Security monitoring arrangement and method using a common field of view

摘要

An integrated security arrangement comprising at least one battery-operated base unit that integrates a passive infrared (PIR) sensor 20 to detect infrared energy in a field of view; a data processor 30 to arm, in response to an intrusion signal from an intrusion sensor, motion sensing to detect motion from changes in infrared energy detected by the PIR sensor 20, and generate, in response to detecting motion, a movement indication; a camera configured to be armed, in response to a movement indication, to capture images in the field of view; and a wireless communication interface 15 to communicate the captured images; a control unit that includes a central processing unit (CPU) 55; and a wireless transceiver 60 to communicate with the base unit using the wireless communication interface 15 and to receive the captured images.
