【摘要】 当家中的各种传感器发现意外情况时,监控前端节点进行视频采集,通过CC2430组建的家庭内部无线网络平台及时向主控平台发送视频信息;主控平台中断报警,并通过3G模块呼叫用户实现实时观察;主控平台视频信息异处备份,有效避免入侵者破坏信息。在系统平台上以不同的H.263编码质量测试表明使用高级质量选项对运动剧烈的画面更为有效;以不同速率测试表明,比特率越高则图像越清晰,但略有延迟,当画面运动较剧烈时,比特率越高接收图像越清晰;实现了安全可靠的远程实时3G无线视频监控系统。更多还原

【Abstract】 When a variety of sensors find the accident at home,the video capture on the monitor front-end node start work,the video information are sent to the host platform in time by the wireless network.The host platform is interrupted and alarming,and calling the owner to achieve real-time observation by 3G module.The video information of the host platform is backed up offsite,to avoid the intruder damage the information.The different H.263 encoding quality tests show that the dramatic motion picture is more effective with High quality option on the system.The different rates tests show that the image is more clear with the higher bit rate,but a slightly delay.When the picture is more intense motion,the higher bit rate enables that the picture is more clear.A secure remote real-time 3G-based wireless video surveillance is implementing.更多还原
