GM's OnStar Cameras Take Aim at Tesla's Sentry Mode, But Pull Their Punches

General Motors is turning the fleet of cameras already bolted to its vehicles into an evidence-collection tool. At its GM Forward tech showcase in New York, the automaker revealed OnStar Connected Cameras, a system that grabs footage from a car’s existing exterior lenses and pushes the clips to the upcoming OnStar app.

The obvious comparison is Tesla’s Sentry Mode, and GM isn’t pretending otherwise. But the two systems don’t behave the same way. Sentry Mode tends to wake up when somebody lingers too near the car; GM’s version waits for something more serious to happen before it fires.

“It’s aimed at those messy minutes right after a collision,” GM’s Nick Festa, executive director of product management for OnStar, explained to InsideEVs, “when nobody can agree on what happened.”

How the recording actually works

When an event is triggered, the car saves roughly 30 seconds before and 30 seconds after, giving each clip about a minute of surrounding context. The cameras doing the work are the same ones feeding Super Cruise and the 360-degree parking views — no extra hardware required.

Parked cars get coverage too. If the theft alarm goes off, Connected Cameras can generate a 30-second event clip on its own.

Where it differs from what’s already out there

GM isn’t starting from zero. The Cadillac Escalade already offers a Surround Vision Recorder that writes the SUV’s external camera feeds to a USB drive. The new setup goes further — local recordings plus clips uploaded to the cloud and viewable in the app.

Privacy is the part GM keeps hammering on. Footage is end-to-end encrypted, and only the authorized OnStar account holder decides whether anyone else ever sees a clip.

• Select current vehicles: Full-size SUVs and Cadillac models are among those that will support the feature.
• Over-the-air delivery: The capability arrives via OTA update rather than a trip to the dealer.
• App consolidation: The new OnStar app lands in 2027 and absorbs the separate Chevrolet, Cadillac, Buick and GMC apps.

Why the timing matters

The announcement slots into a broader push by GM to squeeze more value out of the software and sensors already on its cars. It also puts the company on the same turf Tesla and Rivian have occupied for years — Rivian’s Gear Guard does much the same job on its trucks and SUVs.

For drivers, the appeal is simple: a fender bender turns into a file with timestamps instead of a shouting match with an insurance adjuster. Whether buyers see that as reassurance or surveillance will depend a lot on how clearly GM explains the encryption and sharing rules when the app goes live.
