There are three ways to run Milestone Interconnect. How to run your setup depends on your network connection, how to play back recordings, and whether you retrieve remote recordings and to what degree.
In the following, the three most likely setups are described:
Direct playback from remote sites (good network connections)
The most straightforward setup. The central site is continuously online with its remote sites and the central site users play back remote recordings directly from the remote sites. This requires use of the Play back recordings from remote system option.
Rule- or XProtect Smart Client-based retrieval of selected remote recording sequences from remote sites (periodically limited network connections)
Used when selected recording sequences (originating from remote sites) should be stored centrally to ensure independence from remote sites. Independence is crucial in case of network failure or network restrictions. You configure remote recordings retrieval settings on the Remote Retrieval tab.
Remote recordings retrieval can be started from the XProtect Smart Client when needed or a rule can be set up. In some scenarios, remote sites are online and in others, offline most of the time. This is often industry specific. For some industries it is common for the central site to be permanently online with its remote sites (for example a retail HQ (central site) and a number of shops (remote sites)). For other industries, like transportation, the remote sites are mobile (for example, busses, trains, ships, and so on) and can only establish network connection randomly. Should the network connection fail during a commenced remote recording retrieval, the job continues at next given opportunity.
If the system detects an automatic retrieval, or request for retrieval from the XProtect Smart Client, outside the time interval that you specified on the Remote Retrieval tab, it is accepted, but not started until the selected time interval is reached. New remote recording retrieval jobs will queue and start when the allowed time interval is reached. You can view pending remote recording retrieval jobs from System Dashboard -> Current Tasks.
After connection failure, missing remote recordings are by default retrieved from remote sites
Uses remote sites like a recording server uses the edge storage on a camera. Typically, remote sites are online with their central site, feeding it a live stream that the central site records. Should the network fail for some reason, the central site misses out on recording sequences. However, once the network is reestablished, the central site automatically retrieves remote recordings covering the down-period. This requires use of the Automatically retrieve remote recordings when connection is restored option on the Record tab for the camera.
You can mix any of the above solutions to fit your organizations special needs.
