Vehicle monitoring Show limitless charm in security engineering
In the field of video data transmission security industry, cable video data transmission technology meet the high-definition video data transmission at the present have no problem. But in the front and back products in the security industry and codec compression technology. therefore, the development of video data transmission technology of cable in recent years is relatively slow.
And then in the current wireless video data transmission, what are the wireless technologies used in the field of vehicle monitoring? One is video, video and pictures for vehicle monitoring(like Vehicle DVR).the other is wireless transmission technology for vehicle to provide satellite positioning.Besides these,there are also some wireless technology in vehicle security monitoring system include bluetooth microwave and other technologies.but these technologies are relatively less used in vehicle monitoring.
Next, 4G technology is gradually spreading.It integrates 3G technology and WLAN to achieve fast transmission of audio, video and image data. Compared with 3G, 4G has increased exponentially in uplink and downlink rates.Mobile DVR with 4g has also provided in Richmor.
At present, the application of WiFi technology has been quite wide.3G, WI-FI and 4G, in the video data transmission point, does not need to experience the forwarding process an intermediate device, can direct data transmission between two points, 3G and 4G in data transmission is achieved through the adapter and a base transceiver station, but we need to explain when the WI-FI is, through the hot to realize the connection of wide area network, the point-to-point data transfer advantage has all gone, but still WI-FI advantage in data transmission speeds, relative 4G maximum downlink rate were 150Mbps (FDD-LTE standard) and 50Mbps (TD-LTE standard) for on the downside, WI-FI wireless transmission speed can be up to 300Mbps, the speed advantage is quite obvious.

In early, the most widely used wireless transmission technologies on vehicle video surveillance are 3G (CDMA2000, WCDMA, TD-SCDMA), 4G (TD-LTE and FDD-LTE) and WI-FI.Richmor is a HD Car DVR wholesales china,their company provided many kinds of mobile DVR with WIFI.You can click the net to get more information.
Wireless video transmission technology before 2008 is still in 2G GSM and CDMA 1X era, due to the speed of wireless transmission is too slow, it can only transfer low resolution images in most cases; until 2008 began to transport vehicle wireless video using 3G network, but in the actual process of wireless video transmission in the wireless base station interface bandwidth, the effect of real-time transmission of the image is often far from the customers’ demand.
