Evolution of Video Surveillance Presentation Transcript

  • 1. Evolution 1975 First CCTV Systems available 1985 Multiplexer / Time-lapse systems become widespread 1995 Color CCTV cameras hit mainstream Digital Video Recorders (DVR) dominate the industry 1997 First IP Cameras begin to appear on market 2005 IP Video becomes cost-effective for new and existing installations 2000 Surveillance Video History IP based video systems appear, dubbed NVR ‘Network Video Recorders’ 2002
    • Little change from 1970’s through late 1990’s
    • Explosion of features based around computerization / digital video
    • Information Technology and Physical Security / Surveillance begin to merge

  • 2. Technology
    • VCR
      • Time-lapse recording, ‘jerky’ and low quality
      • High-maintenance, wears out over time, no security or remote capabilities
    • DVR
      • Able to record and view simultaneously, limited security and remote viewing
      • Single-purpose ‘locked-in’ hardware
    • Software
      • Requires no specialized hardware, available from anywhere
      • Can provide multiple uses and applications on common hardware
      • Easily upgraded and expanded as needs and technology change
      • Programmable for custom applications and integration with other systems
    VCR Software DVR
  • 3. Industry Analogy
    • Typewriter
      • Dominated industry for decades
      • Totally physical ‘analog’ device
    • Word Processor
      • Took market by storm in 80’s and 90’s
      • Single purpose digital device, able to save and retrieve
    • Personal Computer
      • Provided multiple uses with same hardware
