Big Data, SD Storage, Business Intelligence Articles

newsSeveral articles floated up recently that are worth review:

1. Business Intelligence in Retail

From Axis Communications, a summary of a LPRC study commissioned in late 2012 that addresses retailers’ adoption and use of IP video. Not surprisingly, the data shows an increase in the number of companies seeking sales, operations, and marketing improvement through the use of intelligent video (video analytics). This is reassuring, since image quality and resolution have been consistently discussed as the primary motivators, while their value continues to be debated. Of the ~25% of respondents who reported that business intelligence was a primary factor in selecting IP video:

  • People Counting was by far the most used non-LP analytic application, with 46.3 percent of
    respondents deploying this feature, up from 27 percent in 2010;
  • Dwell Time Analysis (20 percent) and Heat Map or Hot/Cold Zone (18.2 percent) usage
    increased in 2012, while 38.3 percent of respondents use video analytics to detect POS fraud;
  • Queue Counters are used by less than 10 percent of companies surveyed, yet 50 percent say
    they may use this application in future. Similarly, while no respondents said they utilize Out of
    Stock Alerts today, more than 56 percent say they may use them in the future;
  • Nearly 32 percent of respondents utilize surveillance to help analyze “shopping & buying
    behavior,” with 20 percent using video to measure shelf and product placement effectiveness

2. Big Data Requires a Cautious Approach

Beware the Errors of Big Data summarizes Nassim Taleb’s position that big data must be used with great care in order for it to be useful. His primary observation is that “modernity provides too many variables, but too little data per variable. So the spurious relationships grow much, much faster than real information. In other words: Big data may mean more information, but it also means more false information.”

He asserts that this is not necessarily bad, however, since big data can be effectively used to debunk a theory or conclusion, rather than draw new conclusions whose basis is made questionable by big data.

As the claims around big data continue to make their way into the video intelligence, security and integration space, the article (and the author’s book, Antifragile) are worth a read.


3. SD Card Video Storage (recording at the edge)

From SDM Magazine comes an article on the current state of SD card (flash memory) storage for video. While it only addresses the current trend of cameras supporting off-the-shelf SD memory cards, and not more reliable types of flash memory, the article does touch on some of the applications and limitations of this approach. Thanks to demand from the consumer market – driven by tablets, high megapixel cameras, and ultrabooks – the capacity, cost and reliability of SD cards is improving constantly. For many commercial and residential applications, it is virtually certain that this type of distributed recording will be the norm in just a few years. It will be a welcome and exciting change for end users and service providers – and a terrifying one for DVR/NVR vendors who haven’t yet figured out their migration to a cloud/SaaS model.
