# UniFi Protect glass break heard notifications on your phone

> Get a Highest-priority push notification when a UniFi Protect camera hears glass breaking, with a button to open the event clip.

- Company: UniFi Protect (https://www.justpush.io/recipes/unifi)
- Event: `alrmGlassBreak` (Glass Break)
- Tags: Smart home, Security
- Install: https://studio.justpush.io/recipes/unifi/glass-break
- Web page: https://www.justpush.io/recipes/unifi/glass-break

## Setup

1. Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
2. In UniFi Protect, go to Settings > Alarm Manager and click Add Alarm.
3. Set the trigger to Glass Break and select the camera(s) it should watch.
4. Under actions, add a Webhook with method POST and paste your webhook URL (shown in Studio after install)?tz=Europe/Amsterdam as the URL, using your own time zone.
5. Save the alarm, then press Test to send a sample event.
6. Add your time zone to the webhook URL so the notification shows the local time:
7. ```
8. your webhook URL (shown in Studio after install)?tz=Europe/Amsterdam
9. ```
10. Use your own [time zone name](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones). UniFi only sends a UTC timestamp; without `tz`, the time is left out of the message.
11. Alarm Manager sends every alarm to the same webhook shape. This recipe only reacts when the alarm contains a glass break trigger, so it stays quiet if you point other alarms at the same integration.
12. Give the alarm a descriptive name, like "Living Room Glass". The payload only identifies the camera by its MAC address, so the alarm name is what tells you where it happened.
13. The **View clip** button uses `eventLocalLink`, which only resolves on your home network (and shows a certificate warning). Away from home it won't load.

## Code

Studio calls `handleRequest(request)` with the incoming webhook (`{ method, headers, body, query, raw }`) and sends the message object it returns. Returning `null` sends nothing.

```js
// UniFi Protect → glass break heard
// Fires when a UniFi Protect camera's audio detection hears glass breaking.
//
// Set this up as an Alarm Manager alarm in UniFi Protect with the "Glass Break"
// audio trigger and a Webhook action pointing at your JustPush Studio integration URL.

// UniFi only sends a UTC timestamp, not your console's time zone, so the time zone comes
// from the webhook URL: ?tz=Europe/Amsterdam. Without one (or with an unknown name) the
// time is left out rather than shown in the server's time zone.
function localTime(timestamp, request) {
    const timeZone = typeof request.query?.tz === "string" ? request.query.tz.trim() : ""

    if (!timestamp || !timeZone) return null

    try {
        return new Date(timestamp).toLocaleTimeString("en-GB", { hour: "2-digit", minute: "2-digit", timeZone })
    } catch {
        return null // not a time zone name this runtime knows
    }
}

function handleRequest(request) {
    const alarm = (request.body || {}).alarm

    // Guard: ignore anything that isn't a UniFi Protect alarm payload.
    if (!alarm || !Array.isArray(alarm.triggers)) {
        console.log("Not a UniFi Protect alarm payload — skipping")
        return null
    }

    // Alarm Manager sends every alarm to the same webhook, so only handle glass breaks.
    const glass = alarm.triggers.find((trigger) => trigger?.key === "alrmGlassBreak")

    if (!glass) {
        console.log(`Ignoring "${alarm.name ?? "unknown"}" alarm — no glass break trigger`)
        return null
    }

    const heardAt = localTime(glass.timestamp, request)

    // The payload only carries the camera's MAC, so the alarm name is the most
    // readable hint of where this happened (e.g. "Living Room Glass").
    const where = alarm.name ? ` — ${alarm.name}` : ""

    // The local link only resolves on your LAN, and only when the event was recorded.
    const eventLink = alarm.eventLocalLink

    return {
        title: "💥 Glass break detected",
        message: (heardAt ? `Breaking glass heard at ${heardAt}` : "A camera heard breaking glass") + where,
        topic: "UniFi Protect",
        priority: 2, // Highest — possible break-in happening right now
        // sound: "siren", // any of Studio's sounds, e.g. incoming, bugle, siren
        buttons: eventLink ? [{ cta: "View clip", url: eventLink }] : [],
    }
}
```
