Abstract

The invention discloses a network camera device for using a single-chip processor and a single-chip wireless access system to realize video digit compression and wireless transmission. The inventive network camera device comprise a body, a video input device, and a voice input device, which can be wirelessly accessed into or independently accessed into wireless Ethernet and Bluetooth. The network camera uses a DSP processor as core, connected with a video AD converter, a voice AD converter, an interface circuit, a data memory SDRAM, a program memory FLASH, and a single-chip wireless access module. The interface circuit is connected with the voice AD converter. The video AD converter and voice AD converter are respectively arranged with a video input interface and a voice input interface. The single-chip wireless access module has a wireless access chip connected with an antenna module and a wireless interface circuit module. The DSP processor uses a real-time operation system RTOS, to complete video code and wireless transmission on the single-chip DSP processor.

Description

technical field [0001] The present invention relates to a video monitoring device with Bluetooth and wireless Ethernet connection functions, specifically a network camera device that utilizes a single-chip processor and a single-chip wireless access system to realize video digital compression and wireless transmission functions, wherein the wireless The transmission function supports bluetooth and wireless Ethernet at the same time, and belongs to the field of electronic equipment. Background technique [0002] With the use of digital remote monitoring systems more and more widely, network cameras based on wireless transmission are more and more appearing in monitoring places due to their convenience in installation and use, becoming an important type of video monitoring products. [0003] The main wireless transmission of existing wireless transmission network cameras is wireless Ethernet, which cannot be used in places without wireless access. Because Bluetooth has short-...
