Tesla's HW3 and HW4 Cameras: Comparing the Differences in Quality and Hardware

Even after the camera improvements in Beta 11.4.7, HW4 cameras are still a leap ahead in clarity

DirtyTesla

Seeing is believing and more and more videos and images are popping up showing the difference between Tesla's Hardware 3 (HW3) and the latest Hardware 4 (HW4) cameras. The visuals highlight a radical transformation in video quality that paints an exciting future picture.

Improvements to HW3 Cameras

Tesla vehicles with the latest FSD Beta, version 11.4.7 include a notable visual improvement to the vehicle's camera feeds. With this update, Tesla introduced white-balance and color-balance corrections to the vehicle's camera feeds, making them look more realistic and accurate of the real world. But the biggest difference is actually the improvement in camera clarity. The visuals are noticeably sharper.

Our previous article and the included video demostrates the visual differences on HW3 cameras before and after applying FSD Beta 11.4.7. While these improvements are in a branch that is only available to FSD Beta testers (2023.7.30), it's likely that these video improvements will be applied to all vehicles in a future update.

Difference Between the Updated HW3 Camera Feeds to HW4 Camera Feeds

One of the best videos to date that compares HW4 to the new and improved HW3 cameras with Beta 11.4.7 was filmed by DirtyTesla, who did a nice job comparing the various cameras at the same location and in the same lighting. His findings and video are below:

Here is what stands out:

• A Leap in Resolution: The images demonstrated the stark difference between the 1.2-megapixel HW3 cameras and the newly introduced 5-megapixel HW4 cameras. This substantial upgrade in resolution has translated to a noticeable increase in clarity, allowing for the easy reading of license plates and road signs that were previously indecipherable with HW3.

• The Fish-eye Effect: Another captivating revelation from the images was the pronounced fish-eye effect in the rear camera of HW4. The images depicted a substantially wider field of view compared to the previous version, enhancing peripheral vision for a safer driving experience.
• Night-time Brilliance and Vibrant Colors: The comparison was confined to resolution and field of view and highlighted the improved night-time footage quality, exposure control, and more accurate color representation. This promises a more realistic and vibrant visual experience for Tesla owners.

What Does It Mean for Full Self-Driving?

While the images are impressive, the next set is how the camera technology will translate into improved Full Self-Driving capabilities. Elon Musk has hinted that HW4-equipped cars could be 3 to 5 times more adept at autonomous driving. We know that HW4 has more ports for additional cameras as well.

Retrofitting Possibility: A Disappointment

Now to remind you about the disappointing news for existing Tesla owners. These amazing images, courtesy of the new cameras might lead to inquiries about retrofitting possibilities. Unfortunately, the idea of retrofitting has been shut down for some time, in fact, Tesla has been trying to entice current Tesla owners into new Teslas by offering a limited-time transfer of FSD.

The comparison images between HW3 and HW4 cameras are more than just a technical showcase. It's visual evidence of how fast technology is changing and how Tesla continuously updates the hardware in their vehicles.

Tesla FSD in Europe: June Update

Not a Tesla App

The road to bringing FSD to Europe has been a long and complex one and filled with regulatory and bureaucratic hurdles. Elon Musk, as well as other members of Tesla’s AI team, have previously voiced their grievances with the regulatory approval process on X.

However, it appears that there is finally some progress in getting things moving with recent changes to upcoming autonomy regulations, but the process still seems slow.

Waiting on the Dutch

Elon commented on X recently, stating that Tesla is waiting for approval from Dutch authorities and then the EU to start rolling out FSD in Europe. Tesla is focusing on acquiring approvals from the Dutch transportation authority, which will provide them with the platform they need to gain broader acceptance in Europe. Outside of the Netherlands, Tesla is also conducting testing in Norway, which provides a couple of avenues for them to obtain national-level approval.

The frustration has been ongoing, with multiple committee meetings bringing up autonomy regulation but always pulling back at the last second before approving anything. The last meeting on Regulation 157, which governs Automated Lane Keeping Systems, concluded with authorities from the UK and Spain requesting additional time to analyze the data before reaching a conclusion.

Tesla, as well as Elon, have motioned several times for owners to reach out to their elected representatives to move the process forward, as it seems that Tesla’s own efforts are being stymied. 

This can seem odd, especially since Tesla has previously demoed FSD working exceptionally smoothly on European roads - and just did it again in Rome when they shared the video below on X.

DCAS Phase 3

While the approval process has been slow, Kees Roelandschap pointed out that there may be a different regulatory step that could allow FSD to gain a foothold in Europe.

According to Kees, the European Commission is now taking a new approach to approving ADAS systems under the new DCAS Phase 3 regulations. The Commission is now seeking data from systems currently operational in the United States that can perform System-Initiated Maneuvers and don’t require hands-on intervention for every request.

This is key because those are two of the core functionalities that make FSD so usable, and it also means that there may not be a need to wait years for proper regulations to be written from scratch. Now, the Commission will be looking at real-world data based on existing, deployed technology, which could speed up the process immensely.

What This Means

This new, data-driven regulatory approach could be the path for Tesla to reach its previous target of September for European FSD. While the cogs of bureaucracy are ever slow, sometimes all it takes is a little data to have them turn a bit faster in this case.

Alongside specific countries granting approval for limited field testing with employees, there is some light at the end of the tunnel for FSD in Europe, and hopes are that a release will occur by the end of 2025. With Europe now looking to North America for how FSD is performing, Tesla’s Robotaxi results could also play a role.

Tesla Launches 'TeslaVision' Contest With Big Prizes — See Last Year’s Winner [VIDEO]

Not a Tesla App

Tesla’s marketing has always been relatively unconventional, relying on word-of-mouth rather than traditional advertising. The passion of the owner’s community is always massive, but it is especially high now with the launch of the Robotaxi network just around the corner.

Tesla is now tapping into that spring of fan creativity and announced the TeslaVision video contest, with some seriously impressive prizes up for grabs.

Announcing the TeslaVision fan video showcase

Tesla owners & supporters have always been able to see our products & mission for what they truly are.

Your word of mouth has made Tesla what it is today.

The OGs will remember that in 2017, we held our first video contest. 8 years… pic.twitter.com/6pPpkqmqOH

The Contest

The core of the contest is simple. Create a video that shows how your Tesla gives you more in life. Tesla is looking for submissions that highlight themes of freedom, safety, fun, and convenience.

Prizes

The prizes definitely make this contest worth entering if you’re good with a camera and have some basic video editing abilities.

For North America, the prizes include a brand new Model Y AWD Long Range, alongside an all-expenses-paid trip to Austin for a tour of Giga Texas. The grand prize winner will also be able to custom order their Model Y, allowing them to select their preferred wheels and color.

The two runners-up won’t get a Model Y, but they’ll also enjoy an all-expenses-paid trip to Giga Texas for a tour of the factory.

The travel and tour include lodging in Austin for 2 nights, as well as economy-class round-trip tickets from anywhere in North America. Tesla will also provide a vehicle for use during the trip.

Hopefully, these winners will also have the opportunity to experience the Robotaxi network while they’re in Austin, as it’s expected to be opened to the public later this month.

Project Loveday

For long-time followers of Tesla, this contest may feel familiar. The contest is a direct throwback to the 2017 Project Loveday contest, which was inspired by a letter to Tesla from a 10-year-old aspiring marketer. That contest was won by MKBHD, with his submission below:
