The System on Module board is an Inforce 6601 SOM. [0]
It uses a Qualcomm Snapdragon 820 and they provide prebuilt Ubuntu Linaro distros for it, preconfigured for the board.
The camera manufacturer likely just tossed it straight in as configured and thus didn't know how the full disk encryption was setup.
This whole camera design looks like one of those 'we gave this project to some undergrad engineering students who've never designed a commercial product before and had no price target and thus it has a whole damn embedded linux system inside it for merely taking some HD video and stills triggered by some external wiring and saving them to an SD card'.

Wouldn’t it have been streaming it to disk without creating the file? Kinda like how if your camera dies while it’s recording, there is no recording. You have to manually recreate the file.
Figure 3 from the report- that's an Adafruit sensor module on a 3d printed bit of plastic with a teensy-brand microcontroller just sitting in there! Actually, the entire electronics enclosure appears printed.
Very funny to see in what I assume is a million-dollar product.
If a hardened camera can survive, I'm surprised subs don't have a floating black box that can survive an implosion and then float to the surface and begin emitting a radio signal.
I guess the trick would be finding a way to securely attach the black box in a way that would ensure its release in a catastrophic disaster.
> No deep-sea shenanigans around the Titanic wreck were revealed. Manley explains in his Twitter thread that “the camera had been configured to dump data onto an external storage device, so nothing was found from the accident dive.” Nothing particularly pertinent to the tragic accident, that is.
This is about camera hardware and how it survived. It provides no information or footage about the incident (in case you were looking for it like I was).
Them sandisks need to be pretty tough to not vaporize whilst cooking your USB ports. Ever notice how infernally hot they get under large file transfers?
I know the default policy is to use the source headline, but I feel the mention of $62 is kindof unfair. It evokes cheapness. Many many aspects of the craft were cheap and underbuilt, but it’s not clear to me that the memory card was one of those areas. Seems like it was an actually useful COTS part

Why are they crediting Scott Manley instead of just grabbing the images from the reports themselves? It sounds to me as if they wrote an article based on the video, and not based on the report. Very lazy journalism.

Some key points:
1. The Camera+Card was encased in a separate enclosure made of titanium+sapphire, and did not seem to be exposed to extreme pressures.
2. The encryption was done via a variant of LUKS/dm-crypt, with the key stored on the NVRAM of a chip (Edited; not in TrustZone).
3. The recovery was done by transplanting the original chip onto a new working board. No manufacturer backdoors or other hidden mechanisms were used.
4. Interestingly, the camera vendor didn't seem to realize there was any encryption at all.

I wonder what the price of the enclosure was then. Feels a bit like click bait...

Tech users get upset when you make me do what you want instead of what the user wants.
