Alerts: The Inbox, Acknowledging, Sirens And Relays

When a camera sees something that needs attention, the box raises an alert. It appears in the dashboard’s inbox, is sent to the alert contacts on their channels, and can switch on a siren, a light or a relay. Repeats of the same alert on the same camera are counted on one alert, so the inbox stays readable.

Step 1: See That An Alert Is Open

Demo data.

1. The bell in the top bar shows how many alerts are open. Select it to open the inbox. The inbox is also in the menu under Monitor, Alerts.

Step 2: Read The Inbox

4. Select Acknowledge once someone has dealt with it.

Step 3: Acknowledge An Alert

1. Type a short note of what was done. It is kept in the audit log with your name.
2. Select Acknowledge. The alert leaves the open list; a new event on the same camera raises a new alert.

Demo data.

1. Set Show to the acknowledged alerts to see them.
2. Each one shows who acknowledged it and the note.

Step 4: Check Who Was Told

Open System, Deliveries to see every message the box sent, is still trying to send, or could not deliver.

Demo data.

1. A message that was not delivered, with the reason the mail server or WhatsApp gave. The box retries a message for 24 hours; select Try again to send it once more.

Step 5: Let Alerts Switch A Siren Or A Relay

Alerts can switch outputs on: Ethernet relay boards (Modbus TCP), HTTP relays and smart sirens, and the alarm outputs of ONVIF cameras. Open Manage, Sirens and relays, and select Add output. You need the role Admin of the site.

1. Give the output a name, for example “Siren, loading dock”.
2. Choose its type: a relay board (Modbus TCP), an HTTP relay or smart siren, or a camera alarm output (ONVIF).
3. Type the board’s address or name on your network, then its port, unit ID and relay (coil). Tick Wired normally closed if the relay is wired that way.
4. Tick the alerts that switch it on (none ticked: every kind).
5. Tick the cameras (none ticked: every camera of the site). Below them, choose the lowest severity that switches it.
6. Choose how long it stays on: a number of seconds, or until the alert is acknowledged.

Then select Save.

1. The output is listed with what switches it and its state.
2. Select Test to switch it on briefly and check the wiring. History shows when it was switched and why.

If the dashboard restarts, every output that should be off is switched off.
