Does anyone remember those SD cards that had wifi broadcasting capabilities for transferring content off of a dumb device? This was like 15 years ago. Seems they're not available anymore.
ETA: after some research, the brand was eye-fi and they bricked all the cards in 2016 upon going under. There are similar things out there now but availability and price aren't that great.
If they're so smart then why do they have issues that my dumb dash cam doesn't?
79% of smart dash cams we tested had security issues Out of 28, only six didn't have any concerns. Find out what problems we uncovered and how to keep your dash cam secure Callum Pears Researcher & writer
Callum pushes tech to its limits and has spent nearly three years bombarding antivirus with malware, taxing routers and inspecting computer monitors
Which? dash cam tests found security flaws and concerns in the majority of smart models we tested, and in some cases they were breaking the law.
Smart dash cams have wireless connectivity and features that use the internet. This could be tracking technologies, motion detection, voice assistant controls and voice alerts, as well as more advanced features such as automatic cloud backup, real-time alerts and remote viewing.
You're also able to transfer footage wirelessly to the companion app on your smartphone, which is much quicker and more straightforward than traditional dash cams, where you'd need to remove the SD or micro-SD card and copy the files over to your computer.
Although these features make a dash cam a more useful tool for drivers, they also expose you to potential security risks.
Our testing found numerous dash cams with multiple security vulnerabilities. In fact, of the 28 smart dash cams we tested, only six lacked security concerns.
Find out what problems we encountered, which manufacturers took action to fix the problems we uncovered, and what you can do to keep your dash cam secure.

Of all the issues we found, weak default wi-fi passwords were the most concerning security vulnerability because they mean that nearby hackers could connect to the devices and access data such as journey information, saved recordings and other personal information.
Since 2024, manufacturers have been obliged to ensure that default passwords aren’t easily guessable. This can be resolved by enforcing a mandatory password change or by assigning unique default passwords.
We contacted each manufacturer to share our findings and gave them an opportunity to comment and resolve our concerns.
Road Angel successfully addressed the issue with its dash cams, which now require changing the default password.
Miofive initially responded and released a firmware patch that fixed some of our other concerns, but didn’t resolve the default password issue. Miofive didn’t respond to our follow-up messages, and we received no response from Kitvison and Orskey.
In addition to weak passwords, we also found mediocre encryption on some dash cams. There were several exploitable security weaknesses that made it possible to intercept data, access, and potentially modify stored video files.
To do this would be difficult for hackers. In most cases, they would need to be very close to the dash cam to exploit it – but it's not impossible. Many of these issues are also exacerbated by the poor default wi-fi passwords.
Nextbase resolved our concerns with firmware patches. Miofive and Road Angel fixed some issues but not others, and we're continuing to work with Road Angel to get remaining concerns resolved.
Garmin reviewed our findings but stated that it believes that numerous factors 'limit the exploitability of any purported vulnerabilities such that there is no practical risk to our customers’. Kitvision and Orskey did not respond.
In an age of growing cyberattacks and sophistication among hackers, dash cam manufacturers should be placing the greatest emphasis on their devices' security, even if they think it's difficult to exploit or a niche weakness.
Why is PSTI important?
Dash cam showing the road ahead
The Product Security and Telecommunications Infrastructure (PSTI) Act came into effect in April 2024. It mandates that manufacturers, importers and distributors (such as retailers) have a duty to protect devices that can connect to the internet or other networks.
It states ‘UK consumers should be able to trust that these products are designed and built with security in mind’.
The PSTI Act specifies the publication of information on how to report security issues, details on how long manufacturers will ensure security patches are released and the banning of universal default and easily guessable passwords.
These factors are important for strengthening security defences and ensuring that manufacturers release updates to keep products safe from new threats.
Although the Act gives manufacturers time to bring their products in line with its standards, they’re now duty bound to investigate compliance failures and take action if required.
If manufacturers fail to act, then the Office for Product Safety and Standards (OPSS) will intervene. The OPSS is an enforcement authority responsible for ensuring compliance.
Strong legal protections and vigilant enforcement mean UK consumers can use smart devices – including dash cams – with confidence, knowing that non-compliance by manufacturers will have consequences.
Which? takes this seriously too, and we’ve already informed the OPSS about our findings, the responses we received from manufacturers and the concerns we still have.
3 steps to keep your dash cam safe and secure A person installing a dash cam in a car
There are some simple steps you can take to boost your dash cam’s security, regardless of what manufacturers do or don't do.
The most important thing we would encourage every smart dash cam owner to do right now is to update the wi-fi password.
This is used to connect to paired smartphones and transfer footage wirelessly to them. A weak or easily guessable password could, under the right circumstances, allow others access to your dash cam and its library of footage.
As our testing has found many manufacturers still fail to either enforce a mandatory change, or provide a unique default password – it's highly recommended that users update them independently to a strong, but memorable, alternative. Check out our guide to creating secure passwords for help with this. 2. Install firmware updates
In addition to resolving software bugs and performance issues, firmware updates also provide important security updates.
It's important to update both the dash cam itself and any companion app. These updates ensure both are equipped to deal with newly discovered or recently resolved security vulnerabilities. 3. Keep footage backed up elsewhere
It's good practice to ensure that captured video footage – particularly important footage (such as that showing an incident, accident, or crash) – is backed up securely and separately from internal storage and any subscription-based cloud storage you may be using.
The risk to footage located exclusively on the internal SD or micro-SD card is that it could become corrupted, damaged, lost or stolen.
Cloud-based storage is typically part of a subscription service (either from the dash cam manufacturer or a third party). The risk here is ending the subscription and losing access to the stored footage, which the provider may later delete after you've unsubscribed.
Back up footage on your computer or smartphone to keep it safe. Alternatively, for additional peace of mind, consider investing in a USB storage device or external hard drive to store your backed-up dash cam footage. Make sure to pick a model with a healthy amount of storage, as video files tend to be large.

Available from Halfords (£99), Nextbase (£99)
The Piqo 1K is one of the more affordable dash cams we’ve tested, but it doesn't come with a supplied SD card, which can easily catch you out.
It has a solid array of additional smart features, including GPS tracking, motion detection and the ability to access footage via the companion Nextbase app.
Footage is listed with thumbnails in the app, making it a doddle to cycle through them.
Check out the Nextbase Piqo 1K review to see if it's the right dash cam for you.
Am I going insane or is there nowhere in the article where they mention which 6 dash cams have no security concerns?
It's Which, they expect you to pay a subscription to find out
There is a good case to be made for "keep it simple". It sounds like a great idea to connect a dashcam to your phone, but that brings so much more complexity into it. Networking, security, updates, changing phone OS and so much more.
I started to buy simple "single purpose" devices without connectivity in the last few years and so far it has gone great. Yes, I might have to take out the SD card and put it in my computer if I want a dashcam video, but I know that my dashcam doesn't need updates, will work until some hardware failure sometimes in the future, I do not need to worry about some chinese cloud service going down or someone spying on me with the app.
I keep a usbc microsd card reader in my car. Allows me to copy footage right there so I do not have to bring the card to my computer. It's easy enough to transfer it from there.
Exactly.
In around eight years of using a dashcam I've needed the footage maybe three times.
Putting an SD card in my computer three times in eight years isn't anything I could call a major inconvenience.
I bought my dad the same camera. High quality recording, dead-simple, no frills and no hassle.
Joke’s on them. Mine is a Chinese company. I already know it spies on me. So does my car with its “disabled” cell connection that promises not to broadcast my whereabouts.
that's fine, if you only use it on private roads. but if not, you are recording plenty of people (even not counting drivers) who did not consent to being recorded.
then who knows what happens with the recordings. and that's the actual problem.
too bad its not enforced.
I've been shopping for a dash cam. It seems like all the brands are Chinese companies except Garmin?
I wouldn’t worry about it too much. You can get some without WiFi. You just have to yank the microsd if you want to see the files. The one I have has WiFi but it’s so slow I can’t even preview videos. I have to connect to its WiFi, so unless it’s randomly connecting to open WiFi’s while I’m driving without my knowledge, I can’t see how it would transit much.
Don’t spend too much though. They break after a couple years. Especially if you live in a hot climate like a desert.
Yeah. If you get one that only records to an SD card and has no wireless connections of any kind, it would be pretty hard for that to have any security/privacy concerns.
So does my car with its “disabled” cell connection that promises not to broadcast my whereabouts.
Find the antenna and physically unplug it.
Physically unplugging it may not be enough and risks permanent damage. Installing a 50ohm terminator is a much safer option on all accounts and takes just about the same amount of effort as unplugging it ( ~$10 extra).

Security issues? In a camera recording to an SD card without any connectivity?
Smart dash cams have wireless connectivity and features that use the internet. This could be tracking technologies, motion detection, voice assistant controls and voice alerts, as well as more advanced features such as automatic cloud backup, real-time alerts and remote viewing.
Oh, there's your problem...
I would love a DIY open source option but I haven’t been able to find cheap available sensors that would survive a hot car.
Then again if the security really is this bad, maybe you could jailbreak and toss your own firmware on existing cameras. Hmmm
Pro tip: many that ship with an SD inside will have the factory firmware and device-specific keys still recoverable on the card (secure erase is too slow for production I guess) so before turning the device on for the first time, remove the card and image it for maximum chance of recovering the FW intact.
Use one without connectivity. Or get a microSD to SD adapter and a Wi-Fi-enabled FTP SD card... but I don't think they make these anymore, much less durable, fast, high-capacity ones. Or get a USB-C microSD reader and keep it in the car if your phone has no free microSD slot.
Those WiFi SD cards probably aren't any more secure than the cameras.
If the camera supports downloading video over USB, you can get a USB OTG cable to connect it to a phone or tablet. Otherwise a card reader is the way to go.
I have one that crashes and resets itself a lot. My settings are mainly suggestions. It’s like a windows machine in my car and I hate it. Fucking Thinkware trash.
