Over the past couple of years, there have been a series of unfortunate incidents involving people deliberately damaging parked Teslas. These are acts of vandalism, plain and simple. Tesla CEO Elon Musk was soon made aware of these troubling occurrences and Sentry Mode was soon born.

This system, designed to protect against vehicle break-ins and theft, utilizes Tesla's external cameras to continuously monitor the environment around the car when it's left unattended. If it detects a threat, like someone leaning up against the car, the cameras will automatically begin recording. That vandal will be caught red-handed. And now we're hearing Sentry Mode will soon receive a very useful upgrade: intruder alert.
