Recently my neighborhood had a rash of car break-ins by what turned out to be just a band of mischievous teenagers. But what struck me about this occurrence was the flood of homeowner video surveillance clips that appeared on social media and that were sent to the local police department to help identify the wrongdoers. It seems like everyone in the neighborhood has a home video surveillance system, perhaps to catch a doorstep package thief, or if nothing else, to catch the guilty dog walkers!
A Booming Market for Video Surveillance Solutions
Indeed, the video surveillance market is booming, not just in the relatively nascent consumer market, but in the commercial market and has been for a long time – in a much bigger way. The reasons for this include more affordable cameras with better resolutions soaring from 720p up to 4k and even 8k. In the meantime, video surveillance systems are finding more and more applications. Retail shopping malls, banks, hotels, city streets, transportation and highways, manufacturing and distribution operations, airport security, college dorm and campus security, corporate security, police body and dash cams, to name just a few – all need good quality video surveillance.
Video Retention Costs Soar
However, these higher resolution cameras have sent the costs of video retention soaring. So much high-resolution raw footage quickly fills up available hard disk drives commonly used to store or retain video surveillance content. According to a Seagate video surveillance calculator, an installation of 100 cameras recording eight hours a day at 30 frames per second, 1080p resolution, with a retention period of 90 days would require 2,006 terabytes of storage. That’s 2.0 petabytes of expensive, energy-intensive hardware. Those with unlimited budgets can simply add more disks. But everyone else faces tough choices: shorten retention periods? lower video resolution? reduce the number of cameras or frames per second? None of these support the goals of why the video surveillance system was installed in the first place.
