Step-by-Step Guide to Using the ROVE Ultimate CPL
INTRODUCTION
Photography and videography enthusiasts understand the value of capturing crystal-clear footage. Whether it's breathtaking landscapes or everyday road trips, having the right accessories can make all the difference. The Circular Polarizer (CPL) filter is one such accessory that can significantly enhance video quality and reduce glare in dash cam footage. In this guide, we will walk you through the installation, adjustment, and maintenance of the ROVE Ultimate CPL Filter for R2-4K PRO, ensuring you capture stunning footage with ease.
Understanding the CPL Filter:
The CPL Filter, also known as the Circular Polarizer filter, is a vital tool in photography and videography. Its
primary function is to reduce glare caused by reflections from your car's dashboard, sunlight, and
headlights. By selectively blocking polarized light waves, the CPL filter improves color and contrast,
resulting in more precise, more vivid footage.
By
recording the moments leading up to a collision and the actions of all parties involved, dash cams provide an
objective account of events, eliminating subjective narratives. This clear documentation simplifies the
claims process, expedites insurance settlements, and assists law enforcement authorities in reconstructing
events and determining fault.

Now that we've covered the important warnings, let's proceed with the step-by-step installation process:
Step 1: Power off Dash Cam
Before you start the installation, turn off your ROVE R2-4K PRO Dash Cam and unplug it to avoid
accidental damage.
Step 2: Clean the Dash Cam Lens
Using a microfiber cleaning cloth, gently remove any dust or smudges from the lens. Ensuring a clean lens is
crucial for obtaining clear and sharp videos.
Step 3: Remove the Lens Cover
Carefully remove the plastic lens cover from the CPL filter. Be cautious not to touch the inside or outside of
the CPL lens to avoid smudging or adding fingerprints, which could result in blurry videos.

Step 4: Hold the Steady Back Side
Hold the CPL filter between your thumb and index finger, with the back side - the side with the threaded
ring - firmly in place. This part of the filter is designed to screw onto the pre-threaded lens of your R2-4K
PRO Dash Cam, ensuring a secure and stable attachment.
With this note, users will have a clear understanding that the front part of the CPL filter is the adjustable
part responsible for reducing glare, while the back side remains steady and serves to attach the filter
securely to the dash cam's lens.

Step 5: Align the Threaded Ring and Start Screwing On
Align the threaded ring of the CPL filter with the pre-threaded lens of the R2-4K PRO Dash Cam. While
securely holding the back side of the filter, start screwing the CPL filter onto the lens in a clockwise
direction until it is firmly attached.

Step 6: Power on Dash Cam
Once the CPL filter is securely attached, power on your R2-4K PRO Dash Cam.
Step 7: Rotate the Front Part
Now that the CPL filter is in place, you can rotate the front part of the filter to adjust the polarization effect.

Step 8: Place a White Piece of Paper
To test the CPL filter's effect, place a small white piece of paper on the dashboard, away from the
windshield, creating a reflection visible in the camera's viewfinder.
Step 9: Adjusting for Glare Reduction - Rotating the Front Part
Focus on the dash cam display and gradually rotate the front side of the CPL filter. Observe for any glare
caused by the reflection from the white paper in the viewfinder. Continue rotating the filter until the glare
is significantly reduced or disappears. Experiment with different angles to find the optimal position that
effectively reduces glare while maintaining image quality.

With this note, users will understand that the white paper reflection is not always entirely avoidable due to
various factors, and the aim is to achieve the best possible reduction based on their specific preferences and
environmental conditions.
Step 10: Test theCPL Filter
Once you have adjusted the CPL filter, remove the white piece of paper. Take a few test recordings in
different lighting conditions to ensure the CPL filter provides the desired glare reduction and enhances
overall video quality.

Why you need to use a CPL filter with your dash cam, and how it can transform your video recording experience.
Reduce Glare, Enhance Clarity:
Glare from your car's dashboard, sunlight, and headlights can be a real challenge when trying to capture
clear footage. The CPL filter acts as a shield against these distracting glares and reflections, allowing your
ROVE R2-4K PRO to deliver clearer, more detailed videos. With the CPL filter, you can say goodbye to
washed-out scenes and enjoy crisp, well-defined images.

Elevate Color Saturation and Contrast:
The CPL filter not only reduces glare but also enhances color saturation and contrast. This means your
videos will boast vibrant and lifelike colors, making your recorded moments even more captivating to
watch. Whether it's the scenic beauty of a countryside drive or the hustle and bustle of a city commute, the
CPL filter ensures your videos stand out with stunning visuals.

Optimal Performance in Any Lighting Conditions:
Driving during bright sunny days or facing challenging lighting conditions can be tricky for any dash cam.
However, with the CPL filter in place, your R2-4K PRO can perform at its best in any situation. Say goodbye
to unclear or overexposed footage, as the CPL filter cuts through the glare and delivers impeccable video
clarity even in adverse lighting.
Unveil Hidden License Plates:
License plate visibility is essential, especially in critical situations. Glare can often obscure license plates,
making it challenging to identify vehicles involved in incidents. The CPL filter helps reveal license plates
with better clarity, providing valuable evidence and peace of mind in case of accidents or emergencies.

Customizable Glare Reduction:
Not all driving environments are the same, and that's where the CPL filter's versatility shines. The front part
of the filter can be easily rotated to adjust the polarization effect according to your specific surroundings.
This customization allows you to fine-tune the glare reduction to your preference, ensuring optimal
performance in various driving conditions.


With the ROVE Ultimate CPL Filter for R2-4K PRO, you have the power to improve the quality of your dash
cam footage significantly. By reducing glare and enhancing color and contrast, this accessory allows you to
capture stunning videos during your everyday drives or memorable road trips. Remember to follow the
installation and maintenance guidelines to maximize the lifespan and efficiency of your CPL filter.
