Tesla dashcam backup

Your car records everything. Sentinel makes sure you still have it.

A small device that slots in where your Tesla’s USB drive goes and backs up every clip to storage you own — your NAS, your Dropbox, your S3 bucket — automatically, every time you park on home Wi-Fi.

The problem

Stock dashcam footage fails at the exact moment it matters.

01The USB drive fills, and the loop quietly overwrites the clip you needed.Overwritten

03Even when it survives, the footage never leaves the car — until it’s too late.Trapped

How it works

From the car to your storage — in three steps.

STEP 01

Capture & buffer

Sentinel replaces the dashcam USB drive. The car records to it continuously; buffered writes mean clips finish cleanly even through a power cut.

Acts as USBNo rewire
STEP 02

Offload on trusted Wi-Fi

Back home, the device joins your network and streams clips to your NAS on the LAN — or to your cloud via short-lived, presigned uploads over a TLS-pinned channel.

STEP 03

Review in the portal

Clips are indexed by day, hour and type. All camera angles play in sync; NAS clips stream at home from the device itself.

Your footage, your storage

The bytes never pass through us.

Your storageyou own it

The cloud brokers access and indexes metadata — it never proxies the video bytes.

Your storage of record

Footage is written straight into your own Dropbox app folder or your own NAS. We don’t keep a copy — there’s nothing on our end to hand over, leak, or lose.

Brokered, never proxied

To watch a clip, the portal mints a short-lived link and your browser streams the bytes directly from your provider. Uploads use presigned, put-only credentials.

Locked-down device

Every device-to-cloud connection is mutual-TLS and TLS-pinned. The device opens no inbound ports; remote diagnostics run only when you ask, over an outbound tunnel.
