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

Outline for Networked Video Troubleshooting


  poor video/no video
a.       power
                                                               i.      if powered, reboot device to see if it improves - check power load and quality of power
                                                             ii.      no power - check to see if other devices are accessible at location, if so, investigate power source for device
b.      wireless (if applicable)
                                                               i.      continuous ping of gateway or network switch to determine quality of wired network ( in command prompt type: ping [ip address] -t
                                                             ii.      continuous ping slave radio to determine stability
                                                            iii.      if erratic ping times, test wireless bandwidth
                                                           iv.      test for wireless interference
                                                             v.      increase or decrease wireless channel size (depending on interference issues)
                                                           vi.      check antenna alignment
                                                          vii.      check antenna cable for damage, poor termination
                                                        viii.      check for firmware upgrade on wireless radios
                                                           ix.      test connectivity with a known-good device
                                                             x.      reset to factory default and reapply configuration to determine if there's corrupted firmware
c.       video settings
                                                               i.      check recommended video settings (make sure it's on the best compression codec method for transport (e.g. H.264 vs MJPEG, which uses 10x more bandwidth)
                                                             ii.      reduce frame rate to see if it improves - improvement indicates limited bandwidth issue
                                                            iii.      check for firmware update for camera/encoder
                                                           iv.      check for updated driver in video management system software
                                                             v.      test connectivity with a known-good device
                                                           vi.      reset to factory default and reapply configuration to determine if there's corrupted firmware
d.      network
                                                               i.      check method of transport - TCP vs UDP (UDP is a better method for data transport for synchronous, continuous video streaming as it does not require an acknowledgement for each IP packet delivered)
                                                             ii.      use Wireshark (network protocol analyzer) to sniff out data throughout network to determine if there's a broadcast storm
                                                            iii.      any dumb switches? determine if device is being overloaded or malfunctioning
                                                           iv.      check firewall settings for transmission and authentication

ISC West 2014 Educational Seminar

2014 SIA Education@ISC West Program

Thursday, April 03, 2014: 8:45 AM – 9:45 AM

Troubleshooting Networked Video

This session features an extensive step-by-step four-dimensional view of all the components for a digital video surveillance system, including power (electrical), software (video management systems, PSIM, networking), hardware (cameras network switches, radios), and communications (OSI layers, wireless, fiber). Session participants gain insights on real-world video surveillance case studies and explore details of how to utilize troubleshooting charts to save time and money, and observe details on the complexity of the IP solutions currently being implemented by traditional CCTV hardware-driven integrators and architects.

Learning Objectives:

  • Discuss network hardware and software issues and restate the multidimensional view of troubleshooting complex digital video surveillance systems.

  • Distinguish components of camera, networking and wireless issues.

  • Interpret signals and clearances for antennas, Fresnel zones, cabling and polarization.

  • Recognize best practices for design and implementation.
