In a small workshop in Bolton in 1983, production of a small internal passive infrared (PIR) began.
Then came an external PIR which was housed in a modified car’s rear fog lamp plus a lighting control box. Distributors liked the products and in the following two years the increases in sales funded the development of single and two-zone security lighting controllers followed by a new external PIR and an expanded range of Minipassive internal PIRs.
GJD showed off its new product range at IFSEC. In 1990 GJD introduced a new lens for the GJD Minipassive – this was a departure from the traditional Fresnel lens by giving multiple vertical curtains.
The priority in the early and mid 1990s was the need to supply external PIRs for the blossoming CCTV market and to meet this demand, the Elite PIR was launched. By 2001 GJD had developed their first wireless system – the Opal RFX and receiver.
For many years, research and development costs had been escalating at an alarming rate and as a consequence many British companies were struggling to keep pace with their rivals in the Far East, who often had far more support from their financial and government institutions.
In December 2004 Mark Tibbenham acquired passive infrared (PIR) company GJD. Mark recently said: "The decision at the time was a total no brainer. With the massive growth in CCTV and security systems in both the commercial and domestic sectors, the potential for GJD to regain its former position as a market leader, if not the market leader, was there for all to see. I am so pleased to be able to announce that once more a British company is leading the world in external PIRs, CCTV triggers and external lighting control systems and is going from success to success after 25 years." As Managing Director, he brought more than 20 new products into the market, including the D-TECT external presence detectors. Pictured is the D-TECTX external wireless system (PIR, receiver and walk tester) with a communication range of up to 500m, launched last year. Multiple launches are planned for 2008, which started with the Mini Opal in January, to be followed by a new Video Gateway and the D-View.
The first D-TECT prototype saw the light of day at IFSEC 2005 – followed by D-TECT2 in October 2005. D-TECT3 appeared in March 2006 and the Dygizone lighting controller in May 2006. The year 2007 with the launch of D-TECT1 in April (for the export market only) and the D-TECTX external wireless system (PIR, receiver and walk tester) with a communication range of up to 500m. Multiple launches are planned for 2008, which started with the Mini Opal in January, to be followed by a new Video Gateway and the D-View later.
