|Format||Member Price||Non-Member Price|
The rapidly expanding market for pyroelectric detectors in passive infra-red intruder alarms does not call for high performance detectors in the conventional sense, but nevertheless places requirements on the detector which are very demanding in terms of consistency of product and long term reliability. This paper examines some of the areas of interaction between the system requirement and the detector design and highlights the parameters of importance and the ways in which these are achieved in a large volume production environment. Future market trends and the impact on detector design are also discussed.
