When an incident is reported on Citizen, a notification is sent to users in the immediate area.
Notification distances are determined by population density and incident severity. If an incident appears to be escalating, there's a likeliness that public safety could be affected on a wider scale, or specialized units are called in, the notification distance increases.
A notification is also sent when a video is verified while live. When a live broadcast is verified, a notification is sent out 1 mile to New York City users and 2 miles to San Francisco users. (Read more about verified videos here.)
If you follow communities, you will receive notifications for escalating and/or confirmed incidents within the boundaries of a community you follow.
Finally, with Inner Circle, you can receive alerts when friends or family are near major crimes or active emergencies. (Read more about building your Inner Circle here.)
You can also receive alerts when someone in your Inner Circle broadcasts live on an incident.
