The present invention is to provide an IP camera having repeater functions, which includes an image-capturing module for capturing images, an image processor for processing the images, a central processor including a network communication module for activating the repeater functions and mediating communication between a root wireless access point (WAP) and an external device, and an antenna electrically connected to the network communication module in order for the IP camera to make wireless connection to the root WAP, upload the images to the Internet and serve as a repeater between the two WAPs, and a memory configured for storing operating software, a plurality of service set identifiers (IDs) and an authentication key. Due to the repeater functions of the IP camera, the external device can identify the IP camera by the IDs and then connect to the Internet, even if the external device is outside coverage of a wireless LAN. |

1. An Internet protocol (IP) camera having repeater functions, the IP camera being provided in a network system comprising a root wireless access point (WAP), a terminal device, and at least an external device, the root WAP being connected to the Internet and configured for transmitting a wireless communication signal to form a wireless local area network (LAN), the IP camera and the terminal device being located within coverage of the wireless LAN, the IP camera comprising:
an image-capturing module comprising a lens set and an image sensor in order to capture an image; an image processor electrically connected to the image-capturing module in order to receive the image transmitted from the image sensor and perform a color-related process, a pixel-related process, and a compression process on the image; a central processor comprising a network communication module, the network communication module defining a mechanism for activating the repeater functions so that, when the mechanism is activated, the IP camera activates the repeater functions and can therefore mediate the communication signal and forward a packet between the root WAP and the external device, thereby eliminating dead zones in wireless communication therebetween; an antenna electrically connected to the network communication module in order for the IP camera to make wireless connection to the root WAP or the external device and thereby upload the captured image to the Internet or forward to the Internet a data packet transmitted from the external device; a network connection port connected to the network communication module in order for the IP camera to connect to the terminal device in a wired manner through the network connection port; and a memory for storing operating software, a first service set identifier (SSID), a first basic service set ID, an authentication key, and a second basic service set ID, wherein the first SSID serves to enable identification of the root WAP, the authentication key matches a private key in the root WAP, the first basic service set ID corresponds to a media access control address (MAC address) of the root WAP, and the second basic service set ID corresponds to a MAC address of the IP camera. |
