Detector Technologies Ltd

Detector Technologies Ltd • D-Tec was created from two companies, Intelligent Security and AD Holdings (Dedicated Micros) with the sole purpose to further market and develop the technology of detecting fires through the use of CCTV cameras • The technology foundation for Video Smoke Detection was created back in 1996 and the product is continually being refined and enhanced. • From being the pioneers of Video Smoke Detection we have continued to be the World market leaders with continual design and development • D-Tec is a small ‘High Tech’company yet international with distribution networks in Australasia, USA, Africa, Middle and Far East as well as Europe

Lets begin ‘Video Smoke Detection’ first appeared on Tomorrow's World programme back in 1997.

Factors Affecting Fire Detection • Detection Type • Access • Room Height • Ex / Toxic Areas • Thermal Barriers • Acceptability of False Alarms • Area of Coverage • Internal/External • Airflow Rate • Alarm Management • Remote Signalling

Three Dimensional Thinking • Camera can detect anywhere in the field of view • Lens designates the viewing area

Lens Calculation Methodology • The web makes this task simple • The wider angle the lens the smaller objects appear in the distance

Images demonstrate different camera lenses -The wider the lens angle the smaller objects appear in the distance

Positioning Cameras Effectively

Benefits of VSD over Conventional Fire Detection • Detection at Source • Visual Verification • Large Area of Detection • Zoning • Ability to “Look” in • Use of Existing Cameras • DETECTS WHERE NOTHING ELSE IS SUITABLE

Benefits of Fire. Vu • Remote monitoring • Visual Memory File • Pre and post alarm video clips • On line diagnostics • On line maintenance / testing • Software Based System • System data management • DETECTS WHERE NOTHING ELSE IS SUITABLE

Typical Applications • Historic Buildings • High Value Areas • Power Generation Halls • Telecommunications • Large Open Areas • Production areas • Warehouses • Aircraft Hangers • Atria • Shopping Centres • Tunnels • Transportation • Cold-stores • External

Approvals & Awards

Future Developments • Flame • Central Station • Pan Tilt Zoom (PTZ) • Fish-Eye Lens • 360° • Web Enabled Camera • Gas

Summary • Offers many advantages over and above other detection devices • Offers detection in environments considered impractical or impossible • Shares CCTV Systems thus can offer cost savings. • Flexibility within the software to allow ‘engineered solution’ and ultimately reduce spurious alarm activations.
