When using the service for the first time, log on to the Content Moderation console to review the initial threat detection policy configuration.
Use case | Description |
You can adjust video detection policies based on industry practices or your business needs. You can adjust the following policies:
For example, to detect only high-risk violations and capture one snapshot every two seconds, you can adjust the detection rules in the console. | |
Set different threat detection policies for multiple business lines | If your business lines use the same service but require different threat detection policies, you can copy the service to create separate configurations.

By setting different threat detection policies for these three services, you can meet the needs of each business line. |
