| Abstract: | A wireless video surveillance device was designed, based on the embedded processor $3C2410, the 2-way video encoder chip AT2042 and CDMA wireless data module. In order to realize real-time remote surveillance, the low-bit-rate compressed video streams of the scaled channel were transported to the monitor center via CDMA wireless data module. Simuhaneously, the high-bit-rate compressed video with high image quality, produced by the base channel, was recorded on the mobile hard disk or SD card and was suit for video analysis. Hardware structure and the key interface circuit of the wireless video surveillance device were presented. |
