What is Tesla Sentry Mode and how does it work?

Tesla offers a feature, called Sentry Mode, which is an anti-theft measure installed in all its vehicles. Sentry Mode uses the cameras on the car and constantly monitors activities around a Tesla vehicle once a proximity alert is triggered. It’s meant to provide protection, or at the very least serve as a deterrent to thieves who try to steal Teslas thanks to flashing lights and loud sounds.
