Tesla Sentry Mode Not Recording: Settings, Triggers and Missing Clips
Start by separating an inactive Sentry Mode from an event that did not produce a saved clip. A missing phone notification, an empty event list and a USB error are different symptoms.
This guide focuses on parked security events. If driving footage also fails, begin with Dashcam not saving; if storage is not detected, use USB not working.
Match the Symptom
| What you observe | Next check |
|---|---|
| Sentry will not remain enabled | Inspect the power state and any message explaining why it turned off. |
| It works away from home but not near home or work | Review saved-location exclusions and the actual map location. |
| Driving clips save, but ordinary walk-bys do not | Review camera-based detection and event expectations below. |
| Phone alert appears, but there is no video | Verify the recording drive was connected and usable at the event time. |
| Clips play in the car but not on your computer | Check encryption and export; do not immediately format. |
| Both Dashcam and Sentry fail | Troubleshoot the shared recording setup before changing Sentry triggers. |
Keep a note of the location, event time and settings before changing them. Change one relevant setting at a time so you can tell what helped.
Confirm the Parked Settings
Check Controls > Safety > Sentry Mode or the equivalent menu shown by your software. Confirm Sentry is enabled for the current parking session, the car is locked and in Park, and Dashcam is enabled for USB recording.
Review Exclude Home, Exclude Work and Exclude Favorites. A saved location can cover the surrounding area, not just your driveway. Manual activation can override exclusions temporarily until the next drive.
With Camera-Based Detection disabled, the documented behavior is to save only for detected physical threats. An enabled setting still does not guarantee that every passer-by or impact will create an event. See Tesla's current Sentry Mode manual.
Do not strike, shake or attempt to break into the vehicle to test it. Observing that one walk-by produced no clip does not diagnose a failed camera.
Check Power Limits for Your Software
On vehicles with Low Power Mode, Sentry is unavailable while that mode is active. The current Model 3 manual allows an automatic threshold between 10% and 20%, with 20% as the default, under Controls > Charging > Low Power Mode. See Tesla's Low Power Mode instructions.
Older instructions describe a 20% battery cutoff. Do not assume the threshold is unchangeable on every version: follow the controls and alerts on your vehicle. Restore adequate charge and check the Sentry state again instead of relying on an earlier enabled setting.
A Notification Is Not Proof of a Saved Recording
Tesla documents that Sentry can issue a security alert without a recording drive, but video will not be available. Live Camera is also a separate feature: seeing the live view does not demonstrate that the USB drive saved a clip. Its app and Premium Connectivity requirements should not be confused with basic local recording. See Tesla's security support page.
Check saved events directly in the vehicle viewer while parked. Do not rely exclusively on phone notifications or previews when deciding whether a recording exists. App availability and controls depend on the vehicle and software.
Preserve Clips Before Storage Changes
Copy important recordings before cleanup or testing. If files are encrypted, they may need the recording vehicle or Tesla's authorized viewer rather than a regular video player. Use the missing Dashcam clips guide for locating and viewing them.
When both recording features report storage errors, follow the shared USB checks. If formatting is justified after backup, follow formatting instructions; formatting erases footage and cannot recover the missing event.
When to Request Service
Request help if Sentry repeatedly refuses to enable without an explained power or settings restriction, or if events consistently fail to save despite a working supported storage setup. Include the vehicle/software version, parking location, event time, battery state, detection settings and exact alert. Explain whether a manual Dashcam clip saves successfully.
A persistent black or missing camera view also deserves investigation. Preserve a sample, noting which view is affected. Do not clear camera calibration as a generic recording fix, open camera housings or disconnect vehicle power.
Sentry adds a security tool; it does not guarantee coverage of every event. Keep important clips in a separate verified backup and report missing recordings based on what you can observe.
