Off-the-shelf in the context of electronics means that they didn't custom design some parts of it (for example using a SoC module rather than custom DDR layout), not that the parts are consumer rated.
It is more than just parts though. To get past the more demanding EM compatibility/immunity certs you have to design the whole product with that in mind, at which point it stops being off-the shelf or inexpensive.
So you could basically deploy this as software only, on recent 820 based smartphones? Just need a fish eye lens attachment and CAN bus to USB cable (or USB OTG GPIO)
