What Triggers Tesla Sentry Mode? Aware, Alarm and Intrusion Explained

Tesla’s Sentry Mode doesn’t react the same way to a passer-by and to someone trying to break in. It moves through a few clearly defined states, and only some of them put an alert on your phone. Here’s what triggers Sentry Mode, what each state means, and why a recorded event isn’t always a notification.

How Tesla Sentry Mode works: Standby, Aware and Alarm

When your Tesla is locked and in Park, Sentry Mode uses the external cameras and sensors to watch the area around the car. Based on what it detects, Tesla classifies the situation into one of three states:

• Standby — the default. Sentry Mode is monitoring but hasn’t detected anything it treats as a threat.
• Aware — Sentry Mode has detected a possible threat nearby (for example, someone leaning on the car). It can begin recording and show a message on the touchscreen.
• Alarm — Sentry Mode has detected a more severe threat (for example, a window being broken). It activates the car alarm, increases the center display brightness, plays music at high volume, and alerts the owner.

The key detail: Tesla decides which state applies, based on how it classifies the event. SentryAlert doesn’t change that classification — it reacts after Tesla reports the event.

What the Aware state means

The Aware state is Sentry Mode noticing that something is happening close to the car without treating it as a clear break-in. Tesla may begin recording footage (a USB drive or Dashcam storage is required to save clips) and display a message on the screen to deter the person.

Aware-state activity is often exactly the kind of thing owners care about — someone lingering by the door, a shopping cart drifting toward a panel, a neighbour’s door swinging open. But because Tesla may not classify it as a clear threat, it can be recorded without sending a push notification to the Tesla app.

What the Alarm state means

The Alarm state is Sentry Mode treating the situation as a real intrusion or impact — a window being broken, the car being forcibly moved, or a door or trunk-open attempt. In this state, Tesla:

• sounds the car alarm,
• brightens the center display and plays music loudly as a deterrent,
• and sends an alert that reaches the owner.

This is the clearest case: an Alarm-state event is the one most likely to reach your phone through the Tesla app.

What triggers a phone notification — and what is only recorded

A saved clip and a phone notification are two different things. Based on Tesla’s documentation, the Tesla app is notified mainly for clearer threats:

Sentry Mode situation	State	Phone notification?
Watching the area (locked, in Park)	Standby	No — monitoring
Someone lingers or leans on the car	Aware	Often recorded, not always notified
The alarm is triggered	Alarm	Yes
A door or trunk-open attempt	Alarm	Yes
Sudden, jerky movement (towing, shaking)	Alarm	Yes
Activity Tesla doesn’t rank as a clear threat	Aware	No — recorded, not alerted

So if your car saved a Sentry clip but your phone stayed quiet, the event most likely landed in the Aware state rather than Alarm. We cover that gap in detail in our guide on Tesla Sentry Mode notifications.

How SentryAlert helps after Tesla reports an event

SentryAlert is an independent companion app that adds a fast phone alert after Tesla reports Sentry activity. It connects through Tesla Fleet Telemetry using an approved connection and sends a push typically in under 1 second after Tesla reports activity — that timing is measured from Tesla’s report, not from the physical moment at the car. It doesn’t replace Tesla’s features, doesn’t give access to your camera footage, and isn’t affiliated with Tesla.
