A video surveillance motherboard includes a core circuit and a surveillance circuit. The core circuit includes a processor, a main memory, a bus and a chipset. The chipset couples the processor to the main memory and includes a bus controller for controlling data transfer on the bus. The surveillance circuit includes a video connector, an audio connector, plural video capture controllers and a bridge. The video and audio connectors are configured to connect with a camera via image and audio transmission lines to receive image and audio signals from the camera. The video capture controllers are coupled to image signal input terminals of the video connector and audio signal input terminals of the audio connector. The bridge couples the video capture controllers to the bus and is configured to enable the video capture controllers to transfer data through the bus.
