How can I clone cameras of VCN3000?

Update the software for a linked clone VM group as follows: 1. On the FusionAccess portal, choose Desktop > VM Group. 2. Enter the search criteria for the target VM group and click Search. 3. In the VM group list, select the target VM group and click Update VM group software. 4. Set an update policy and notification message in the Select Update Policy window. If VMs in the VM group are in use or have important data to save later, select Next startup (Not now). If VMs in the VM group are not in use or have no important data to save, select Immediately (Forced update). 5. Click OK. 6. In Select Template to Be Updated, select the new VM template and click Finish.

After iCache is enabled on a VM, the system stores the frequently accessed data in iCache to increase the data access rate. The iCache configuration process is complex and the following is only a brief introduction: 1. Set an iCache value. The threshold is set during FusionCompute installation. You are advised to configure iCache and set its value to 12288 MB if you want to use linked clone VMs. 2. Enable the iCache function when you create the linked clone VM template. 3. Provision VMs using the template. The iCache function takes effect when you use the VMs. The iCache function can be disabled only after all VMs provisioned busing the template are deleted.

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.

Camera grounding includes video grounding and power grounding. Video grounding: Terminals such as DVR or matrix are used for indirect grounding. It is recommended that video grounding be completed on the local camera if videos are transferred through a video transfer device such as an optical transceiver. Power grounding: The ground terminals of the AC and DC power supplies need to be grounded when a centralized power supply mode is used, for example, switch-mode power supply (SMPS). Grounding standards: For the insulated copper-conductor cables used as ground cables as well as the power cables, their minimum cross-sectional area must be 6 square millimeters, minimum buried depth must be 0.5 m, and ground resistance must be smaller than 4 ohms.
