STATEN ISLAND, N.Y. -- There are two types of school zone speed cameras: Fixed cameras attached to poles, and mobile cameras perched on the tops of Ford Escorts parked in school zones.

The city has installed six fixed speed cameras on Staten Island and has tested mobile cameras at about 30 locations on the Island since June.

From June 2014 through March 2015, speed cameras on Staten Island have issued $2.9 million in summonses. Citywide, cameras have collected $12 million in speeding fines in that same window.

SPEED CAMERA PROGRAM

Speed camera data has documented a 55.4 percent drop in speeding, though the cameras haven't significantly impacted the number of car accidents on the Island that occur nearby.

Check the map below to see where cameras have issued tickets dating back to June 2014 through March of 2015.

Here's a statistical breakdown of the six fixed cameras on Staten Island:

GOETHALS ROAD NORTH AT JULES DRIVE

This camera is located near the Staten Island School of Civic Leadership in Graniteville and tracks traffic heading westbound, right near the South Avenue exit of the Staten Island Expressway.

It's by far the highest-grossing camera in the borough, collecting more than double the number of summonses than the rest of the Island's cameras combined. It's considered a "speed trap" by some, though the Department of Transportation insists otherwise.

HYLAN BOULEVARD AND TYSENS LANE

According to city data, this was the first fixed speed camera installed on Staten Island, with summonses dating back to January of 2014.

It was originally installed close to the front entrance of the Richmondtown Preparatory Schoo. But after the school moved locations last year, this New Dorp camera remained in operation. The DOT justified its continued use by considering a Hylan Boulevard entrance of St. Charles Church as part of the adjacent St. Charles School campus. Critics have questioned the legality of its use.
