Subscribing to Events

You can create a local socket server to receive event messages by subscribing to events. Currently, event subscription is only supported in edge inference mode and not in in-cloud inference mode.

The subscription list displays all subscribers' information, including the subscriber name, number of subscribed video sources, number of subscribed events (sent and responded), creation time, and description. You can add, delete, modify, and search for subscriptions.

Adding a Subscription

  1. Choose Event Center > Event Subscriptions.
  2. Click Add Subscription and set parameters by referring to Table 1.
