 Flock Safety is a surveillance company that specializes in reading vehicle license plates and then feeding that data to law enforcement. Many homeowners associations have contracted with Flock to install and maintain cameras to catch neighborhood thieves and vandals, which is great if you're a homeowner paying for the service. But now Flock has partnered with FedEx to use the cameras in their 40,000 trucks roaming around in more than 4,000 cities and towns across America.
