Tech currently being tested in Europe and the Middle East could come to US.
Call it the next generation of light bars. Ekin Technology, a Turkish law enforcement technology company, was recently granted an American patent for what just might be the surveillance trifecta: a light bar with an integrated license plate reader (LPR), speedometer, and facial recognition capability.
If the "Ekin Patrol" catches on in the United States, it will facilitate a notable acceleration in the advancement of spy tech. While speedometers are relatively old and LPRs are increasingly catching on, facial recognition technology is not yet widespread in America. Agencies ranging from the FBI to the California attorney general's office have expressed their interest in the technology.
