Our Verdict
Integrated GPS and phone connectivity highlight Rove’s affordable R2-4K Dual, two-channel dash cam. I also like the rear camera being removable — a rarity. But captures are average at best.
The R2-4K Dual is basically the R2-4K Pro we reviewed not long ago, but with the addition of a rear camera. Most of what I liked then, I still like, and what I didn’t, I still don’t. A removable rear camera does prove an especially nice touch, however. And the price pushes this system into contention.
What are the Rove R2-4K Dual’s features?
The Rove R2-4K Dual is a two-channel, front/rear dash cam system. Front captures are 4K/2160p maximum (you can also use 1440p or 1080p to save space) while rear captures are 1080p. The front field of view is 150 degrees, while the rear is 140 degrees.
GPS is integrated into the camera and the resulting location data is watermarked onto the video. It’s also embedded into the files for playback purposes. And a shout out to Rove for actually employing it to set the time and date automatically. A sad number of vendors still don’t provide this amenity.

</div></figure></div>Above you can see the Rove R2-4K Dual’s 3-inch color display, the menu and function buttons, as well as the suction mount stuck to the rear window of my apartment. (Just in case you were thinking I’d driven into a garden.)
Suction mounts work far better these days than most people realize, but yes, once every few months you may have to re-affix it to the windshield. Rove thoughtfully provides a smaller, semi-permanent adhesive-type mount if you’d prefer a more lasting solution.
On the left of the camera are the TF card slot and power button, while on the right is the Type-C connector for the auxiliary power cable. The Type-C connector (kudos for modernity) for the rear camera is on the top right.
This brings us to a delightful touch for those who park a convertible on the street — a removable rear camera. Rotate the camera to the proper spot and it simply slides out of its mount.

Of course, you can set everything via the front camera using the display and buttons, but come on now. Most likely, this new model hasn’t been accommodated and by the time you read this you will be able to use your phone to adjust settings.

How much is the Rove R2-4K Dual?
The R2-4K Dual goes for $150, which is very competitive for a two-channel dash cam with integrated GPS.
How are the Rove R2-4K Dual’s captures?
Day captures from both the front and rear cameras were quite good, if slightly overexposed. You can adjust this in the settings, but I always capture with the defaults.
Rove also sent me a polarizing filter, which definitely solved the admittedly mild exposure issue, but also darkened captures at night. What I’m hoping for is that vendors start offering separate exposure adjustments for bright and low-light situations.
Details in daytime video are readily apparent with the R2-4K Dual; there’s not a lot of fish-eye for a 150 degree FOV, and color is largely accurate. But the stabilization wasn’t perfect — there was some jello wobble simply from the vibration of the engine.
