To ensure optimal performance, do not exceed the maximum number of video and access control units supported in Security Center 5.11 Unit Assistant Role (UAR) batch operations.

Some operations, like password change and certificate updates for a camera or an access control unit, introduce unit 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.

IMPORTANT: Monitor server CPU usage if normal usage is already high to ensure UAR operation does not introduce undesirable impacts.

The maximum number of units supported by each server type in Security Center 5.9.1.0 and later is as follows:
