Network Security Camera System and Its Application for Consumer Electronics Devices Supporting Machine-to-Machine Communications Platform

摘要

In this paper we present a network security camera system and its application to provide visual information for a machine-to-machine (M2M) communications platform. 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 charge-coupled device (CCD) image sensor, compress the image data size and transmit the compressed data to M2M communications platform via Internet. The processor is fabricated with 0.25 μm CMOS technology. The die area is 7800 × 7800μm~2 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 devices supporting an M2M communications platform, we applied the proposed system to a vacuum cleaner.
