Our Team


Gerard Curtin, Managing Director – Gerard Curtin is the founder and Managing Director of National Electronic Security, formed in 1989 as Security Connections after a successful NSW Police Force career.

The knowledge acquired during time as a police officer would form the basis for NES. Gerard’s common sense approach to policing meant being hand selected for the elite Anti Theft Squad, and serving as the youngest NSW plain-clothes officer. This focus on all aspects of theft allowed Gerard to hone his gift for electronic alarms and surveillance, often providing advice and guidance to businesses and the community affected by theft.

Initially a sole trader Gerard would door knock, toolbox in hand, offering his security services. Business took off (with a little help from a large and supportive family and their contacts), and by 1992 clients included Qantas, Australian Airlines and Central Sydney Area Health, plus advising the NRMA on burglar alarm requirements.

Joined by wife Lisa in 1995 the company has grown ever since. With a focus on attention to detail and strong ethics, instilled by his prominent Sydney architect father Kevin Curtin, clients have come to recognise the reputable services of NES.

Today when Gerard is not managing the business, he is known to occasionally pull the overalls on, still maintaining his security technician license.

greg-waresGreg Wares, Sales Manager (LSC.No. 408608706) – Greg brings extensive security systems knowledge grounded in 10 years of NSW Police experience and service, including tenures in General Duties, State Protection Group, prisoner custody and transport.

As a licensed security consultant and technician Greg continually maintains his knowledge to ensure our products and installation processes are to industry best practices and, importantly, meet National Electronic Security’s own high standards.

Having formalised security standards and procedures for major financial institutions, large industrial sites, high density, multi user office complexes, business operations premises and residential homes Greg is well regarded in the industry.

Whether working with a property developer, company CEO or homeowner, Greg believes every person he deals with deserves nothing less than his total commitment.
