原文說法有語病，改寫後依然存在。

"A crash or "unusual motion” of the vehicle can automatically trigger the camera’s recording function, the recorder may not store more than 30 seconds of data before and after the event that triggers its recording function.

30 seconds of data before and after the event
如果是事件觸發後開始錄像，怎麽可能錄到觸發前30秒的視頻？那時還沒開機呢。
