To ensure optimal performance, don’t exceed the maximum number of video and access control units supported in Security Center 5.13 Unit Assistant role (UAR) batch operations.

Some operations, like password change and certificate updates for a camera or an access control unit, require the unit to be reconnected. Be sure to schedule these operations during non-critical periods.

IMPORTANT: Monitor the server CPU usage if normal usage is already high to ensure that UAR operation doesn’t introduce undesirable impacts.

The maximum number of units supported by each server type in Security Center 5.13 is as follows:
