It seems the traffic camera craze will never end; it started in Clive, and then spread to Des Moines and Windsor Heights, now Polk County wants automated cameras to help police the streets.
Sheriff Bill McCarthy told the Des Moines Register his department could have two mobile speed cameras as early as May first.
McCarthy says the cameras will be installed in vehicles and parked along highways where speeding in a problem. They will also be able to take photos and issue tickets while being driven down the road.
Polk County expects the two cameras to generate $479,000 in revenue in the first year.
