Glass break heard
Get a Highest-priority push notification when a UniFi Protect camera hears glass breaking, with a button to open the event clip.
Three steps to your first push
STEP 01
Install the recipe
One click in Studio gives you a personal webhook URL.
STEP 02
Paste your URL into UniFi Protect
Add it as a webhook for Glass Break.
STEP 03
Get a push on your phone
With the text, sound and buttons from the recipe.
How to set up the UniFi Protect glass break webhook
- Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
- In UniFi Protect, go to Settings > Alarm Manager and click Add Alarm.
- Set the trigger to Glass Break and select the camera(s) it should watch.
- Under actions, add a Webhook with method POST and paste your webhook URL?tz=Europe/Amsterdam as the URL, using your own time zone.https://••••••••/•••••••• your personal URL, shown after install
- Save the alarm, then press Test to send a sample event.
- Add your time zone to the webhook URL so the notification shows the local time:
- ```
- your webhook URL?tz=Europe/Amsterdam
- ```
- 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.
- 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.
- 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.
- 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.
What runs when the webhook arrives
Studio calls handleRequest(request) with the incoming webhook and sends the message it returns. It's yours after install; change anything.
