiring and analyzing digital video evidence from disparate systems. This document supplements the recommendation developed in NISTIR 8161, Recommendation: Closed Circuit Television (CCTV) Digital Video Export Profile Level 0. This supplement describes the research activities, methods, and results that led to the recommended standards profile. It also provides web links to the sample files used to conduct the research and validate implementation of the recommendation. NIST welcomes and seeks continued industry and other stakeholder comments concerning the initial (Level 0) recommendation and potential future enhancements. NIST looks forward to identifying and working with the pertinent standards community to move the recommendation into a formal standard that becomes adopted widely by industry.
Bluetooth
wireless technology is an open standard for short-range radio frequency
communication used primarily to establish wireless personal area networks
(WPANs), and has been integrated into many types of business and consumer
devices. This publication provides information on the security capabilities of
Bluetooth and gives recommendations to organizations employing Bluetooth
wireless technologies on securing them effectively. The Bluetooth versions
within the scope of this publication are versions 1.1, 1.2, 2.0 + Enhanced Data
Rate (EDR), 2.1 + EDR, 3.0 + High Speed (HS), 4.0, 4.1, and 4.2. Versions 4.0
and later support the low-energy feature of Bluetooth.
At a time when more than 70% of the calls
made to 911 are placed from cell phones, it is vital for Public Safety
Answering Points (PSAPs) to be able to dispatch emergency responders to the right
location for the caller. A major challenge in this area is the location
accuracy of E911
calls placed from
inside buildings. The Safety App
from 911Cellular, LLC is a Wi-Fi-based app for placing E911 calls. In December
2016, NIST tested and evaluated the Safety App in a comprehensive manner
according to the procedures of the international standard ISO/IEC 18305, Test and
evaluation of localization and tracking systems, in a large, four-story
building on the NIST campus in Gaithersburg, Maryland. The Safety App achieved
an average horizontal accuracy of 7.45 meters, it had a horizontal accuracy of
15.11 meters or better in 95% of the area of the building, and correctly
decided from which floor the E911 call was placed in 87.6% of the area of the
building. These results for a technology that is available today are far better
than what FCC rules have called for by 2021.
This handbook provides an overview of the user-centered design process and examples of how the process can be applied to the design and development of communications systems for the public safety community.
