Police say the vandalism occurred in Nassau County on Aug. 1 between 2 a.m. and 4 a.m., nearly a year after the technology went into effect.
Cameras at five intersections were hit, in Carle Place, East Garden City, East Meadow and Westbury. Authorities are investigating and reviewing tapes from the cameras, which sit on poles as high as 16 feet.
The cameras are projected to generate more than $13 million for Nassau county this year.
The sprayed cameras were put back in service within 24 hours.
