A dash camera can record the scenes ahead of the car. But nowadays a single lens car DVR does not seem to meet drivers' demand. For extra security, many drivers now opt for a dual lens dash cam that records what’s going on behind the car as well as what’s happening in front. A dual lens dash cam actually consists of two cameras: A front unit mounted to your windscreen that records the road ahead of you, just like a single channel dash cam would. Additionally, a smaller camera records out of your car’s rear window simultaneously.
The Aoni 290 dual lens car camera
can record at 1080p resolution 1920×1080 pixels or 1280×720 wide screen alternatively). This camera’s video quality is very good at day time and fair at night. And this camera has wide angle distortion correction function to keep the footage clear. When an impact, emergency brake occurred or the car tilted, it will protect the previous, present and next video files automatically. With G-sensor the important files won't be removed by loop recording.
Both video and audio of the 290 dual lens HD car DVR
are good. The camera comes with a 3.0 inch screen and its interface is quite easy to use. It supports all the usual basics that any dash cam should have, such as auto on/off, seamless loop recording, and time/date stamp on video. More importantly, it has the Wide Dynamic Range (WDR) function to record the scenes even under poor lighting conditions.
