The Nextbase rear view camera is equipped with a narrower telephoto lens to capture the view of the road directly behind your vehicle. The recorded view is similar to the image in your rearview mirror. It uses a 30° telephoto lens to look back through the vehicle and capture the details of the road behind you to ensure you are protected from tailgates and rear-end collisions. The rear view camera can be easily installed by clicking it into the front of your Nextbase Dash Cam model. Compatible with Nextbase 322GW, 422GW and 522GW models If you are using a rear camera module, the resolution of your front camera is automatically adjusted to manage the two high resolution video files. The options for these settings are 422 / 522GW Front 1080p Rear 1080p OR Front 1440p Rear 720p 322GW Front 1080p Rear 720p
