YORKVILLE, Ill. — Kendall County officials will spend $3 million to improve security at their county jail and courthouse.

The (Aurora) Beacon-News reports (http://trib.in/2ddrLSu ) the county board approved a contract with Security Automation Systems. The Indiana-based company was one of four to bid on the work.

Sheriff Dwight Baird says work will include a door interlock system and new surveillance cameras. He says video from current cameras is difficult to search and the cameras produce images too grainy to be beneficial close up.

The new system has a search function that will move to a programmed time automatically instead of requiring officials to watch through the entire archive.

And the cameras will cover current blind spots.
