Sentry Mode & Video Surveillance

Introduction

Video surveillance is becoming a core part of EV security. With multiple cameras already integrated into most modern EVs — for driving assistance, parking, and navigation — manufacturers are now extending their use to monitor threats and record incidents while the vehicle is parked.

This chapter explores how systems like Tesla’s Sentry Mode and others leverage onboard video, motion detection, and cloud integration to provide a digital witness for theft attempts, vandalism, or suspicious activity around the vehicle.

What Is Sentry Mode?

Sentry Mode is Tesla’s proprietary surveillance feature that activates when the vehicle is parked and locked. It uses the car’s external cameras to:

• Monitor surroundings for motion or proximity
• Record video clips when a potential threat is detected
• Flash lights or display warning messages to deter intruders
• Notify the owner via the Tesla app

Sentry Mode turns the EV into a passive surveillance device — acting both as a deterrent and an evidence collector.

How Video Surveillance Works in EVs

EVs equipped with surveillance functionality typically use:

• Multiple exterior cameras (front, rear, side)
• Parking sensors or motion triggers
• Onboard storage (e.g., USB drive, internal SSD)
• App integration for alerts and playback

When activated, the system continuously monitors for movement near the vehicle. If a specific threat threshold is met, it saves a short video clip — usually a few minutes before and after the event.

Common Features

| Feature | Description | |--------|-------------| | Live View | Some systems allow users to watch a live video feed from their app | | Event Recording | Clips are saved when motion or impact is detected | | Cloud Backup | Video is uploaded to cloud storage (requires subscription) | | Manual Recording | Users can save footage on demand via app or in-car button | | Privacy Zones | Some systems blur or ignore activity in private areas |

These features vary by brand, model, and subscription plan.

Example EV Models with Surveillance Modes

Benefits of Integrated Surveillance

• Visual Evidence: Helps identify suspects after a break-in or hit-and-run
• Theft Deterrence: Cameras and screen warnings can scare off intruders
• Real-Time Awareness: Owners can receive alerts within seconds of activity
• Insurance Support: Video can support claims or verify damages

For EVs left charging in public areas or parked overnight, these systems offer a strong layer of passive protection.

Considerations and Limitations

• Privacy Concerns: Always check local regulations — continuous recording may not be allowed in all countries
• Data Usage: Cloud-based systems may require subscriptions and consume mobile data
• Power Draw: Some features can drain the 12V battery if left active for long periods
• Storage Management: Users may need to manually manage storage devices (USB sticks, SD cards)

Summary

Sentry Mode and video surveillance features give EVs an added layer of smart security. By using built-in cameras to monitor surroundings, record incidents, and notify the owner in real time, these systems offer protection that goes beyond traditional alarms.

Combined with app-based controls and cloud connectivity, video surveillance transforms the vehicle into an active participant in its own security — and a valuable source of evidence when needed.
