About Us.

EXTRANET SYSTEM TECHNOLOGY SDN BHD(EST) was registered in 1992 as a specialist in Closed Circuit Television System (CCTV) and Burglar Alarm System. The company was formed to meet the increasing demand from the residential and commercial sectors for security systems. As a security specialist, we are fully committed to provide reliable service to our clients and to ensure a safe and secure environment that can complement the preventive measures being taken by the Malaysia Police.

Although our company was registered on in 1992, we had actually been operating for the last Eleven years under the name of our parent company Harmonic AV Centre, which is also the HUPER Center in Johor. The separation was decided in 2002 as both lines of businesses (i.e. security systems and sale of audio visual products) have experienced significant growth over the years. Moreover the name of Harmonic Security Engineering would put the nature of our business in the right perspective.

Since 1997 we were appointed as the authorized dealer and 2001 as the authorized system integrator in Johor by Bosch Security Systems Sdn Bhd (formerly known as Philips (M) Sdn Bhd). The appointment comes with the responsibility to devise and design appropriate security systems for our clients. In this aspect, we are backed by the experience and expertise of our technicians and installation crew who have been systematically trained by Bosch Security Systems Sdn Bhd.

Our personnel are professional, reliable and highly trained to meet the high standard in provision of security system and above all, peace of mind.
