How do we detect if a camera is offline and reflect on dashboard ?
- Every camera sends a heartbeat every 10s.
- If the camera has not sent a heartbeat in 5min or more, the camera is considered offline
- If a customer does not see the camera go offline after 5min, it is because we do not push updates to the dashboard. It will require them to refresh the page.
How do camera offline alerts work?
- Every minute, we scan cameras and look at the timestamp of their last heartbeat. if the time elapsed since the last successful heartbeat is greater than the threshold, we send a camera disconnect alert. In theory, the maximum time a camera could be off before a disconnect alert is 11 minutes.
