摘要： An infrared intrusion detector uses infrared-sensitive sensors with pyroelectric sensor elements for detecting infrared radiation from a spatial region to be monitored. Infrared radiation passes through an entrance window and reaches the sensor elements via focusing mirrors. Extraneous radiation, outside the useful radiation band, is eliminated by filtering at the entrance window and by an optical transmission filter, and by scattering at suitable rough surfaces of the focusing mirrors. As a result, the infrared intrusion detector is less sensitive to extraneous radiation and less likely to produce false alarms.

摘要： A security system utilizes danger sensors (3) and a central unit connected wirelessly to the danger sensors (3). The danger sensors (3) have a communication module (8) which has the same dimensions and same shape for all sensor types, and which is intended to attach the danger sensor (3) to a mounting plate (2). In addition to the communication module (8), the danger sensor (3) contains a detection module (9) where the communication module (8) has a mechanical and electrical/electronic interface with the detection module (9).

摘要： In an infrared intrusion detector, a focusing mirror reflects incident infrared radiation of interest onto a pyroelectric sensor element. To prevent extraneous radiation from reaching the sensor element, the mirror has a reflective layer for reflecting infrared radiation of interest, and an absorptive layer disposed behind the reflective layer for absorbing extraneous radiation which has passed through the reflective layer. Infrared radiation of interest includes human body thermal radiation, and extraneous radiation includes the visible spectrum. Doped indium-tin oxide (ITO) is preferred for the reflective layer.
