Erin Andrews got her guard up at LAX when a taxi driver started recording video of her.
It all went down Friday afternoon after Erin landed in L.A. -- and you'll see in this clip ... she was fine talking to our camera guy and with a nearby still photographer.
But the "Dancing with the Stars" and FOX Sports host is clearly still on edge about video cameras she's not expecting -- after her whole hotel room peephole ordeal.
Watch, seems like Erin's cool with everyone playing their role -- but the taxi driver shooting freaked her out ... and it ended up costing him.
