Hm, let's see: Do I want to wear out the flash memory in an $800 phone, or get a $150 dash cam?

This comment applies to Android phones that wouldn't let this thing write to a micro-SD card, of course.

Yeah, all I could think of was "that's an insane amount of thrashing on the storage on this very expensive phone" alongside my second thought which was: "My Pixel 7 Pro can't record video for more than a couple minutes before it microwaves itself into oblivion, there's absolutely no chance it survives for even a couple seconds as a dashcam."

I mean, if you've got to put in a dock/holder anyway, why not use external storage?

It'll probably be an in-memory circular buffer of the last n minutes, and then you get to save it if anything happens

+1 and copy buffer to storage immediately if the gyro detects a abnormally sharp movement

One problem is that virtually all dash cams use the same sensor that kind of sucks. You're usually not able to make out people's license plates.

I installed a new one with the new sony starvis 2 sensor, it can read license plates at night pretty good I would say.

My dashcam was priced like a new iPhone but the recording quality is superb, licence plates of a car 10m away is clearly readable.

Do tell!

I believe it's called Aviline DVR-B

you can buy comma.ai hardware, its base use is "dashcam"

you can, at your discretion, load self-driving software (openpilot), which can take over driving for you, in addition to maintaining dashcam footage

they have a subscription that will store footage in the cloud too, iirc

And their flash is known to brick a lot

I had a pixel 3xl bricking after an update. They get a lot of updates and wear the ?cheap flash

Bad flash in phones isn't that uncommon or specific to Google. There's at least a few Samsung phones whose flash dies after two years due to a firmware bug in the emmc. Samsung of course never fixed it since they just ran the clock on the warranty. There was at least once individual once refurbishing said failed phones by using a exploit to update said emmc.

And the $200 dashcam usually have super capacitor instead of battery for reliability

Time to put that 5G hype to the test, stream it directly to google servers like Nest cam cvr

You've worn out the memory in your phone before? How do you pull that off?

I've never worn out NAND flash on my phone, but I'm not sure if I record 3h of video everyday. 16Mbps * 3h = 20GiB, so 6 TBW for 300 days)
