Schools across the country are reassessing security measures in response to a wave of school shootings.
They’re investing in video surveillance, entry control systems, lockdown training and armed police on site. And some are considering newer gadgets that claim to fill security gaps, including door barricades and bulletproof backpacks.
School security is a rapidly expanding business, according to research by Jim Dearing, senior security analyst at IHS Markit. The education sector of the security market grew to $2.7 billion last year, up from $2.5 billion in 2015. The proportion of schools using video surveillance grew to 70% in 2013, up from 20% in 1999.
