# How alerts work > What a Fregata Mobile alert contains and when it arrives — the picture, the short video that replaces it, the wording, the actions under it, alerts that update in place, late and missed alerts, and what happens when your server can't be reached. An alert is a notification from your server that a camera saw something worth telling you about: by default a person or a car, as Frigate's own review settings decide. Fregata Mobile turns it into a notification with the picture, a short video, and words you can choose. _Picture: An iPhone Lock Screen with two alerts: Front Porch Alert, Person in Front Path Zone, with a description of the person and a picture, marked Time Sensitive; and Driveway Alert, Car in Driveway Zone, 12 minutes ago._ ## What's in an alert - **The title**: the camera, as **Front Porch Alert**. - **What was seen, and where**: **Person in Front Path Zone**. A recognised face or plate replaces the word it stands for, so **Alice in Front Path Zone**. - **A description**, when there is one: your server's GenAI description, or one written on this iPhone by [Apple Intelligence](https://mobile.fregata.app/docs/alerts/ai-descriptions/). - **The picture** the camera took, beside the words, and larger when you open the alert. - **Time Sensitive**, when [Break through Focus](https://mobile.fregata.app/docs/alerts/focus/) is on. All of the wording can be changed: see [Write your own alert wording](https://mobile.fregata.app/docs/alerts/wording/). Objects you've hidden in **Labels** are left out of it. ## What happens after it arrives An alert keeps improving for a little while after it first appears, without making another sound: 1. **The alert arrives**, at once, with the picture if it's ready. With **Alert first, then add the picture** on, it doesn't wait for a slow picture: the words come first, and the picture follows a moment later. 2. **The description is added**, once your server's GenAI or this iPhone has written one. 3. **The video replaces the picture** about 25 seconds later, with **Upgrade to video** on. The wait is because Frigate writes recordings in 10-second pieces, and a clip asked for any sooner comes back silently too short. If you dismiss the alert before the video arrives, it doesn't come back. Tap a delivered alert to open the camera's recording at that moment. ## Long-press an alert _Picture: An alert pressed and held: the picture with a play button, Front Porch Alert, Person in Front Path Zone and a description, and under it the actions Mute This Camera for an Hour and Never Notify for This…_ Press and hold an alert to see it larger, play its video, and use its actions: - **Mute This Camera for an Hour** [snoozes](https://mobile.fregata.app/docs/alerts/snooze/) that camera on this iPhone for an hour. - **Never Notify for This…** opens a short list of what the alert contained, such as **Person** and **Car**. Choose the ones you don't want to hear about from this camera, and tap **Stop These**. It changes your [notification filter](https://mobile.fregata.app/docs/alerts/filters/) in force, so you can undo it there. _Picture: The Never Notify sheet: Don't alert for these on Front Porch, with switches for Person and Car, and Stop These._ An alert that has anything else in it still arrives: with cars turned off, a car and a person together still alert, because of the person. ## Alerts from the same event Frigate updates an alert while the event is still going on: when the review ends, or when a GenAI description is ready. Fregata Mobile applies those to the alert you already have, silently, rather than sending you a second one. One event, one alert. ## When your iPhone was offline Alerts are counted. If your iPhone was off or out of signal and an alert never reached it, the next alert or the next time you open the app notices the gap. A notification says **Missed alerts: There were alerts while you were offline**, and the app shows a banner that opens your alerts in Review. It doesn't say how many. An alert that arrives a long while after it happened says so, under the words: **Delivered late. It happened at 2:14 PM, 3 hours ago.** ## When your server can't be reached Alerts don't need your iPhone to reach your server: they come through Apple's push service. The picture, the video and your own wording do, because they come from your server. So away from home without an [Away address](https://mobile.fregata.app/docs/getting-started/remote-access/), an alert still arrives, in Frigate's own words and without a picture. ## Grouping iOS stacks each server's alerts together in Notification Center. To see each alert separately instead, change **Notification Grouping** for Fregata Mobile in the iOS **Settings** app, under **Notifications**. ## Not getting alerts? Start with **Settings › Server Notification Setup**, which checks every step between your server and this iPhone. Then see [Alerts don't arrive](https://mobile.fregata.app/docs/troubleshooting/alerts/).
