  • We appreciate your references to the HDcctv standard, but it looks like you didn't read the text that you quote within your presentation.

    HDcctv is a digital technology, not analog.

    HDcctv cameras are incorporated in IP-based digital surveillance systems better than IP cameras are, in many cases.

    HDcctv-based systems are more cost effective than IP-camera-based systems in the general case, and the economic fundamentals ensure that the advantages of HDcctv will only continue to increase.

    HDcctv is like USB for local-site transmission of HD video surveillance signals. USB interfaces co-exists with IP networks in the I.T. world, and there's every reason to expect HDcctv interfaces to co-exist with IP networks in the surveillance world.

    It is incorrect to assume that IP cameras offer intrinsic benefits for surveillance in the general case. IP video is very powerful, and in fact IP video already has attained nearly 100% market share in surveillance

    The question remains whether converting to IP in a camera, instead of elsewhere in a local site such as a DVR or multi-channel IP encoder, is most cost effective. The answer varies from case to case, and H. Sandstrom is incorrect to assume that IP cameras are always the right choice, or always will be the right choice.

    An informative analogy would be PCs and mobile phones. All of these offer connectivity to IP networks. And they all also offer other interfaces, including USB and HDMI and audio, for example. It is not optimum to carry every signal over IP networks. HDcctv is like USB for local-site transmission of HD video surveillance signals.

Technology sailing effects Presentation Transcript

  • 1. The Sailing Ship Effect
  • 2. Christian Sandström holds a PhD from ChalmersUniversity of Technology, Sweden. He writes and speaksabout disruptive innovation and technological change.
  • 3. This presentation introducesand explains the concept of a Sailing Ship effect. 3
  • 4. In order to do so, the concept of a technology S-curve will be described first. 4

  • 9. Performance Limits of what is scientifically possible are reached and performance doesn’t increase much more. A technology’s At some point, a performance breakthroughevolves slowly in happens and it now the beginning. improves rapidly. Time 9
  • 10. When one technology is displaced by anothertechnology, the pattern might look something like this: 10
  • 11. Performance Time 11
  • 12. Performance The initially lower performance makes it seemingly irrational for firms dominating the previous technology to invest at an early point. Time 12
  • 13. When the establishedtechnology is threatened, this usually triggers existing companies to improve it. 13
  • 14. Such improvements are referred to as a sailing ship effect. 14
  • 15. This notion comes from anobservation by Gilfillan (1935)who noted that the best sailing ships were produced when steam ships had already displaced them. 15
  • 16. A Sailing Ship effect can beillustrated in the following way: 16
  • 17. Performance Time 17
  • 18. Performance Time 18
  • 19. Performance The threat of being displaced triggers investments in the established technology, increasing its performance. Time 19
  • 20. Performance But it is too late and the new technology wins in the long term. The threat of being displaced triggers investments in the established technology, increasing its performance. Time 20
  • 21. Some examples: 21

HDcctv is the worlds only electrical interface standard for HD surveillance video, providing 100% digital transmission of uncompressed HDTV signals over existing coax. Seeing is believing!” 22

HDcctv is the worlds only electrical interface standard for HD surveillance video, providing 100% digital transmission of uncompressed HDTV signals over existing coax. Seeing is believing!”Analog HDCCTV is a contradiction in terms! Why this notion? And why in 2009? 23
  • 24. Analog CCTV is threatened by Digital, IP-based video surveillance. 24
  • 25. As the image quality of IPsurveillance improved and HD quality was progressivelyintroduced from 2008 and on, this put pressure on analog CCTV companies. 25
  • 26. HDCCTV can thus be regarded as a sailing ship effect. 26

  • 34. Grübler (1990) describes a sailing effect pattern in the automotive industry:“It is as if the industry itself anticipates the approaching saturating markets and tries to gain ground by accelerating the pace of incremental innovations. Note that during periods of steady, regular high growth rates (the steep part of the automobile diffusion curve) the rates of technological change appeared to be much slower. Faced with almost saturated markets, the industry appears to be forced to rapidly introduce technological innovations as part of the competitive "elbowing" in the struggle for market shares.” 34
