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

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

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.
