Agenda

• Overview
• Video Surveillance
• History
• New Technology
• IP Video
• Camera Technology
• Integration with Gunshot Detection
• License Plate Recognition
• Moving beyond traditional applications

3
Overview

• Video Surveillance is not new
• New enabling technology is changing how and where
  it is used
• License Plate Recognition is newer but relies on
  the same underlying technology
• The two technologies can be effective tools in
  crime prevention and investigation.

History of Video Surveillance

• Video Surveillance has been around for many
  years. It was often referred to as CCTV.
• Early systems were typically black white (BW)
  and used point to point coaxial cables to each
  camera.
• Some (not all) included recording devices
• Resolution was typically poor and quality of
  recordings was even worse as media was used over
  and over.

New Systems Are More Advanced

• Analog has been replaced by digital
• Color has replaced BW
• Cameras can include night vision
• Camera resolution is much higher
• IP Transport has replaced coax cable
• IP over network class cabling and wireless
• VHS recording systems have been replaced by DVD
  and DVR systems

Video in Criminal Justice

• There is heavy use of video technology in
  criminal justice
• Video Arraignment has been very successful in
  reducing Jail transportation costs
• Video Visitation has reduced the introduction of
  contraband during jail and prison visitation

Innovations in Video

• Video is going mobile
• Both cameras and viewing technology are going
  mobile
• Seal Beach PD did a system to display bank
  cameras in patrol vehicles

Integration with Gunshot Detection

• The integration of Video Surveillance with
  Gunshot Detection has proven successful in high
  crime areas

12
Video Analytics

• Systems are being developed that will allow video
  surveillance systems to proactively look for
  items of interest

Outcomes

• Calls for service have been reduced by 42 in
  areas with heavy video presence
• Narcotics offenses have been reduced by 76
• Serious criminal acts down 17
• Misc criminal acts down 46

14
The Future

• Camera systems are proliferating across the
  country and the world
• The are very effective for criminal
  investigations
• However, for them to be used to proactively
  prevent crime, new technologies must be used
• There are not enough eyes to watch all the
  cameras
• The technology must do the watching

15
License Plate Recognition

• License Plate Recognition is the marriage of
  video imaging and digital pattern recognition
• LPR is used in many applications
• Access control
• Parking, Traffic, and Toll Enforcement
• Asset Protection
• Cameras can be fixed or mobile

Typical Public Safety Applications

• Toll Lane Enforcement
• Speed Enforcement
• Red Light Enforcement

New Directions for LPR

• Like Video Surveillance, LPR is going mobile
• Situational Awareness
• Area Surveillance
• Systems that can quickly inventory a parking
  lot or other parking area
• Mobile Vehicle Identification
• Checking vehicles in the field of view of a
  patrol vehicle and checking against a hot sheet

18
Mobile LPR is already proving itself

• San Jose PD used the technology to quickly locate
  a stolen car used in the abduction of a 12 year
  old.
• CHP has also had enormous success

Wrap Up

• Video Surveillance and License Plate Recognition
  technologies are evolving rapidly
• Both are effective tools for both crime
  prevention and criminal investigation
