quotes a report from Fast Company: When the Olympic Games begin next month in Rio de Janeiro, billions of people are expected to watch athletes from countries around the world compete. But also watching over the Olympic and Paralympic events will be a set of futuristic, balloon-mounted surveillance camera systems capable of monitoring a wide swath of the city in high resolution and in real-time. Initially developed for use by U.S. forces in Iraq and Afghanistan by Fairfax, Virginia-based Logos Technologies, the technology is sold under the name Simera, and offers live aerial views of a large area, or what the company calls 'wide-area motion imagery,' captured from a balloon tethered some 200 meters above the ground. The system's 13 cameras make it possible for operators to record detailed, 120-megapixel imagery of the movement of vehicles and pedestrians below in an area up to 40 square kilometers, depending on how high the balloon is deployed, and for up to three days at a time.
The Rio Olympics marks the "first time [Simera] will be deployed by a non-U.S. government at a large-scale event," according to the company. Simera is being compared to a live city-wide Google Maps combined with TiVo, as it can let law enforcement view ground-level activities in real time in addition to letting them rewind through saved images. Doug Rombough, Logo's vice president of business development, says the image clarity is not good enough to make out individual faces or license plate numbers, though it is clear enough to follow individual people and vehicles around the city. "However, a higher resolution video camera attached to the same balloon, which captures images at 60 times that of full HD resolution, or 15 times 4K, at three frames per second, will allow operators to get a closer look at anything or anyone that looks suspicious," reports Fast Company.
