On-board video storage on the edge using an SD card has gained traction lately in the video surveillance world. The main reason is that today’s SD cards offer substantially larger storage capacity at a substantially lower cost than in years past.
“A 1 GB card used to cost around $100 only a few years ago; today you can buy a 32 GB card for under $40 or $50,” shares Fredrik Nilsson, general manager for Chelmsford, Mass.-based Axis Communications. “Moore’s Law continues to push the consumer storage market forward with more capacity for less cost. Soon SD cards will be able to hold upwards of 2TB. That’s years’ worth of storage at the edge.”
