Install wireless surveillance. Use the 5.8G wireless bridge. It's very reliable!
In recent years, the demand for wireless monitoring has become increasingly strong, which has led to a significant increase in the shipment of wireless bridges. The market has also become more demanding in terms of the technology of wireless bridges. Wireless monitoring is mostly used for remote unmanned monitoring. People attach great importance to the safety and stability of the equipment, as well as the normal working time and maintenance life. Guoqian Wireless Bridge has been deeply engaged in wireless security for many years and has developed cost-saving, simple and convenient engineering, and stable transmission wireless bridges!
如下:
无线网桥顾名思义就是抛弃了传统的铜线或光纤,利用无线通讯技术,以空气作为媒介进行网络数据传输,达到连接不同的网段的目的。
无线网桥根据频段可划分为2.4GHz和5.8GHz无线网桥,因工作频段的不同分别有各自的优势及特点!
5.8G无线频段是ISM开放使用的频段,它遵从IEEE.802.11a/n/ac标准协议,最新协议支持更宽的基带带宽,更高的传输速率,达到1Gbps甚至更高,而如今主流H.265/H.264编码方式让监控视频码流可降至200万像素2M的主码流,4K像素码流也可达到6M左右,所以5.8G频段的码流传输速率足够支持现有安防视频的传输。
1. 点对点传输,一端设置成客户端连接摄像头,另外一端设置成接收端连接NVR或者其它存储设备;
2. 点对多点传输,客户端连接摄像头,数据汇聚到中心基站设备;
3. 中继方式,5.8G无线网桥最好在无视距遮挡的范围内传输,一旦有遮挡或者传输距离上的问题,可以采用中继方式进行传输;
图钱无线网桥——
❤ 支持四大工作模式( AP \桥接/中继\路由) 灵活组网;
❤ 标准防水防雷等级,完美适应室外恶劣环境;
❤ 天线标准定向天线,大幅度增强信号收发能力;
❤ 安全性高,支持WPA/WPA2安全机制,全方位保护;
▲干扰更少,虽然无线网桥设备使用较为普遍,但还是以2.4G居多,5.8G的频段相对纯净,干扰较少,更能保证视频信号的传输效果,满足工程用户更大空间范围内接入无线互联网的需求,拓展无线局域网的应用空间,为室外工作环境中的互联网接入带来更大的便利
▲ 传输距离更远,在传输过程中,相比2.4G的无线网桥而言,衰减更小,适用于远距离传输
