Tesla's Sentry Mode security system is a car thief's worst nightmare. When activated, 360-degree exterior cameras monitor the surroundings of an owner's Model 3, S, X, or Y and records incriminating video footage if any suspicious activity is detected. Not only can it help protect owners from vandalism, thefts, or break-ins, it can also record car crimes that happen nearby. In Australia, a group of thieves attempted to steal a Model 3, but the owner, Australian radio host Annabelle Brett, smartly used her Tesla mobile app to troll the thieves.

Early in the morning, the radio host received a notification on her phone alerting them that her Model 3's alarm was triggered. She then discovered her Model 3 had been stolen from her parking garage.

Fortunately, Brett had activated Sentry mode and was able to access footage catching the thieves in the act from the car's cameras on her phone. Unbeknown to the clueless car thieves, Brett was tracking their every move on the Tesla mobile app and eventually caught up with her Model 3 using a friend's car. "On my car phone app, you can actually see where the car is. We noticed that it was just around the corner so without thinking, I jumped in the car called the police… and just basically followed them on the map," Brett told 9 Now.

But rather than just tracking the Model 3 and following the thieves, Brett decided to use the car's advanced remote technology and give the thieves an experience they'll never forget.

"My phone app has the ability to slow down the car and also mess with it a bit, so I was able to put the windows down, beep the horn and basically screw with them as they were driving it," she explained. These scare tactics worked, and Brett was able to successfully foil the theft. After being warned that the authorities were on their way, the thieves swiftly abandoned the Model 3.

They were in such a hurry, that one of the thieves left a driver's license inside the Model 3 that helped identify them. Footage recorded from Sentry mode also helped identify their accomplice. If she had Tesla's Full Self-Driving software, Brett could have even summoned her Model 3 if she was close enough, which would have spooked the thieves even more.
