Musk says Tesla has activated security cameras on vehicles at dealerships amid attacks

Tesla is stepping up security at its dealerships in the wake of vandalism and protests targeting Elon Musk's electric car company, the billionaire adviser to President Trump said on Thursday. 

"Tesla has ramped up security and activated Sentry Mode on all vehicles at stores," Musk tweeted.

When enabled, Sentry Mode keeps a vehicle's camera and sensors powered on and ready to record suspicious activity. "Think of Sentry Mode as an intelligent vehicle security system that alerts you when it detects possible threats nearby," according to the Tesla Model 3 owners manual.
