To ensure optimal performance, do not exceed the maximum number of cameras supported in Security Center 5.9 Unit Assistant Role (UAR) batch operations.
Some operations, like camera password change, introduces camera reconnection. It is recommended to plan these operations to occur during non-critical periods.
By default, the role runs on the server hosting the Directory and into Video Unit Control agents running on Archiver servers. It mainly uses CPU resources along with some network and disk resources.
The maximum number of cameras supported by each server type in Security Center 126.96.36.199 and later is as follows:
|Server Type||Recommended||High Performance|
|Directory & UAR||188.8.131.52
|Archiver & UAR Agents
|Same as maximum number of camera recommended for Archivers.||N/A|
