Tesla Sentry Mode: What It Is, How to Use It and Battery Drain

Tesla's Sentry Mode captures videos from up to four cameras at once

Not a Tesla App

Tesla Sentry Mode is an intelligent vehicle security system designed to monitor and record potential threats around your parked Tesla. This feature utilizes the vehicle's cameras and sensors to detect suspicious activity, notify the owner through the Tesla mobile app, and save footage to a USB drive.

What is Sentry Mode

When enabled, Tesla Sentry Mode keeps the vehicle's cameras and computer powered on and ready to record potential threats while the car is locked and in Park. If a threat is detected, the system pulses the headlights, displays a message on the touchscreen, and may sound the alarm, depending on the situation. In addition, footage of the event is saved to a USB drive, and the owner will be notified via the app if the alarm goes off. Sentry Mode offers an extra layer of security for Tesla owners, helping to deter would-be thieves or vandals.

Cameras and Sound

While Sentry Mode is enabled, it will record from four of the vehicle's nine available cameras. The video recorded comes from one of the front-facing cameras, the fender camera on either side of the vehicle, and the rear camera. The other remaining front-facing cameras, B-pillar cameras, and the cabin camera do not record at this time.

Teslas do not contain any external microphones, so all Sentry Mode videos are silent. Although Teslas do contain internal microphones, Tesla does not capture audio from these microphones. In fact, even if you're viewing the interior camera in the Tesla app, you can not hear any audio from inside of the vehicle.

How to Turn On Sentry Mode

You can enable Sentry Mode by tapping Controls then tapping 'Sentry.' The Sentry Mode icon will turn red when Sentry Mode is enabled. You can also choose to turn on Sentry Mode automatically when the vehicle is parked or activate it using the Tesla mobile app. Voice commands like "Keep Tesla safe," "Keep my car safe," "Sentry on," or "Enable Sentry" can also be used to enable the feature.

Enable Sentry Mode from the Controls menu

How Long Does Sentry Mode Stay On

Once Sentry Mode is enabled, it will remain on until you turn it off, or when your battery reaches 20%. If the battery falls below this level, Sentry Mode will turn off, and you will receive a notification via the Tesla app. Since Sentry Mode increases power consumption, Tesla turns it off automatically to leave you with enough energy to reach your destination.

Sentry Mode Battery Drain

Since your vehicle's computer needs to remain on to process video from its various cameras, there is additional power usage while Sentry Mode is enabled.

The actual amount of power consumed varies based on your vehicle's specific hardware, but tests have shown that the vehicle will consume about 250 to 300 watts while Sentry Mode is on. This is equivalent to losing about 1 mile of range for every hour Sentry Mode is enabled.

In a day, Sentry Mode may consume as much as 7.2 kWh, about 24 miles of range, or roughly equivalent to 7% to 14% of your battery, depending on your model and battery size.

Since Sentry Mode consumes so much energy, it's best to use it only when needed. Sentry Mode is not meant for when your vehicle will be parked long term, as it'll quickly drain your battery. Luckily, Tesla offers options to automatically enable Sentry Mode at specific locations and Sentry Mode is automatically disabled when the vehicle's battery falls to 20%.

Sentry Mode Options

You can customize Sentry Mode settings to fit your preferences and requirements. Some options available include:

Disabling sounds: If you want to silence the security alarm and audio system when the alarm is triggered, navigate to Controls > Safety > Disable Sentry Sounds. Sentry Mode will still send a notification through the mobile app and save the last 10 minutes of footage of any events that occurred.

Excluding specific locations: In Controls > Safety > Sentry Mode, you can choose not to enable Sentry Mode in particular areas, such as your home, work, or favorite destinations. This can be helpful if you want to conserve battery power or avoid unnecessary recordings in familiar areas.

Choosing the clip length: In some markets (Not available in the U.S. and Canada), you can select the length of Sentry Mode video clips, allowing you to customize how much footage is saved during an event. 

Disabling camera detection: If you prefer, you can disable camera detection so that Sentry Mode only activates when the car senses a physical intrusion. This can be helpful in situations where you want to minimize the number of false alarms or unnecessary recordings.

How to Set Up Sentry Mode

First, insert a compatible USB drive into the glove box USB port. If your car doesn't have a USB port in the glove box, you can use one in the center console. Note that not all Teslas have data-capable USB ports in the center console, so the glove box should be your first choice. Chances are that Tesla already included a compatible USB drive in the car for you. Tesla defines a compatible USB drive as one that is USB 2.0 compatible and holds at least 64 GB. This Samsung USB drive is a good choice for Sentry Mode because of its durability and size. It offers fast write speeds and 256GB of storage, 4x Tesla's recommendation.

Next, you can format the USB drive by going to Controls > Safety and tap on "Format USB Drive." Tesla recommends using a high-quality USB drive to ensure smooth recording and playback of Sentry Mode videos. You can also enable Dashcam recording. Navigate to Controls > Safety > Dashcam in your vehicle's menu and set it to Auto. This will allow your vehicle to automatically record footage while driving. Footage will automatically be recorded when an event is detected or when you tap the Dashcam icon under Controls > Dashcam.

How to View Sentry Mode Recordings

You can review your Sentry Mode video with the Dashcam Viewer app in the car

Not a Tesla App

To view Sentry Mode or Dashcam videos, use the Dashcam app in your vehicle. The Tesla system tags events with a red dot, making locating and reviewing footage easier. This feature allows you to quickly identify any incidents around your vehicle and gather evidence if necessary. Remember to regularly check your USB drive's storage capacity, as new recordings will overwrite the oldest ones when the drive is full. It's a good idea to back up important footage to a separate storage device for safekeeping.

Sentry Mode Live Access

You can view live footage from your vehicle in the Tesla app

Not a Tesla App

Sentry Mode Live Access lets you view your vehicle's cameras in real-time using the Tesla mobile app. This feature requires Tesla's Premium Connectivity. When using View Live Camera, your vehicle will periodically flash its exterior lights and displays a message on the touchscreen, notifying others that the area surrounding the vehicle is being viewed through the cameras.

To enable the View Live Camera feature, touch Controls > Safety > Sentry Mode > View Live Camera via Mobile App on the car's touchscreen. First, ensure no occupants are in the vehicle, and all doors are locked. Then, navigate to Safety > Sentry Mode > View Live Camera in the Tesla app. The live camera feed is fully encrypted and cannot be accessed by Tesla, ensuring your privacy. View Live Camera is limited to approximately one hour (or 15 minutes for some regions) of cumulative usage per day. Although Sentry Mode Live Access is widely available, it is not currently available in all markets.

If your vehicle is equipped with a pedestrian warning speaker you can press and hold the microphone button in the app to transmit your voice through the speaker, potentially deterring would-be intruders or vandals.

When Dog Mode or Sentry Mode are enabled, you can also switch the live camera view to see through the vehicle's interior camera. This can be useful if you want to check on your pet while away from the vehicle. Note that this feature is not supported in vehicles with Autopilot computer 2.0 or 2.5.

Tesla Sentry Mode is a valuable security feature that can help protect your vehicle from potential threats. By following the steps provided, you can set up, enable, and customize this feature to fit your needs. As a Tesla owner, using Sentry Mode can give you peace of mind, knowing that your car is actively monitoring its surroundings for potential threats. While no security system can prevent all attacks, Sentry Mode offers an added layer of protection that can help deter criminals and keep your vehicle safe.

Tesla Building Cortex 2.0 Supercomputer at Giga Texas to Power FSD

Not a Tesla App

FSD’s insatiable appetite for AI compute is taking shape once again at Giga Texas, where Tesla is building out Cortex 2.0 — its second large-scale GPU supercomputer cluster — on the facility’s north side.

This confirmation comes thanks to the detailed research and findings by Giga Texas drone pilot Joe Tegtmeyer, who shared his findings on X.

For months, there has been some speculation on what this new site would be - new storage, the Optimus production line, preparation for the Cybercab’s unboxed assembly process, and more. Now, thanks to permits filed by Tesla, we know that this new area is destined to become the second supercomputer destined for FSD training. 

Cortex 2.0

There are some key details we can unpack from what we’ve learned about Cortex 2.0. The new facility will be on the north side of Giga Texas, opposite Cortex 1.0, which is on the south side. The permits explicitly tie the usage of this expansion to Cortex 2.0, namely through the fact that it is a data center.

This is actually a change from Tesla’s original plans - the northern section was intended to be used as a central campus support facility, with three smaller facilities and water storage tanks. Now, it has been redesignated as Cortex 2.0 and is one large structure.

The permits that have been filed have already been approved and cover the foundations, underground water mains, and building itself. The steel structure is actively being put together on the concrete foundations, and about 50% of the roof decking is already complete, bringing the exterior shell closer to completion.

Fueling FSD’s Brain

The deployment of Cortex 2.0 is the latest in Tesla’s massive and ongoing investment in the computational power required to train FSD. While this primarily covers FSD for cars, this will also eventually apply to Optimus, which is powered by the same AI4 computer and also runs a variant of FSD.

This isn’t Tesla’s first foray into large-scale AI infrastructure and won’t be their last. Alongside Dojo, their home-grown AI supercomputer, Tesla has been partnering closely with Nvidia to ensure they have the GPUs necessary to do all the hard work. Cortex 2.0 is the next iteration, and once it's fully online, we can expect that Tesla’s work on FSD will accelerate even further.

Especially since Elon is planning something truly outrageous once again:

Been thinking about the fastest way to bring a terawatt of compute online.

That is roughly equivalent to all electrical power produced in America today.

Tesla FSD in Europe: Highway Approval Expected to Arrive in September

Not a Tesla App

With European Tesla owners eagerly awaiting any news on FSD in Europe, we’ve seen Tesla tease FSD, and also point out exactly what the barrier has been - regulatory approval. Now, following the latest meeting of UNECE, new regulatory amendments are set to unlock “System-Initiated Maneuvers” (SIM) on highways across participating European nations.

This development, highlighted by Kees Roelandschap on X, notes that the latest documents from the United Nations Economic Commission for Europe (UNECE) center on amendments to UNECE regulation 171. These changes were formally adopted into UNECE during the WP29 World Forum in March 2025.

Now, the amendment that will enable SIM will come into force on September 26, 2025. This six-month period after approval is standard UNECE procedure and allows objections from party states that would halt the implementation. Objections to UNECE amendments are genuinely rare, with 95% of amendments passing without objection once the World Forum adopts them.

What This Means for FSD in Europe

System-initiated maneuvers will allow your Tesla to perform actions autonomously, such as changing lanes on a highway, while the driver remains fully responsible for supervision. This is a substantial step up from current regulatory standards that only allow for suggested maneuvers or require explicit driver initiation for every automated maneuver. 

This inches towards the more normal “hands-off, eyes-on” approach that Tesla has taken with FSD Supervised in North America and China. This regulatory change will help to provide the legal frameworks needed to deploy more advanced autonomy capabilities in Europe, at least matching what’s available on highways in North America.

Tesla is waiting for EU approval (sigh)

Highways Only

The UNECE regulation will apply to all countries that adopt its standards, including the European Union, Japan, and South Korea - unless they specifically block it. This is a relatively positive development, but there are some hiccups.

This regulation only allows for system-initiated maneuvers on highways, not low-speed roadways. That means the city streets portion of FSD’s capabilities - including handling ‘Start FSD from Park` and reaching your destination’s parking spot - still won’t be available in Europe. 

In addition, the UNECE framework has stricter requirements for driver monitoring and attentiveness - which means that some nags, including the dreaded wheel nag, are likely to remain a key portion of the experience.

Progress on autonomous driving regulations in Europe has been fraught with indecision and caution, which has been a source of frustration for many who are watching the everyday progress of FSD in North America, and more recently, in China. Even with individual countries recently approving testing of FSD on public roads, harmonized UNECE regulations are the key to wider, consistent deployment, which will allow everyday customers to use it as well.

While the path to full parity with North America may be long and involve even more regulatory machinations, the upcoming implementation of System-Initiated Maneuvers is a big step forward for Tesla owners in Europe. It is a key piece of the puzzle that will help Tesla bring some more features of FSD to Europe, assuming the September timeline holds.
