GM OnStar Connected Cameras: Sentry Mode For Corvette
General Motors just gave performance car owners a reason to worry less about parking lots and shady street corners. At its GM Forward tech showcase in New York on October 21, 2026, the automaker unveiled OnStar Connected Cameras, a surveillance feature that borrows from Tesla’s Sentry Mode but triggers differently, which matters for Corvette owners.
Instead of waking up whenever someone walks too close, GM’s system only records when something serious happens, like the theft alarm going off. The exterior cameras that already handle Super Cruise and 360-degree parking views then capture 30 seconds of footage before the incident and 30 seconds after. For owners who’ve dealt with catalytic converter theft, key-fob relay attacks, or a mystery door ding, that beats hoping a stranger’s doorbell cam caught something.
A Higher Bar Than Sentry Mode, But A Smarter One For Theft
Tesla’s Sentry Mode starts rolling whenever it senses someone lingering near the car, which catches curious strangers but also records plenty of nothing. GM’s approach, according to OnStar executive director of product management Nick Festa, needs a more significant trigger, like a collision, an aggressive horn honk, or the alarm tripping while parked. The alarm trigger matters most for performance cars, since the 30-second buffer captures a thief approaching, not just fleeing after the fact.
Where Sentry Mode saves footage locally to a USB drive, GM’s Connected Cameras clips upload automatically to the new OnStar app. GM says the recordings are end-to-end encrypted, and only the OnStar account holder decides who sees a given clip, with GM and OnStar locked out. That matters for an automaker hit with a finalized FTC order earlier this year barring it from sharing certain OnStar driver data with consumer reporting agencies.
Escalades And Full-Size SUVs Get It Firs
Some GM vehicles already offer local recording, like the Cadillac Escalade’s Surround Vision Recorder, which saves external camera footage to a USB drive with no subscription required. Connected Cameras keeps that local option alongside the cloud upload.
Festa confirmed that “select” vehicles already on the road will get Connected Cameras first via an over-the-air update, starting with full-size SUVs and Cadillacs. The feature arrives through the new OnStar app, which launches in 2027 and replaces the separate Chevrolet, Cadillac, Buick, and GMC apps with one unified platform. It will also require an OnStar subscription, though GM hasn’t said what that costs.
For performance car owners stuck choosing between an aftermarket dashcam and hoping for the best, a factory system using cameras already installed is worth watching as the rollout gets closer. Enthusiasts have begged automakers for years to put all those backup and lane-watch cameras to better use, and GM finally listened, even if Corvette owners wait on the sidelines while Escalade buyers get first dibs.
