About half of the campuses in the Keller school district will receive some type of security upgrade over the summer.At the April 26 board meeting, trustees approved the expenditure of about $2.1 million to replace outdated fire systems at five schools, cameras at three campuses and digital video recorders at 19 KISD facilities. Funds will come from 2008 bond savings.“Most of the fire systems were put in when schools were built and have never been upgraded,” said Kevin Kinley, director of safety and security. “We’ve lost the ability to purchase replacement parts.”Fossil Ridge High School, Keller Middle School, Florence Elementary School and Whitley Road Elementary School will receive the new fire system panels at a cost not to exceed $550,502.Fossil Ridge, Central High School and New Direction Learning Center will have all analog security cameras replaced by digital Internet protocol cameras. Crews will also install additional cameras in areas that haven’t had coverage, Kinley said. Fossil Ridge will receive 122 cameras, Central 107 and New Direction 25; total cost is close to $1 million.Kinley said crews will work over the summer to install the cameras.Nineteen facilities will get new digital video recording systems from Salient Systems that allow officials to access video feeds online. Last year, Salient DVRs were installed at 22 schools; this round will get the rest of the schools plus several other KISD buildings. The budget for the DVRs is just under $600,000.According to the Salient Systems website, the company has surveillance systems installed throughout the Houston school district, the largest in Texas.
