(PSI) teamed with the Center for Society Law and Justice (CSLJ) and the Department of Justice / Office of Justice Programs entered into a cooperative agreement for the deployment, operation and analysis of an acoustic gunshot detection system in Newport News and Hampton Virginia. The National Institute of Justice (NIJ) – Office of Science and Technology, oversaw the project. Chris Miles, Senior Program Manager, Sensors, Surveillance, and Biometrics provided oversight and direction on behalf of NIJ. The SECURES® acoustic gunshot detection system deployed in Newport News and Hampton, Virginia represented the third generation of hardware electronics since its original inception. This report is presented in two basics sections. The first section represents the findings by CSLJ as an independent third party assessor with scientifically founded conclusions based on research and statistical data collected during the operation of the system including independent Live-Fire tests conducted in Newport News and Hampton, Virginia. The second section of this report is the overview of deployment and operational initiatives as reported by PSI personnel. The conclusions drawn by CSLJ are impressive. Some of the most notable include: o The Live-Fire tests conducted in Newport News and Hampton, though differing in actual results, suggest that the detection of handguns by the SECURES® system, particularly in calibers of 9 mm and greater, is very accurate. o The ability of the SECURES® system to locate gunshots was very accurate often localizing the actual test shot location within a 10-foot radius. o Trade-offs between detecting true positives and false positives was noted wherein false positives can be reduced to near zero with relative small loss in true positives. o Indications exist that public awareness of the SECURES® system may serve to decrease the number of gunshot relate 911 calls. o Eleven (11) arrests were made as a result of SECURES® related dispatches that can conservatively attributed solely to the SECURES® system deployment. o In Newport News there were four gunshot victims found on SECURES related dispatches of which one would not have been found otherwise. The other three gunshot victims found were incidents where associated 911 calls also existed. The deployment and operations of the SECURES systems in Newport News and Hampton were completed under best practices as known at the time deployed. These initiatives, as with most projects, were met with challenges that have been overcomed. The information gained in these efforts, though beyond the scope of these demonstrations, have subsequently been used in other deployments to further stream line deployments and operations.

Author: Planning Systems, Inc. Title: Draft Technical Report for SECURES Demonstration in San Bernardino County - Bloomington Area Summary: In October 2003 Planning Systems Inc. (PSI) teamed with the Center for Society Law and Justice (CSLJ) and the Department of Justice / Office of Justice Programs entered into a cooperative agreement 2003-IJ-CX-K021 for the deployment, operation and analysis of an acoustic gunshot detection system in San Bernardino County California. This report is presented in three basic sections. The first section provides an overview of the enhancements to the technical tools used in the deployment of the SECURES® system and to the SECURES® display software. The second section of this report is the overview of deployment and operational initiatives as reported by PSI personnel. The third section represents the findings by CSLJ as an independent third party assessor. The use of technical tools in the form of acoustic and RF modeling can greatly enhance the deployment of SECURES® by reducing the normal amount of field manpower and time required in an empirical approach to sensor and receiver placement and installation. This enables police departments to deploy or even relocate a SECURES® system in minimum time with limited exposure within the area of deployment. Not only does this save time and costs in installation but it also has the ability to identify deficient areas in advance so that these can either be re-engineered to assure coverage by the system being deployed or can provide additional situational awareness to patrol officers. Enhancements to the SECURES® display software provides dispatch personnel with better tools to more accurately define and convey the gunshot locations to patrol. The deployment and operations of the SECURES® systems in was plagued by delays in securing a valid poly use agreement with the local providing utility, Southern California Edison (SCE). Much progress was made with the onset of the program in 2003 including software enhancements, system layout, training and even the initial installation of the receiver and base station assemblies. However, once the issues concerning the pole use agreement for the intended area was overcome in 2007 with separate pole use agreements with both SCE and AT&T (formerly PacBell) much of the enthusiasm developed earlier on with all parties concerned had dissipated. Nonetheless the system was deployed as intended. The results gained from the assessment by CSLJ were disappointing. The area in which SECURES® was deployed netted few gunshot alerts. There were no corroborating reports from the SBCSD to support actual ground truth events. The span of time from initial time of planned deployment in 2003 to actual deployment in 2007 had not only diminished enthusiasm but also the resources available to support this effort locally.
