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

Choose Event Center > Event Subscriptions.

Click Add Subscription and set parameters by referring to Table 1.

**Table 1** Parameters for subscribing to events
Parameter	Description
Subscriber	Enter a subscriber name.
Video Sources	Select All or Partial. All indicates that alarms of all video sources are subscribed to. Partial indicates that alarms of selected video sources are subscribed to.
Subscription Address	IP address of the subscriber's local PC, for example, http://127.0.0.1:8080.
Header	Headers are sent to the subscriber together with subscribed messages. The format is key-value. Set at least one custom header.
Subscriber Description	Description, which is optional.

After a subscription is added, the platform sends the events generated for the selected video sources to all subscribers who have subscribed to the video sources.
