The Nextbase Rear-View Camera is designed with a narrower, telephoto lens, to record the view of the road directly behind your vehicle. The view recorded is similar to the image seen in your rear-view mirror. It uses a 30° telephoto lens to look back through the vehicle, capturing details of the road behind, making sure you are guarded against tailgaters and rear end impacts. The Rear-View Camera can easily be installed by clicking it into the side of your front facing Nextbase Dash Cam model. Compatible with Nextbase 322GW and 422GW models. When you are using a rear-view camera module the resolution of your front camera will automatically adjust to manage the two high-resolution video files. The options for these settings are 422GW Front 1080p Rear 1080p OR Front 1440p Rear 720p 322GW Front 1080p Rear 720p.
