GE Security is mainly aimed at businesses (medium to large), organizations, and governments, but products from GE Security are available for both residents and small businesses. GE Security includes different families of detection systems, web-based surveillance systems, and aviation security products, such as handheld and walk-thru explosive/narcotics portals. Much of General Electric's fire systems came from the acquisition of Edwards Systems Technology from SPX Corporation in May 2005.
On November 12, 2009, GE Security announced that it had signed a definitive agreement with United Technologies Corporation for UTC to acquire GE’s Security business for $1.82 billion. The transaction was approved by the boards of both companies, and the sale closed on March 1, 2010.
