摘要： A security system includes a surveillance device that monitors a predetermined event and captures images in a monitor scene; and a controller that controls the surveillance device and transmits the captured images. The surveillance device adjusts image capture amount, image transmit amount, image transmit order or image resolution when the predetermined event is detected and an object is detected on the captured images.

摘要： An integrated fire alarm method includes receiving a preliminary detection signal from a preliminary detector, and comparing the preliminary detection signal with a predetermined corresponding threshold; controlling a notification device to issue an early-warning notification if the preliminary detection signal is greater than the corresponding threshold; receiving a primary detection signal from a primary detector after issuing the early-warning notification, and comparing the primary detection signal with predetermined corresponding threshold; and controlling the notification device to issue a formal notification if the primary detection signal is greater than the corresponding threshold.

摘要： A dynamic alarm priority system includes plural kinds of alarm devices, an alarm signal being generated when the alarm device is triggered; a plurality of image capture devices, correspondingly coupled to the alarm devices respectively, the triggered alarm device activating the corresponding image capture device to capture an alarm image; an interface device that receives the alarm signal; an assignment device coupled to receive the alarm signals, which are assigned priorities in order of time, thereby generating an initial alarm signal sequence; and an object detection device that performs object detection on the alarm image to determine whether an associated object is detected in the alarm image. The assignment device dynamically modifies the initial alarm signal sequence according to an object detection result from the object detection device, thereby generating an updated alarm signal sequence.
