I've heard the technology is also in use to monitor corporate offices. They can track how many cars are in the parking lot and even what makes/models are showing up to indicate the rate the company is hiring or laying off workers and whether the employees are trading up to pricier models. Similarly, infrared cameras are used to constantly monitor power stations (e.g. smoke stacks, cooling towers) to gather data on what level of capacity they are running and if there are any undisclosed shutdowns. Workers in ports are paid to monitor incoming tankers to record what their draft is to calculate how much oil/whatever they are carrying. If they are resourceful they can even gather intel about what % of different grade materials are on the ships. This is used to track / estimate commodity flows and pricing. Data == $$$
