Hempstead Village has installed 12 license plate reader cameras in high-crime areas throughout the village, Mayor Wayne Hall Sr. said.

The cameras are on utility poles in seven locations and are part of the village’s crackdown on crime using technology, officials said.

Hall last week said the cameras were installed by March 10 after the parts were delivered earlier that week. Officials previously said they’d hoped to finish the installation by the end of February. There was no additional cost for the delay.

Village Police Chief Michael McGowan has said he wants to double the number of locations covered by the cameras within a year.

The board of trustees in February authorized the purchase and installation of the cameras for about $200,000. The cameras are made by Elsag North America, based in Brewster in the Hudson Valley.

Hempstead officials said they hope that Nassau County will provide additional units for village use.
