<p>A monitoring system includes a sensor group, an image pickup apparatus and a server group. The sensor group has multiple sensors each of which corresponds to one of multiple events respectively, while, each of the sensors outputs corresponding sense signal to the image pickup apparatus respectively when the corresponding event occurs. The image pickup apparatus is used as a network connector, when the sensor group receives the sense signal, it picks up the instant video-audio information for a first preset time actively at the position which corresponds to the sensor outputting the sense signal and produces a video-audio information serial stream along with the video-audio information within a second preset time which is before the event occurring. Then, the video-audio information serial stream is sent to the server group via the internet.</p> |
