ESE was founded in 1971 in El Segundo, California. The co-founders' objective was two-fold; first to ESE's customers, "... to provide quality products, delivered on time along with excellent service" and also first to ESE's employees, "... to provide both a pleasant work environment and a stable company which can survive and grow as time marches on". In 1996, NENA (National Emergency Number Association) issued the Technical Reference NENA-04-002 for a Public Safety Answering Point (PSAP) Master Clock Standard. At the NENA'97 Conference and Trade Show, ESE introduced the ES-911/GPS. The ES-911/GPS, designed to meet the specifications described in the NENA- 04-002 Standard, has spearheaded ESE's commitment into the Public Safety Sector.  ESE products provide the perfect way to enhance any of BEI's Digital Recording and Call Logging solutions!
