, you only need to log on to the video server over the network to view the monitoring images. Because of the TCP/IP architecture, the video server is very convenient to use. Any monitoring site only needs an IP address and can be configured with a fixed IP address to install the video server.
A standard video server also requires RS232, rs422, or RS485 control interfaces and level input/output interfaces. The serial port can be used to conveniently implement remote control of cameras, cloud plat

As we all know, data is the blood of GIS. The most important thing about a GIS system is data, and the cost of the whole system construction process is relatively large. To this end, many GIs manufacturers and database manufacturers have gradually launched storage solutions for spatial data.
Among them, Oracle Spatial is a new generation of spatial database launched by Oracle, the largest database vendor at present. It uses the object relational data storage mode to store spatial data.
