The night vision technology is used to see the surrounding region during night. And yes, the 2014 E class Mercedes came with a night vision technology, which is the advanced version of all the other night vision technologies with E class.
The drawbacks of the 2009 E-Class night vision were avoided completely in this device. The IR camera offers high resolution and it is operated with the rear camera and so the sources in the night are viewed clearly in the dark. This technology detects the sources and alerts the drivers with higher efficiency.
