Hello.

For DR configuration, refer to the corresponding guide:

After a DR relationship is established between two domains, the production domain will synchronize cameras to the DR domain. That is, cameras in the production domain will be connected to the DR domain, which occupies the connection resources of the DR domain. Therefore, when calculating the specification of the DR domain, ensure that the following requirements are met:

* Maximum number of cameras connected to the DR domain ≥ Number of cameras connected to the DR domain + Total number of cameras connected to all production domains For example, in the active backup N+1 scenario, if 1000 cameras are connected to N production domains and 100 cameras are connected to one DR domain, the maximum number of cameras that can be connected to the DR domain must be greater than 1100.

*If recording is required in the DR domain, the specification needs to be calculated based on connected MPURs instead of MPUTs.
