Protection is probably worth the loss though.

Sentry Mode protects your Tesla from break-ins and thieves, but how much does it drain the battery when activated? More specifically, what level of draw does Sentry Mode have on the Model 3 battery?

We know that Sentry Mode requires juice to operate when activated. That's obvious. But is the draw on the battery substantial or is it low enough that you can activate Sentry Mode at will?

You can find out what the expected level of draw on the Model 3 battery is in this video right here from our friend Tesla Raj.

We suspect that over time, Tesla will find way to reduce the draw of Sentry Mode, but even right now it's not that big of an issue. Activate it as deemed necessary and don't fret too much.

Sentry Mode: Guarding Your Tesla

The Tesla Team – February 13, 2019

According to federal statistics, there was an estimated one motor vehicle theft or attempted theft every 40.8 seconds in the United States in 2017— and that doesn’t even include the vast number of car break-ins that happen nationwide. To further enhance the security of our vehicles and give our customers additional peace of mind, today we’re starting to roll out a new safeguard – Sentry Mode – to protect against break-ins and theft.

Sentry Mode adds a unique layer of protection to Tesla vehicles by continuously monitoring the environment around a car when it’s left unattended. When enabled, Sentry Mode enters a “Standby” state, like many home alarm systems, which uses the car’s external cameras to detect potential threats. If a minimal threat is detected, such as someone leaning on a car, Sentry Mode switches to an “Alert” state and displays a message on the touchscreen warning that its cameras are recording. If a more severe threat is detected, such as someone breaking a window, Sentry Mode switches to an “Alarm” state, which activates the car alarm, increases the brightness of the center display, and plays music at maximum volume from the car’s audio system.

If a car switches to “Alarm” state, owners will also receive an alert from their Tesla mobile app notifying them that an incident has occurred. They’ll be able to download a video recording of an incident (which begins 10 minutes prior to the time a threat was detected) by inserting a formatted USB drive into their car before they enable Sentry Mode.

Sentry Mode must be enabled each time a driver wants to use the feature by going to Controls > Safety & Security > Sentry Mode. The feature will begin rolling out today to U.S. Model 3 vehicles, followed by Model S and Model X vehicles that were built after August 2017.

While no alarm system can prevent against all vehicle thefts, break-ins and threats, we hope that with Sentry Mode and our other security features, your Tesla will be even more secure.
