Streaming capability is used to monitor the production line remotely. Under normal operation, this is enough for the human operators to get an overview of the line while it is working. For this purpose, a simple low-frame-rate video stream (25 fps or something) over a local area network does the job.
The most interesting functionality is related to recording capability, however. As shown in the previous image, the production line is governed by a Programmable Logic Controller (PLC), which is interfaced to several actuators and sensors. The Of course, the line is may also be subject to different kinds of faults. The most severe—for instance, a major mechanical failure—may lead to the automatic stop of the line. Thanks to the aforementioned sensors, the PLC is aware of such faulty conditions. In the occurrence of these events, it raises an alarm signal directed to the video recording system. ThisWhenever an alarm is detected, the recording system's aim is to store on a mass storage device high-frame-rate footage showing what happened right before and right after the alarm event. ===Alarm mode===During normal operation, the high-frame-rate stream (indicated by the red flow in turn, the previous picture) is stored
which, in turn, enters "alarm mode. this device would be " This mode is used to shoot a particular portion of the line for:
The typical scenario in which this device would be used Under normal conditions, this camera streams
