Detector Technologies Limited (D-Tec)

D-Tec’s fire and smoke detection products are specified by name for worldwide applications.

D-Tec (part of the AD-Group) is acknowledged as the pioneer and world leader in the innovation of Video Smoke Detection (VSD) with over 14 years of experience in the field. Today D-Tec's fire and smoke detection products are specified by name for worldwide applications.

VSD is based on the computer analysis of video images provided by standard CCTV cameras. D-Tec's VSD automatically identifies the particular motion pattern of smoke and alerts the system operator to its presence in the shortest time possible. This enables a fast response to a potential fire, saving valuable time even in voluminous areas or where a high airflow may be present.

From its sales and distribution / support offices in Alton, Hampshire, D-Tec supplies VSD equipment to hundreds of customers either directly or via an ever growing network of European and worldwide distributors and its sales offices based in USA and Australia.
