Question: Are those traffic surveillance cameras installed at the intersection of Bedford and Hill streets? If they are cameras, what’s the purpose? Are they license plate readers? This seems like a minor intersection.  

Answer: Those camera-looking devices are not cameras at all, according to the Lexington Police Department. Actually, they’re sensors meant to tell the traffic lights when there’s a vehicle at the stop line. These kind of sensors used to be underground, but now they’re positioned up with the lights. While they won't read your license plate, police say the sensors should prevent motorists from getting stuck too long at the intersection when they’re the only traffic in the area.
