Abstract: An image analysis system includes a plurality of cameras. The cameras are configured for taking images. The image analysis system further includes at least one server. The server includes a first obtaining module, a second obtaining module, a filter module, and a storage module. The first obtaining module is configured for obtaining the moving track of the target object. The second obtaining module is configured for obtaining the images taken by the cameras which the target object has passed according to the moving track. The filter module is configured for extracting images containing the target object from the obtained images according to pre-stored specific image features of the target object. The storage module is configured for storing the extracted images that contain the target object. An image analysis method and a server are also provided.

Abstract: A method for searching out an object in a building or group of buildings stores positions of objects in relation to wireless communication base stations. Relative lateral and vertical positions of an electronic device are calculated according to strengths of wireless signals received by the wireless communication base stations from the electronic device and by reference to sensors. Actual distance between the electronic device and the object is determined to be more or less than a preset distance and orientation is also determined. Information as to an object within the preset distance can be transmitted to the electronic device. A server executing the method is also disclosed.

Abstract: A system for monitoring abnormal behavior includes a distribution sensing unit and a controlling unit. The controlling unit is electrically connected to the distribution sensing unit. The distribution sensing unit is configured to sense a change of a temperature of a target object in the monitoring area according to a background temperature value and output distribution data of the temperature change. The controlling unit is configured to receive and analyze the distribution data of the temperature change to identify a behavior of the target object.
