Bracelet sensor


This rule serves a fundamental role in security applications, specifically involving personal bracelet trackers. Its primary purpose is to swiftly alert authorities or security personnel in case the bracelet is removed without authorization. In practical terms, this rule finds use in several security scenarios:

In legal contexts, such as house arrest or parole monitoring, where individuals are required to wear these bracelets, this rule ensures that any unauthorized removal immediately triggers an alert to the relevant authorities.

In high-security facilities, such as correctional institutions or secure research facilities, this rule can prevent unauthorized access or escape attempts. If a person under surveillance attempts to remove the bracelet, an immediate response can be initiated.

Furthermore, this rule can be applied in asset protection scenarios. High-value items or equipment can be tagged with these bracelets. If someone attempts to steal or tamper with the asset, security teams can respond swiftly.

In general, the rule provides a bracelet lock state, whether the bracelet has been locked or unlocked at some moment in time.


As this rule is based on hardware configurations, there is not much to configure in the rule itself.

Bind zone to rule:

Enables geofence rule binding.


Fill out the section if the rule needs to work only inside/outside of the selected geofences.

Map button:

Shows bound geofences on the map.


Emergency notification:

is used for important events. A message on the screen and the sound signal can only be disabled by clicking on the notification. Please note, some browsers can block notification sound until user activity is recorded on the page.

Push notifications:

Receive push notifications on the mobile app and web interface.

Add geofence name to the notification:

Adds names of the specified geofences to the notification text. This option is available only when the "Inside" geofence binding radio button is selected on the "Settings" tab.

SMS notifications:

List of recipients for SMS notifications when the event occurs.

Email notifications:

List of recipients for email notifications when the event occurs.


Set a schedule for when the rule will run. If your schedule indicates that the event should not run some day or time period, it will not appear as a notification in the user interface, and notifications via SMS or email will not be sent. Additionally, you can choose a default template for quick scheduling.

The platform specifics:

  • The "Bracelet sensor" alert has a 3-minute reset timer, meaning the alert event will not occur more often than once every 3 minutes. If this type of event occurs in time the rule has been waiting for the reset, this event will be omitted by the platform, including the reports.
  • In this rule type, users have the flexibility to select multiple trackers which they wish to receive notifications from. The only requirement is that the selected trackers must support Bracelet sensor events and the feature must be integrated on the platform for given trackers. This means that users can choose multiple compatible trackers to receive notifications from, allowing them to monitor harsh driving events across various vehicles or devices in a convenient way.
  • Whenever the platform identifies a hardware event of this type from a packet of tracker data with no valid coordinates in it, the platform counts the event as a valid one and displays it regardless of whether the event occurred within or outside the bound geofences. The logic of the Inside/Outside radio buttons is also ignored in this case. This behaviour is due to the fact that showing a controversial event once more is better than omitting it

Event reports

To view the dates when the events were received, you can build the "Report on all events" report.

The report represents the bracelet status at a moment in time:

  • Bracelet open
  • Bracelet closed
