Can cameras on the master domain VCN3000 be migrated to the newly added slave domain VCN3000 in batches?

You can add cameras one by one or in batches using a wizard or on the device management tab page. The VCN3000 supports cameras that comply with the HWSDK, HIKSDK, DHSDK, AXISSDK, ONVIF, TEYES, or GB/T 28181 protocol. For details about how to add cameras to the VCN3000, see the eSpace VCN3000 Product Documentation. Visit the Huawei Enterprise Technical Support website and download the eSpace VCN3000 Product Documentation of the required version.

If a VCN3000 connects to a third-party external domain, the VCN3000 can share only six devices with the third-party external domain. To share more than six devices, a license is required.

The VCN3000 supports the following connection protocols: ��GB/T 28181 ��GB/T 28181+ ��GB/T 669 For details about how to connect the VCN3000 to an external domain, see the VCN3000 Product Documentation. Visit the Huawei Enterprise Technical Support website and download the VCN3000 Product Documentation of the required version, for example, eSpace VCN3000 V100R002C00 Product Documentation.

Note: Here, V100R002C20 is used as an example. For other versions, see the product documentation. Maximum number of camera sequencing resources that can be added on the VCN3000: Each user can create a maximum of 32 camera sequencing resources. Each camera sequencing resource supports a maximum of 1024 cameras. A single camera sequencing plan supports a maximum of 16 camera sequencing resources. A single camera sequencing supports a maximum of 24 video panes. The camera sequencing interval ranges from 8s to 600s.

The VCN3000 platform sends a keepalive message to the external domain platform every 10s. If the VCN3000 platform does not receive a message returned by the external domain platform for three consecutive times, the VCN3000 platform regards the external domain platform as offline. After the external domain is offline, the VCN3000 stops sending video streams to the external domain.
