Does the platform support the integration of intelligent analysis for devices, and what methods can be used for the integration?
If the platform supports the integration of devices for intelligent analysis, when connecting NVR devices that support local intelligent analysis and channel device intelligent analysis, how should the protocols be connected?
For NVR devices that support both local intelligent analysis and channel device intelligent analysis, does the platform support two sets of alarms with the same topic?
Devices can in general send to different sorts of data to the XProtect recording server: Events and Metadata.
Metadata is a stream of data coming frequently perhaps for each picture frame, end Events are not that frequent but can be used to raise alarms or to trigger rules and similar.
If you look at the Demo Driver sample which is the sample showcasing the MIP Driver Framework you can see both events and metadata channel.
