This paper presents a network security camera system and its application to provide visual information to consumer electronics devices in ubiquitous environment. For this system, we developed a network camera processor chip and a network security board. The processor includes a digital camera processor, a motion JPEG encoder, an Ethernet controller and an ARM processor, which serve to enhance the quality of raw images from a CCD image sensor, compress the image data size and transmit the compressed data via Internet. The processor was fabricated with 0.25um CMOS technology. The die area is 60.84 mm2 and the gate count is approximately 1.2 million. The network security board consists of the board driving the network camera processor chip and the CCD image sensor board. To demonstrate the applicability of the network security system to consumer electronics, we applied the proposed system to a vacuum cleaner.
