Design Of Webcam With Environmental Information Detection Ability

The emergence of the webcam has greatly promoted the application of networked video surveillance.People's demand for networked video surveillance and intelligent network monitoring and control technologies has greatly increased.Current webcams,for example,lack the ability to detect environmental information and only one link of network access,poor reliability and other issues.Based on the analysis of the current application prospects and problems of networked cameras,this paper proposes a network camera solution with environment awareness and data link backup.The networked camera increases the ZigBee-based wireless sensor network.It realizes the function of environmental information sensing and device control in the monitoring area,implements backup of network transmission channels by adding phone modules,conducts in-depth research on network connectivity detection and handover technology,and completes network connectivity detection and handover algorithm.Design and implementation.The web-based camera not only has two access modes: Ethernet & mobile data network,but also introduces DTMF technology to enable users to detect and control remote scenarios through voice calls,in a timely manner for two days.If the network transmission links are not connected,the remote key information collection and acquisition can also be ensured.The application of highly reliable information detection and video surveillance applications can be applied.It has high engineering design reference value...
