Setup Guide
1. Prepare the Dash Cam
Before installation, ensure the dash cam is powered off. Insert a high endurance microSD card (not included) into the designated slot on the side of the main unit. VIOFO industrial high endurance microSD cards (64GB, 128GB, 256GB, or 512GB) are recommended for optimal performance. Attach the static windshield sticker to your windshield first, then apply the 3M adhesive mount of the dash cam onto the static sticker. This prevents adhesive residue on your windshield if you need to remove the dash cam later.
This diagram illustrates the initial preparation steps for the dash cam. It shows how to insert the microSD card into the main unit, attach the Circular Polarizing Lens (CPL) filter to the front camera lens, and apply the static sticker to the windshield before mounting the dash cam.
2. Install the Front Camera
Select a location on your windshield next to the rear-view mirror that does not obstruct your view. Ensure it is within the area covered by your wipers. Clean the surface thoroughly before applying the static sticker and then the dash cam mount.

3. Install the Rear Camera
Mount the rear camera on your rear windshield. The 6-meter rear cable is typically sufficient for most vehicles. Route the cable discreetly along the vehicle's headliner and A-pillars using the provided trim removal tool to tuck the cable under the trim.

4. Power Connection
Connect the car charger to your vehicle's 12V power outlet (cigarette lighter socket) and then connect the Type-C end to the main dash cam unit. The dash cam will automatically power on and begin recording when the vehicle starts.

4. Parking Modes
The A229 Pro offers three parking modes for 24/7 vehicle protection. An optional HK4 ACC hardwire kit (ASIN: B09MRVP2PX) is required for these features.
- Auto Event Detection: Records 15 seconds before and 30 seconds after a detected event (motion or impact).
- Low Bitrate Recording: Continuous recording at a lower bitrate to save SD card space.
- Time Lapse: Records continuously at a low frame rate (e.g., 1, 2, 3, 5, or 10 frames per second).
This image illustrates the three distinct parking modes of the dash cam: Auto Event Detection, which captures events before and after they occur; Low Bitrate Recording for extended continuous surveillance; and Time Lapse Recording for condensed video summaries of long periods.
5. Loop Recording & Emergency Lock
The dash cam features loop recording, automatically overwriting the oldest files when the memory card is full. The built-in G-sensor detects impacts or sudden braking, automatically locking the current video file to prevent it from being overwritten.
This illustration demonstrates the continuous loop recording function, where the dash cam automatically replaces older footage with new. It also highlights the auto emergency lock feature, which protects critical video segments from being overwritten during incidents.
6. Circular Polarizing Lens (CPL)
A CPL filter is included to reduce reflections and glare from the windshield and road surfaces, improving image clarity and contrast, especially in bright conditions.
This image illustrates the benefit of the included CPL filter. It shows a side-by-side comparison of dash cam footage, highlighting how the CPL effectively reduces glare and reflections from the windshield, resulting in clearer video.
