近年来,除传统的红外、高频调幅(315、433、915MHz)外,Zigbee、Z-Wave等新型短距离无线技术逐渐迈入商用,与此同时3G、4G传输技术不断推进,无线视频监控技术得到了较快的发展。无线监控由于具有组网灵活、部署方便、可扩展性好、维护方便、综合成本低等独特的优势,特别适合室外移动、距离较远及不方便敷设线缆的场景。目前无线视频监控在行业级市场,比如智能家居、环保监控、数字工地、森林、移动执法、公安警务通等方面的应用不断增多,市场份额日渐扩大。本文就无线视频监控在工地的应用做简单阐述。
In recent years, in addition to the traditional infrared, high-frequency amplitude modulation (315,433,915 MHz), Zigbee, Z-Wave and other new short-range wireless technology gradually into commercial use, while 3G, 4G transmission technology continues to advance, wireless video surveillance Technology has been rapid development. Due to its unique advantages of flexible networking, easy deployment, good scalability, convenient maintenance and low overall cost, wireless monitoring is particularly suitable for outdoor moving, long distance and inconvenient laying of cables. At present, the application of wireless video surveillance in the industry-level market, such as smart home, environmental monitoring, digital site, forest, mobile law enforcement, police policing and so on, is increasing and its market share is expanding. This article on the wireless video surveillance at the site to do a simple application.
