The ROVE R2-4K is a Chinese camera based on the Novatek NT96660 processor and Omnivision OV4689 CMOS sensor (Note as of Aug 2020 Rove claims this camera uses a SONY IMX335 CMOS sensor. This has not been verified so be careful updating firmware).  While the camera is advertised as a 4K camera, this is not a true statement. 4K cameras must have a native resolution of 3840 × 2160p. The 4MP Omnivision OV4689 CMOS sensor only has a maximum native resolution of 2688 x 1520p.

The 4K option in this camera (2880 x 2160p @ 24fps) is interpolated and does not provide better image quality than the lower resolutions. We suggest running the camera with 2560 x 1440p. While not 4K quality, video quality during the day is good and night quality is above average. The ROVE R2-4K performs similar to other cameras using the NT96660 and OV4689 hardware.

The R2-4K comes with a 2.4″ screen and built in GPS. Build quality is good.  The size of the camera is not the smallest at 76×51×25 mm and not the hanging form factor is not the most discreet. That being said, the camera comes with 2 mounts, a suction and adhesive mount. Both allow the camera to swivel 360° to record interactions at the side windows (i.e. police stops).

The camera comes with G-sensor but does not have a buffered parking mode. The R2-4K also comes with WiFi and supporting apps for Android and iOS. It also uses a 250mAh internal battery rather than a super capacitor. That being said, reliability appears to be above average and there have been some firmware updates for this product.


Like many Chinese dash cams, the ROVE R2-4K is sold under numerous brand names. The most popular is the AZDOME GS63H. This camera is identical to the R2-4K and can be purchased directly from China for $60.


The camera is also sold under the generic names GS63H or RLDV-63H.

Known problems

Overall reliability appears to be above average for the ROVE R2-4K. The most common complaint with the camera is micro-SD card errors. Ensure you are using a legitimate Class 10 MicroSD card for the camera. Samsung is recommended by the manufacturer. SanDisk Ultra is NOT recommended.

Should I Purchase?

The ROVE R2-4K is not a native 4K camera and video quality is on par with other cameras that use the Novatek NT96660 processor and Omnivision OV4689 CMOS sensor. The camera is not the most discreet and the price is high for what you are getting. The internal battery makes this not the ideal camera for hot environments as well.

On the positive side the camera is well built and reliability is above average. If you are considering this camera and want to save a few dollars, the AZDOME GS63H purchased directly from China is equivalent and nearly half the cost.
