Abstract: A camera with a built-in license plate recognition function includes a license plate information base, a general purpose input/output (GPIO) port, an image-capturing module, a license plate image processor, a communication module, an audio-capturing module, and a processor. In the camera, the image-capturing module captures a license plate image when determining a vehicle enters/exits from a vehicle access control site; next, the license plate image processor segments and recognizes the image with a conventional image processing technique and compares the image with that in the license plate information base; and then the GPIO port controls the entrance/exit of the vehicle through a collapsible door, a sensor, and an alarm. Furthermore, remote control software may be installed on an external equipment, and the external equipment is connected to the communication module in a wired/wireless manner for achieving remote monitoring.

Abstract: A network audio/video (AV) rescue system is provided, which includes more then one rescue terminals, and each rescue terminal transmits signals with a server through a same protocol. When a rescue terminal is activated by a local user, image and audio signals can be transmitted for calling a rescue. A server can immediately receive the image and audio signals and determine the network address of the rescue terminal sending the signals. Therefore, a remote user on the server end can communicate with the local user through the server, such that the remote user can know what is needed for the local user and to provide necessary help and assistance to the local user.
