I got this camera to use with my Nextbase 322 GW Dash Cam. I chose this model because I wanted to have rear video coverage, but did not want to install a stand alone unit in the rear of my car. Installation was as simple as snapping it into the port of the dash cam. I had to reboot the camera for it to recognize, but once restarted I was immediately up and running. After installation the touch screen layout changed to include an option to toggle to the rear view and back. I have attached photos to show what it now looks like. When joined both the front and rear cameras are limited to 1080P 30FPS. I did not find this to be a problem because the video quality is sharp and clear. Vehicles, people and even license plates are easily captured. The rear facing camera captures video that is similar in perspective to what is seen when looking into the rear view mirror. It uses a telephoto lens with a 30 degree field of view that leaves some gaps in the side. After I connected both cameras I received a message that the SD Card I was using was not a U3 card and could not be used. It now requires a SD Card that is UHS Speed 3 and SD Speed 10. I am using it with a 128 GB SD Card and am getting 8 hours of front and 8 hours (16 hours total) of rear recording time. So remember that since there are two cameras and it only takes one SD Card, the normal recording time is half since the cameras are sharing the SD Card. This companion unit to the Nextbase Dash Cam suits my needs perfectly. Even though the rear recorded image is not as complete as a stand alone camera because of the side gaps, the convenience and simplicity is more than worth the trade off.

Great addition to a great dashcam. Added it to my 622gw, and works as expected. No fussing, just attached it and aimed it and it works. Very small footprint (see pics)

I recently purchased a Nextbase 322GW dash camera, and a large part of the reason I chose it was due to the availability of this rear-view camera module. No other dashcam (that I am aware of) offers this type of option and I wanted to be able to monitor traffic behind me as well as in front. The problem is that I drive a convertible, and most dashcams with a rear camera attach to the back window - obviously not an option when you have a convertible. There are some dashcams that offer a rear camera that can mount outside (like off the license plate bracket) but those require a lot more tricky wiring through the trunk, etc. This Nextbase solution is so much easier! Pros: Simple to install. Worked right away. Some users report having to restart the dashcam to recognize the camera, but that's not a big deal. Good picture. The lens is telephoto, so it does not capture the driver or passenger - it aims directly out the rear window. The lens itself is on a swivel - You can make fine adjustments to the angle of view without repositioning the camera. Cons: Makes the dashcam physically larger. It's not huge, but you will have to fiddle with the location to make sure the front camera has a good view, the rear camera has a good view, and the camera itself does not block your forward view or mirror. If you think you might add a camera module to your Nextbase, do not install the adhesive mount until you test it with the module! Otherwise you might end up having to unstick it and move it. Rear camera resolution is not identical to the front camera resolution - With my 322GW, I get 1080p from the front camera but only 720p from the rear. With the more expensive Nextbase dashcams, you can get 1080p from the rear camera but I assume it's limited by the write speed to the microSD card. Expensive - Although I really like this rear-view camera, it seems pretty pricey for what it is. I feel like a better price point would be no more than $50. In fact I've read that in Europe it sells for closer to that price. Nether Pro nor Con: Compatibility: The rear camera modules do not work with every single Nexbase dashcam. Basically the 322GW is the least-expensive model they work with. In short - I'm very pleased with this rear-view camera. It does exactly what I wanted it to do and works well. My biggest knock is the price, but I'm not aware of any similar product out there that gives you a rear view without the installation issues.

Great video quality but no option to zoom in or out. Note: you can’t record at 1440p if you add this on but you can still do 1080p 60fps front view and 1080p 30fps for the rear facing cam. Very simple, just plug and play.

Excellent camera. Takes up little space and gives decent view behind my vehicle. Easy to set up and use.
