Abstract: An electronic system with router and charger functions and a method for operating router and charger functions are disclosed. The electronic system connects to an electronic device and includes a router module, a charger module, and a connection interface. In which, the router module has a processing unit and a communication unit, and the charger module has a rechargeable battery. The processing unit and the communication unit may provide data routing capabilities so that the connected electronic device can share the Internet resources to other devices. At the same time, the rechargeable battery of the electronic system may provide electric power to the electronic device for charging the battery within.

Abstract: A communication system and a method adapted in the communication system for monitoring and remote debugging are provided. The communication system comprises a server, at least one terminal device and a customer service team end. The terminal device is to generate a terminal device data, wherein the terminal device further sends the terminal device data either unsolicitedly or on demand to the server, wherein the data processor further generates report files according to the terminal device data. The customer service team end is to retrieve the terminal device data and the report file from the server for to monitoring and remote debugging.

Abstract: A system for remote monitoring and surveillance is disclosed in this invention. The system comprises a plurality of cameras, a router, and a server. The cameras are connected with the router separately through a wired or wireless communication protocol. The router is connected with the server through a wireless communication protocol. The cameras capture scenes and convert the captured scenes into a plurality of image signals. The router uses a communication protocol to connect with the cameras, and the router transmits the image signals by a first wireless communication protocol. The server receives the image signals by the first wireless communication protocol, processes the image signals to obtain first images, and displays the first images. A method for remote monitoring and surveillance is also disclosed in this invention.
