Megapixel cameras (like those from Arecont Vision in video below) are already at work around the world in large and small applications in every vertical market. Some examples include
- A major grocery distribution center in the United States that uses a 20-megapixel, 180-degree day/night panoramic megapixel camera to provide a complete view of its property.
- In South Korea, a single 2-megapixel camera is being used to cover three lanes of traffic and deliver the resolution required for license plate recognition analytics across all three lanes.
- A jewelry retailer in Mexico uses a handful of megapixel cameras versus a dozen or more conventional cameras to monitor jewelry showcases and restricted areas in the store office and workshop.
- In Hawaii, megapixel cameras are part of an overall effort to protect tourism by supporting public safety. Several factors are converging to make megapixel technology an increasingly mainstream component in video surveillance systems worldwide.

The growing video feeds are also pushing new paths in storage and analytics as this article from the same issue details
Now that many organizations have experience with deploying and managing large numbers of cameras, Caswell says they are beginning to investigate how video data can be used for more than just forensic purposes (e.g. using video as evidence or for prosecution purposes). The next step in the evolution of surveillance systems includes using video to provide a realtime indication of what is happening. "This involves video analytics," Caswell says. "If you have a camera on a TSA (Transportation Security Administration) line at an airport, for example, you can predict that all of the pixels should be moving the same way. If you see pixels going the other way or in an unusual arrangement, you can analyze those and send alerts. You look at the aberrations."
