Central vs. Edge Storage architecture

Support for Edge Storage in IP video cameras enables a different type of video surveillance architecture than the traditional VMS architecture where recording servers are centrally placed. This means that there are now three main ways to store recorded video and audio:

• Centrally in the video surveillance system’s recording servers using a dedicated storage system

• At the edge of the surveillance system in the camera’s Edge Storage device

• As a combination of edge and central storage

Both central and Edge Storage architecture have their strengths and weaknesses when used exclusively, but in a combination, the architectures provide a more robust solution with higher performance and more flexibility in the VMS and network design. For example, the combination supports scenarios where cameras are not online all the time, such as cameras installed in trains, trams, busses or other vehicles.
