Videos recorded by a dash cam in a low light environment such as dark alleyway or underground parking lot can pose difficulties when you try to accurately identify information from the image. Important clips and images may get deleted due to insufficient memory space during long continuous recordings, especially in standard parking recording mode which requires large memory for saving 15 to 30 frames per second. CMOS Image Sensors allow constant front and rearview Full 1080p HD resolution recording during both daytime and nighttime along with a 140-degree wide angle lens view. This will minimize blind spots to assure recording of all events without fail.
