Public High School CCTV Case Study



Provided the evaluation, design and implementation of a physically security system that provided security personnel and school administrators, along with a centralized school security office, with two primary requirements: 1) Facial identification at 30-40 feet, and
2) Near 100% corridor coverage.

Historically, they were able to see a person-of-interest, but not be able to recognize them due to the limited resolution and frame rates of the existing cameras and limitation of the video management system software. I provided an evaluation and design, using megapixel cameras and increased coverage, along with video management system configuration that dramatically increased the effectiveness and efficiency of the physical security system. The success of the implementation lead to the integration into 14 more schools.

Real world statistics of the effectiveness and efficiencies include:

  • 79 percent decrease in arrests (over 140 in 2009)
  • 59 percent drop in misconduct reports
  • Reduced onsite Police officers
  • Identification and arrest of burglary suspects
  • From July to November 2011, 16 arrests saved hundreds of thousands of dollars in assets
  • Increased test scores
  • 67% reduction in index crimes
  • Six percent increase in attendance
  • Video analysis reduced from 8+ hours to minutes
  • False Fire Alarms from eight per year to zero

New Edition of Digital Video Suveillance and Security

Working on a proposal for the new edition of Digital Video Suveillance and Security! I will be adding much more information including the importance of a architectural approach to design; more about Physical Security integration and the PSIM; more on wireless networked video; adding how to break down work into a task-oriented schedule and more. What else would you like to see? Email me at newedition (at) dvsbook dot-com.

Fiber for Intrusion Detection

Working on a project that includes intrusion detection along a fence perimeter. Fiber Sensys uses multimode fiber installed onto the fence as a media to sense vibrations at various levels.

FiberSensys uses a single strand of multimode sensing fiber installed onto the fence as a designated “Zone” (up to 25 zones with the FD525). This single strand is fusion spliced onto a fiber trunk (singlemode or multimode - doesn't matter) and then must be terminated using either ST/APC, SC/APC or LC/APC connectors (color coded green) at the patch panel. APC jumpers connect from the fiber patch panel to the Fiber Sensys fiber splitter and then connected via a single SC/APC jumper into the FD 525 Fiber Sensys Alarm Processing Unit (APU) which will include an I/O module to be wired into an alarm system and VMS system via I/O interfaces.

The moment someone tries to climb the fence, configured PTZ cameras in that area turn to that zone's preset and begins recording and auto tracking. Slick!
