Alerts & email

Alert rules

Settings → Alerts holds rules. Each rule watches one camera or node for a condition:

• Camera not reporting: the camera has stopped sending health reports.
• Node offline: the node has stopped checking in.
• Storage low: free space has dropped below a percentage.
• Object detected: AI detection saw a matching object.
• Speed over a limit: an object crossed a speed trap at or over a set speed.

Health rules are checked once a minute. The cooldown is the minimum time between repeat alerts, so a condition that stays true doesn't alert every minute.

Detection alerts

Object detected and Speed over a limit fire within seconds of the detection. Every filter is optional, and all the ones you set must match:

• Camera: one camera, or any camera.
• Category and label: for example Vehicle, or just trucks.
• Color: the object's color, or a person's shirt or pants color. See object colors.
• Zone: only objects standing inside one of the camera's zones (judged by the bottom of the box).
• Active: days of the week and a time window, in the server's time. A window like 22:00 to 06:00 runs overnight.

One detection alerts once. The cooldown applies to the whole rule, so on a rule watching any camera, a detection on one camera holds back the others until it ends.

Each rule can send to email, webhook, ntfy, Pushover, Slack, and Teams. Turn on a channel and fill in its fields.

Email

Email alerts are sent through the provider set up under Settings → Email. Save and send test checks the saved settings.

• SMTP: host, port, SSL/TLS, and credentials.
• Microsoft Graph: register an app in Entra ID, grant it the Mail.Send application permission (not delegated) with admin consent, and enter its tenant ID, client ID, and secret. There's no per-user sign-in.
• Gmail: create an OAuth client of type Web application in Google Cloud. Add https://<your-host>/Admin/OAuthCallback as an authorized redirect URI, and enable the https://mail.google.com/ scope. Then use Save and connect to Google once to grant consent.

Saved secrets are encrypted. If the server's data-protection keys are lost, re-enter them, and reconnect Gmail.
