Match the following IVS1800 networks with their features:

Correct Answer:

Explanation:
* Cloud service network # The IVS1800 connects to the HUAWEI CLOUD service platform over the Internet and allows you to manage devices on the mobile app.
* Network for connecting the device to the upper-level video and image management platform # The IVS1800 connects to the IVS3800 platform as an NVR.
* Multi-node network # You can manage multiple IVS1800s on the iClient.
* Single-node network # The IVS1800 can connect directly to a monitor, using an HDMI cable, to display live or recorded video.
The matching is based on the deployment role of each IVS1800 network type. The cloud service network is the mode used when the IVS1800 connects outward through the Internet to Huawei cloud services for remote device management, so it matches the feature about connection to the HUAWEI CLOUD service platform and mobile-app management. The network for connecting the device to the upper-level video and image management platform is the upstream integration path used when the IVS1800 works under a larger platform such as the IVS3800 , so that feature matches the statement about connecting to the IVS3800 platform as an NVR .
The multi-node network is intended for centralized management of multiple IVS1800 devices, which is why it matches the feature stating that multiple IVS1800s can be managed on the iClient . The single-node network is the standalone deployment model, so it matches the feature where the IVS1800 connects directly to a monitor through HDMI for local live or playback display. This mapping follows the standard Huawei deployment logic of standalone, clustered, upstream-integrated, and cloud-managed operation.
