Less than a month after Elon Musk said Sentry Mode for Teslas would "come soon," the update began to unfold along with a few other tweaks. In a detailed Sentry Mode blog, Tesla explained that he used the car's external cameras to monitor potential threats. If it's in standby, the cameras look ready to get into Alert status if someone does something like leaning on the car that pops up a message on the touch screen that the cameras are recording.
If someone breaks a window or something else, then it goes directly to Alert, which activates the alarm, plays music to loud sound and increases the brightness of the interior screen. He also sends a warning to the owner via his Tesla app and if they have a formatted USB drive before activating Sentry mode, then he will record a recording of everything that begins ten minutes before triggering the alert. You'll need to turn on Sentry mode every time you want to use it ̵
Sentry mode continuously tracks the car's surroundings while locked and parked. When a potential threat is detected, the car chambers will start recording and the alarm system will be activated. You will receive an alert from the Tesla application to let you know that an incident has occurred.
To enable Sentry Mode, go to Controls> Safety & Security> Sentry Mode. You must reactivate this feature every time you use it.
Sentry Mode is designed to add yet another layer of protection to your car, but it will not prevent all possible threats.
