Over 50 years on and stronger than ever – CIA’s history

The story of how Barrie and Janet Christie made the company the success it is today by commitment to the customer and investing in people and technology.

In 1970 Christie Intruder Alarms Ltd was established and the “crooked man” logo created which is so widely recognised today.  In 1971, we moved into our first office which was not much bigger than a cupboard.

In 1983, the company commissioned purpose-built offices in Waterlooville and in 1985, another office block was built on the site for sister company – Southern Monitoring Services Ltd – now one of the largest Alarm Receiving Centres (ARC) in the UK. Together, the two companies currently employ over 300 staff.

In 2010, Capital Security Systems, Gardner Security and State Digital Security, the three subsidiaries which had been acquired during the previous decade, were amalgamated with Christie Intruder Alarms Ltd.

In 2017, we were acquired by STANLEY Security part of the Stanley Black Decker Group.

We pride ourselves on providing an excellent customer experience with world-class product knowledge and technical expertise.

The company’s philosophy has always been forward-thinking and bold.  CIA prides itself on innovation, staying ahead of the current trends in technology, and places great emphasis on apprenticeship, training and staff development.
