Our Story

Our story starts in 1966 in a small Melbourne suburb named Burwood.

NIDAC’s products stand for innovation, reliability and ease of use. These have been the hallmarks of our products from day one, and our ongoing commitment to these values is what drives us forward.

Springing from the dawn of the transistor, NIDAC pioneered the electronics security manufacturing industry in Australia.

NIDAC (which is an acronym of Nicholls Industrial Design and Applications Company) embodies the vision and inventive spirit of its founder, David Nicholls.

In 1966, David founded NIDAC Pty Ltd. The Nicholls Electronic Eye doorway alarm was the product that really launched the company. Over 50 years later, these products can still be found working in shops and retail business around Australia.

As a passionate and active member of the electronics industry, David forged close relationships with key suppliers and customers, some of which still continue. This has ensured that NIDAC’s products have always remained innovative and customer-focussed.

Through the 1970s, '80s and '90s, NIDAC produced many different alarm, detection and access control products, servicing the domestic, commercial, industrial, aviation and government sectors. These included the SPR5 alarm system, the patented CM8 alarm system, and the DT1 dialler. Also during this phase, the company won three Australian Design Awards: in 1988 for the CM8 and in 1990 for the TE3 Dialler.

Who we

are today

Since 2018, Matthew Nicholls (Managing Director) and Paula Nicholls (Director Sales and Marketing) are steering NIDAC into the future. The current NIDAC team is rich with both deep experience, and talented, energetic youth.

In memoriam

David Nicholls

David Nicholls

Founder (1943-2022)

David founded NIDAC in 1966.

Having grown up with a fascination for electronics at the dawn of the age of the transistor, David saw the potential of this world-changing technology and its application to practical problems. David invented the doorway alarm at the age of 15.

This went on to become the “Nicholls Electronic Eye” and spawned numerous innovations in the field of electronics security, including the invention of the modern electronic siren, the early use of radar technology in security systems, the digital dialler, the secure Presco keypad protocol and false-alarm proof alarm control panels. David truly was the pioneer of the electronics security manufacturing industry in Australia and took a leading hand in developing security systems for domestic, commercial, industrial, aviation and government applications, as well as garnering several patents and Australian Design Awards.

Keen to keep NIDAC a family owned and operated business, David opened the door for Paula and Matthew to take the reins in 2018. David’s passion for innovation lives on in the modern incarnation of NIDAC, with the DN4 networked access control module named in his honour.

Sadly, David passed away in March 2022.

We’re a team full of drive and aspirations, and always looking for new people and opportunities in our field. If you want to be part of our story with us, through careers or partnership, reach out and contact us
