The one truism in technology is that it’s constantly evolving. In fact, the growth of technology performance and capabilities is difficult to keep up with.
Most are familiar with “Moore’s Law,” the observational theory of Gordon E. Moore that predicted the doubling of hardware performance every two years – theorized initially in 1965, Moore’s law has predictably described the driving force of technological change ever since.
Video cameras, of course, are no exception to the rule. Big innovations have ranged from tilt-pan-zoom (TPZ) to, of course, the transitional leap from analog to digital. Cameras are still improving, and stereo camera capability and functionality continues to grow with each passing quarter.
Stereo cameras are cameras with two or more lenses with separate image sensors for each lens (as opposed to a singular lens for monocular cameras). Stereo cameras simulate humans’ own binocular vision, with perhaps the most widely-known application being 3D video.
In the retail environment, stereo cameras allow for depth perception, and can provide an entirely different data set for retailers – for example, excluding children from shopper traffic counts. In the quick video below, Arun Nair, co-founder and CTO of RetailNext joins George Shaw, head of R & D, for a quick primer of what stereo cameras are and what benefits they provide.

For the purposes of retail analytics, camera deployments are contingent on a retailer’s specific needs, but often include a combination of camera types and form factors. Key for an analytics company like RetailNext – and its customers – is to be flexible enough to accommodate and integrate a variety of camera sensors.
After all, Moore’s law says new hardware is coming and coming quickly – the “next big thing” is just an inspiration away.
