A few years ago, when you saw a security camera, you may have thought that the video feed went to a VCR somewhere in a back office that could only be accessed when a crime occurs. Or maybe you imagined a sleepy guard who only paid half-attention, and only when they discovered a crime in progress. In the age of internet-connectivity, now it’s easy to imagine footage sitting on a server somewhere, with any image inaccessible except to someone willing to fast forward through hundreds of hours of footage.
That may be how it worked in 1990s heist movies, and it may be how a homeowner still sorts through their own home security camera footage. But that’s not how cameras operate in today’s security environment. Instead, advanced algorithms are watching every frame on every camera and documenting every person, animal, vehicle, and backpack as they move through physical space, and thus camera to camera, over an extended period of time.
