GM’s OnStar Connected Cameras Put Tesla’s Sentry Mode On Notice, But Cloud Security Is The Catch
General Motors used its GM Forward tech showcase in New York on October 21, 2026, to unveil OnStar Connected Cameras, a surveillance feature that borrows the core idea behind Tesla’s Sentry Mode: using a vehicle’s existing exterior cameras to automatically capture footage when something happens to the car, whether that’s a crash or someone tripping the theft alarm. The system records roughly 30 seconds before and after a triggering event, works while the vehicle is parked, and saves clips to a new OnStar app rather than relying only on local storage.
That cloud-first approach is also where GM’s version splits from Tesla‘s. Sentry Mode saves footage locally to a USB drive and can start recording the moment someone gets too close to the car. GM’s system, according to OnStar executive director of product management Nick Festa, needs a more significant trigger, like an actual collision, an aggressive horn honk, or an alarm going off, and depends on a subscription and connectivity to get the footage into the owner’s hands.
What GM’s System Actually Captures And How It Differs From Sentry Mode
The Connected Cameras feature pulls footage from the same exterior cameras that already power Super Cruise and 360-degree parking views, so GM isn’t adding new hardware to enable this on compatible vehicles. When an incident occurs, the system saves a clip spanning about a minute total, 30 seconds on either side of the triggering moment, and uploads it to the OnStar app for the owner to review.
GM is pitching the feature specifically around post-accident confusion, the moments when two drivers walk away from a fender bender with two completely different stories about what happened. Festa confirmed to Inside EVs that the system also works while parked, so if a theft alarm trips, Connected Cameras generates its own 30-second recording of whoever triggered it. That’s a real-world use case Tesla owners already lean on Sentry Mode for, though GM’s bar for triggering a recording appears higher than simply detecting motion nearby.
The Catch: Subscription, Cloud Upload, And A 2027 App Launch
Unlike Sentry Mode’s local-only recording, GM’s Connected Cameras clips get uploaded to the cloud through the new OnStar app, which isn’t launching until 2027 and will replace the separate Chevrolet, Cadillac, Buick, and GMC apps. The feature will also require an OnStar subscription, though GM hasn’t said what that will cost. Access will initially be limited to select vehicles, including full-size SUVs and Cadillacs, delivered via an over-the-air update rather than arriving across the entire lineup at once.
That combination of subscription, cloud dependency, and a rollout window more than a year out means GM’s answer to Sentry Mode won’t be something current owners can simply switch on this week. Some GM vehicles already offer a taste of local recording. The Cadillac Escalade’s Surround Vision Recorder can save external camera footage straight to a USB drive, no subscription or app required. GM says Connected Cameras will offer that same kind of local recording in addition to the uploaded clips.
GM’s Privacy Pitch
GM is leaning hard on privacy messaging alongside the feature itself. The company says Connected Cameras recordings are end-to-end encrypted, and that only the OnStar account holder decides who, if anyone, gets to see a given clip. GM has also said it and OnStar cannot access the recordings themselves. That framing comes against the backdrop of a finalized FTC order earlier this year barring GM and OnStar from sharing certain consumer data with consumer reporting agencies, a history that makes the privacy emphasis around a new camera-based feature worth watching closely as more details emerge.
