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
Itinerary
• Factors affecting fire detection• Background to the Nature of Fire and how it develops• Cameras and Lens calculation• Positioning of cameras• Architecture of VSD and FireVu • Benefits of VSD & FireVu over conventional fire

Lets begin‘Video Smoke Detection’ first appeared on Tomorrow's
World programme back in 1997.
Factors Affecting Fire Detection
•Access
•Ex / Toxic Areas
•Acceptability of False Alarms
•Alarm Management
•Remote Signalling
•Detection Type
•Room Height
•Thermal Barriers
•Area of Coverage
•Internal/External
•Airflow Rate

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

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 FireVu
• 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

Future Developments
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.
