In a method for detecting an event occurred in a monitoring area, the method defines a reference characteristic parameter for a specific event, and stores the reference characteristic parameter in a storage device of the computing device. The method further obtains a voice stream of the specific event from an IP camera through a wireless network in real time, and extracts a characteristic parameter from the voice stream using a predefined algorithm. The method compares the extracted characteristic parameter with the reference characteristic parameter, and determines that the specific event occurs in the monitoring area if the extracted characteristic parameter accords with the reference characteristic parameter. |
