Growth of big data spurs demand for HD surveillance solutions

The rise of big data within video surveillance has caused an influx of high-definition video cameras in the market, according to a new report from IHS. With increased shipments of HD cameras, however, the daily data dump from these devices is expected to more than double over the next four years, expanding to 859 petabytes in 2017.

IHS says that this quantity of information will require the use of technologies designed to handle and process big data in surveillance.

"HD-compliant products are set to account for an increasing share of video surveillance camera shipments during the next four years," Sam Grinter, senior surveillance analyst at IHS said in a statement. "These cameras are gaining acceptance because the quality of their video can be superior to standard-resolution products that formerly dominated the market. But because each HD camera produces far more data than each standard-definition camera, the quantity of data generated by the surveillance market is growing to massive proportions."

The research firm said that surveillance industry is adopting several technologies designed to accommodate and mitigate the rising tide of data including:

  • New data compression algorithms, which should help cut down on the quantity of data. For example, the High Efficiency Video Coding (HEVC) standard—also known as H.265—has been claimed to double the data compression ratio when compared to H.264, which should reduce the amount of data produced per camera in the coming years.
  • Development of video content analysis, which can be used to reduce the amount of time a video surveillance camera is recording by using virtual tripwires and no-entry zones. Virtual tripwires and no-entry zones can trigger a camera to record once a predefined event has occurred, such as a person entering a parking lot. This means than only important events will be recorded by video surveillance cameras, rather than simply recording continuously. 
  • Innovation can also be found in hard disk drives (HDDs), according to IHS, where capacities are increasing. While the amount of data produced per camera is expanding, so is capacity to record that data—either on site or via networked systems.
