At most, this device seems trustworthy exactly to the extent that you trust that hardware hasn't been tampered with. Since there's very little information about how the tamper-proofing works, I tend towards skepticism. At worst, they've implemented a cryptosystem that, having never been peer reviewed, is vulnerable to basic attacks. Since I can't find out who the authors are, and they use both AES and Serpent with li…

Forgive me for being a bit blunt - but is that picture not just a painted mac mini? The edge has the inset line where the case turns from metal to plastic and the port area is the white plastic. Is this a Mac Mini + software + camera?

That's not a unique form-factor.

I was pretty interested in the site and product, until I saw the price

$6k is a lot for what on 1st impression 'looks' to be targeting the lower end of the security imaging market. You can buy three HD Axis IP cameras for that money. Speaking of cameras, you don't show or give any specs which is really strange when you're asking for 6k

the more I read your site the more I can somewhat understand the price, but if I was just a customer - you would have lost me in 30 seconds; your landing page doesn't convey your product's 6k of value

Still, kudos for not coming up with yet another web app

Earlier quoted context omitted.

Ditto. I'm a grad student studying security, and I'm not convinced that this is deniable. How will you deny the DV box (or even unlabeled camera & microphone) in your meeting area when the feds suddenly raid the place? How will you deny the private key on that USB drive you are very very careful to store securely, lest you lose the ability to view the video? I believe that history predicts that once the existing of t…

Regarding the "private key on the USB drive", I think the USB drive contains their software. Your private key is typed in at a password prompt. Regarding the "contempt of court" threat, they need to implement hidden volumes, like TrueCrypt does, and that will be addressed.

The password prompt is for a passphrase to unlock the private key. It's standard to encrypt the private key using the passphrase to provide some protection against the loss of the key.
