Sentry Mode, Tesla's camera-based car alarm and surveillance system, allows the vehicle to detect potential threats near the vehicle.
When Sentry Mode is enabled it records from four different cameras when the vehicle detects someone near the vehicle or an intrusion.
Although the feature is fantastic and has caught many situations when damage has been done to the vehicle, it can also lead to dozens of recordings when there is no threat at all. This is especially true if its raining, which can trigger Sentry Mode events, or if the vehicle is parked on a busy street with a lot of foot traffic.
With update 2022.44.2 Tesla is introducing two new features to Sentry Mode in some markets. Depending on your region, you'll either get the ability to disable camera-based detection or the ability to disable camera-based detection and the ability to adjust the length of each clip.
Camera-Based Detection
The first is the ability to turn off camera-based detection so that Sentry Mode will only save recordings that are triggered by intrusion, such as a glass breaking, a door opening, or the vehicle's tilt sensor being triggered (only available in some markets).
Turning off Sentry Mode recording when the cameras detect someone near the vehicle will greatly reduce the number of recordings, however, it could also lead to some threats going undetected.
Sentry Mode Clip Length
Tesla is adding improvements to Sentry Mode
Not a Tesla App
The second new feature of Sentry Mode is the ability to adjust the length of a recorded event. Once a potential threat is detected, Sentry Mode will record for the next several minutes unless additional threats are detected. The number of minutes that Sentry Mode records after a threat has been static up until now. With 2022.44.2, you'll now be able to adjust the length of each Sentry Mode clip.
This feature is currently limited to many parts of Europe. Tesla's release notes for those receiving both Sentry Mode improvements read as follows:
Sentry Mode now allows for even greater customization, including:
- Camera-Based Detection, which allows users to disable use of cameras to detect threats.
- Sentry Mode Clip Length, which allows users to specify the length of the clip when a potential threat is detected.To adjust these Sentry Mode settings, tap Controls > Safety > Sentry Mode.
Other Improvement Coming?
Two other Sentry Mode features have been rumored in the past when Elon Musk responded to users on Twitter.
While there is no guarantee that these features will be implemented, in general, it does show that Elon Musk thinks they're a good idea and he'll likely share them with the team. The outcome of whether these features get added largely depends on the feasibility of implementing such features, Tesla's roadmap, and the effort required to develop them.
Also in 2020, Elon replied to a user on Twitter suggesting that Tesla would allow an 'incognito' Sentry Mode. The goal is to not let perpetrators know that they're being recorded, although there could be potential legal ramifications to adding such a feature.
In update 2022.24 Tesla added the ability to disable Sentry Mode sounds when an intrusion is detected. This could have been Tesla's compromise when trying to create an incognito mode. Although the car will no longer make any audible noise, it will still flash its lights and display the Sentry Mode logo on the screen letting individuals know that they're being recorded.
Tesla recently added Sentry Mode support in Israel and expanded the countries where Sentry Mode Live Access is available. The feature is now available to users in Hong Kong, Taiwan, Australia, New Zealand, South Korea and Singapore.
Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
