Built because a parked car shouldn’t keep its own evidence.

Sentinel started the usual way: a scraped bumper in a car park, a Tesla that had recorded the whole thing — and a USB stick that had already looped over the clip by the time anyone looked.

Sentry Mode watches faithfully. But everything it sees is trapped on one fragile drive inside the very object being damaged or stolen. The fix isn’t another cloud subscription that owns your footage — it’s getting every clip off the car, into storage you already own and trust, before it’s needed.

So that’s the whole product: a small device that pretends to be the USB drive, a quiet pipeline to your NAS or cloud, and a portal that proves — at a glance — that the watch is running.
