The Vantrue N4 is the first 3-channel dash cam by a major manufacturer. Video quality is fair overall. It supports simple and time-lapse parking modes, and a GPS mount is available optionally.
First dual 1080p cam with a separate recording box you can stow away out of sight. Extremely small front and rear cameras: 28x28x32mm, or 1″ by 1″ by 1 1/4″. Good video quality at day, average quality at night. Optional GPS and CPL. Remote lock file button that can also be used to start and stop recording.
High quality video up to 1296p. Supports 2560x1080p wide screen. 16 Mbps bit rate and Ultra-High Dynamic Range (HDR) ensures great video quality at night as well as at day. Optional GPS tracker and CPL filter available separately. Uses capacitor instead of battery. Downside: Large size, not very discreet due to form factor.
An upgrade of the LK-7900 ACE, the Korean Lukas LK-7900 ARA has a couple of unique new features: an OBD-II interface, and up to 256GB memory support for over 48 hours of video recording. Also, the internal battery has been replaced by a capacitor. Of course it’s keeping the best features of its predecessor, like extreme temperature resistance and great video quality.
