Golmar Sistemas de Comunicación S.A. was set up in 1954, and one year later it manufactured its first intercom. The first door intercom was developed in 1958, followed some years later by the video door intercom, which is nowadays the most important product. More recently, based on its wide commercial network within Spain, it has expanded to the imports and sales of closed circuit TV and public address systems. Golmar was the first Spanish company in the industry to obtain the ISO 9000:2000 Certification, granted by the prestigious Swiss company SGS since 2001.
