Tesla software update 2021.40 to add 'Live Camera Streaming'

By Nuno Cristovao

Tesla is on a roll with it's app lately. We've seen numerous releases since the app was updated to version 4.0 back in August. Just yesterday Tesla released version 4.2.0 with quick action buttons in one of its widgets and much better interior details of the vehicle.

With this same release, it looks like Tesla is starting to prepare to release a much anticipated feature in the near future, the ability to stream live video from your car.

Live Stream Video From Car

With the release of software update 2021.40, Tesla will allow you to stream live camera feeds from your car directly to your phone. You'll be able to view any of the cameras that are included in Dashcam or Sentry Mode, which include the front and rear cameras and the two side fender cameras.

When viewing the live feed from your car, you'll also be given the chance to save the video directly to the car. It's possible that Tesla will allow you to save it to your phone, but judging by the fact that Tesla is requiring your car to have a USB drive in order to stream video and that there is a new API endpoint to save dashcam footage, it's likely that the recorded video will be saved to your car instead of your phone.

View Sentry Clips and Dashcam Footage

In addition to being able to view live video from your car, and notably more useful. You'll now be able to remotely view Sentry Mode clips instead of having to wait until you get back to your car.

You'll likely be presented from a similar interface that appears in your car to view Sentry Mode and Dashcam clips and you'll be able to view and delete them.

Requirements

There will be a few requirements before you're allowed to stream video to your phone. Your car will obviously need to have the ability to use the Dashcam and Sentry Mode features, which require a vehicle with FSD HW 2.5 or higher. It will also require your vehicle to have software update 2021.40 or higher.

In addition, before being able to initialize the video stream, Tesla will require that your car be in park, have all doors closed and for no one to be in the car. Tesla is making these requirements presumably for privacy concerns around spying on individuals in a private environment.

Premium Connectivity Required

It's strongly suspected that your vehicle will need to be subscribed to Tesla's Premium Connectivity or be connected to WiFi in order to stream live video or remotely view Dashcam or Sentry Mode videos.

Tesla will very likely not introduce a higher priced connectivity option. Tesla already allows you to stream video services for unlimited periods. The bandwidth required to stream your car's cameras will be fairly small when compared to streaming video.

Limitations / Daily Limit

Tesla will impose a daily viewing limit on how long you can remotely monitor your vehicle with video. This is likely to prevent users from live streaming video for long periods of time. For example, if they went out to dinner, started a live stream and set their phone down.

I suspect the daily limit will be more than reasonable and you'll be unlikely to reach the limit unless you're trying to use your car as a security camera.

Talk to Car From Your Phone

When monitoring your car remotely, you'll be able to talk directly to your phone and have your voice come out of the car. This will require your vehicle to be equipped with the Pedestrian Warning System (PWS). Basically, if you have the Boombox feature, then you have the PWS.

In addition to being able to talk to the car from your phone, you'll also be able to honk the horn and flash your car's lights to alert anyone around your vehicle.

This snippet was found in the latest Tesla app:

"Tesla allows you to use your microphone to speak through your car or attach videos when scheduling service for your vehicle",

If you don't, then for some models Tesla can retrofit the PWS for a couple hundred dollars, although it's not available on all model years. Your car will need to already be wired to support the outdoor speaker.

I can see this feature being fun, but also useful. If there's someone seriously looking at your vehicle with ill intent, then what better way to deter them then to talk to them. They'll likely think that you're walking up to the car and walk away.

Of course, I'm sure there will be lots of humorous ways owners will use this feature as well.

Unfortunately, because Teslas do not (yet) have external microphones, this will be one-way audio. So you'll be able to talk to the individuals, but unfortunately unable to hear their surprised or funny reactions.

In-Car Purchases

As we talked about back in August, Tesla is adding in-car purchases. Features that you can buy directly on your phone today will become available in the vehicle as well. Features such as adding the FSD subscription, Performance Boost and others will now be only a couple taps away.

According to information in the latest iOS app, this feature will also be added in the 2021.40 software update.

As the owner of the vehilce, you'll see be able to limit in-car purchases as well, much like you can limit in-app purchases on other platforms.

Software updates have contained slightly less than usual lately as Tesla focuses on FSD and catching up on the new Model S software, but 2021.40 is surely to be an exciting release, even if this was the only feature in it.

Stay tuned for more.

Tesla Activates In-Cabin Radar in Software Update 2025.2.6

By Not a Tesla App Staff
Not a Tesla App

Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.

Why Not Vision?

Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.

What Tesla Announced

Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.

Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.

New Feature in Update 2025.2.6

Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.

In the release notes, Tesla describes the update as:

“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”

For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.

Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.

Supported Models

Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.

The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.

At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.

We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.

Tesla Updates App: Adds Robotaxi Code, New Model Y Models and New Tesla Service UI

By Karan Singh

Tesla has updated the Tesla app to version 4.42.0, and this time, it’s more than just bug fixes. The app includes a new service interface, introduces support for the new Model Y, and, for the first time, includes some code for the Robotaxi coming later this year.

This update was released for iOS and should be available on Android within a few days.

Refreshed Model Y 3D Model

First up in the update is the introduction of the 3D model for the refreshed Model Y. Interestingly, while we all know it as Juniper, the file code name inside the update lists the vehicle as “Bayberry.” The Bayberry name was introduced in Tesla app update 4.41.5.  Tesla’s internal code names sometimes change as the vehicle evolves - and we’ll continue to refer to it as the refreshed or new Model Y for ease of understanding.

As usual with Tesla’s 3D models in the app, there’s a lot of detail, although it’s not easy to see since you can pinch and zoom the model in the app. The 3D models used in the app are actually the same models that Tesla uses in the vehicle, although sometimes they include different lighting effects, but they’re all highly detailed.

Robotaxi API

Tesla has added a new endpoint in their app for Robotaxi - and it’s the very first Robotaxi or Cybercab-related item we’ve seen in the app. With the Robotaxi fleet launching in June, according to Tesla, it looks like they’re now adding support to the Tesla app.

The new app API is called “rides_feedback_upload,” which seems pretty explanatory. Tesla will need to gather a lot of information on ride quality and all the little things in between. What better way than to get feedback directly from users?

While Tesla previously released prototype images of what the Robotaxi app will look like, the introduction of this API into the Tesla app leads us to believe that Tesla will utilize the current app for Robotaxi use.

Updated Service Interface

Tesla has released an updated UI for the Tesla Service panel, and we have a ton of details on these changes. This new pane displays appointment details more prominently. If you have a service appointment scheduled, you’ll now see a lot more details on the main service screen. The app will now display:

  • Your current service status

  • Appointment date and time, which you can now tap on to add the event to your calendar

  • Address and hours of the service center. You can now also tap on the address to open up the location in your maps app

There’s also a new appointment details screen (the right portion of the image). This screen displays additional details that were previously unavailable, such as your transport type. The app will display whether you’ll get a loaner vehicle, demo vehicle, or something else.

There are a ton of user experience (UX) improvements in this update regarding service, including clearer language, improved UI fixes to images, and more.

Tesla has been making a lot of positive updates to the Service-related sections of the app lately, and we’re happy to see these coming rapid-fire. Tesla Service is now easier to use and understand. In the previous app update, Tesla also added the ability to pull down to update the service screens.
