Setup Guide
1. Unboxing and Initial Inspection
Upon receiving your Acceo B53P Dash Cam, carefully unbox all components and verify against the "Package Contents" list. Inspect for any visible damage.
2. Micro SD Card Installation
Insert a Class 10 Micro SD card (16GB to 128GB, not included unless purchased optionally) into the TF card slot on the side of the DVR unit. Ensure it is inserted correctly until it clicks into place.

3. Mounting the Dash Cam
- Clean the area on your windshield where you intend to mount the dash cam.
- Attach the electrostatic sticker to the cleaned area.
- Peel off the protective film from the adhesive mount on the dash cam.
- Firmly press the dash cam onto the electrostatic sticker.

4. Power Connection
Connect the provided power charger to the Type-C port on the dash cam and plug the other end into your car's cigarette lighter socket. The dash cam will power on automatically when the car starts.
5. GPS Module Connection (External GPS)
Connect the external GPS module to the dash cam. Upon successful positioning, the GPS icon on the dash cam screen will change from red to green. This ensures accurate location and speed logging.

6. Rear Camera Installation (Optional)
If you have the optional rear camera, connect it to the AV port on the main DVR unit. The rear camera can be installed on the rear windshield to record the rear view or on the front windshield to record the car's interior.
Warning: Due to varying car models, professional installation is recommended for the rear camera to prevent damage to the recorder. This method is for reference only.

7. Wi-Fi Connection and App Setup
- Download and install the "Viidure" app on your Android smartphone or iPhone.
- On your phone, go to Wi-Fi settings and connect to the dash cam's Wi-Fi network (e.g., "OK309Cam-FFKIA202").
- Open the Viidure app. You can now watch real-time video, control the DVR, take photos, play back recorded videos, and adjust settings via the app.


Operating Instructions
1. Power On/Off
The dash cam will automatically power on and begin recording when your vehicle's ignition is turned on. It will power off automatically when the ignition is turned off.
To manually power on/off, long press the power button (refer to product display image for button location).
2. Recording Modes
- Normal Recording: Continuous recording while driving.
- Dual Lens Recording: If a rear camera is connected, both front and rear views are recorded simultaneously.

3. Loop Recording
When this feature is enabled, the memory card will continuously record. Once the card is full, the oldest unlocked video files will be overwritten by new recordings. Important event videos (triggered by G-Sensor or Parking Monitor) are protected from being overwritten.
4. G-Sensor (Gravity Sensor)
The G-Sensor detects sudden impacts or collisions. When triggered, it automatically locks the current video segment, preventing it from being overwritten during loop recording. This ensures critical incident footage is preserved.
5. WDR (Wide Dynamic Range)
WDR technology processes local exposure control, eliminating glare and dimming in challenging lighting conditions, such as strong backlight or tunnels, to ensure clear video quality.
6. Night Vision
The dash cam features Super Night Vision Technology and an F/1.6 aperture lens, allowing it to capture clearer videos and photos even in low-light night conditions.
7. Parking Monitor (24H Monitoring)
For 24-hour parking monitoring, the optional Hardwire Kit is required. If someone hits your car and the G-Sensor is triggered while parked, the DVR will automatically turn on and record the incident.
Hardwire Kit Connection:
- Connect the negative pole (black wire) of the Hardwire Kit to the ground of your car's fuse box.
- For continuous monitoring after parking (24-hour operation), connect the positive pole (red wire) of the Hardwire Kit to the BAT interface of the car fuse box.
- If you prefer the DVR to stop working after parking, connect the positive pole of the Hardwire Kit to the ACC interface of the car fuse box.
Note: The DVR is only compatible with cars that have a 12V power supply. A 24V power supply will damage the motherboard. If your vehicle uses 24V, you must use a 24V to 12V converter (KIT).


Maintenance
1. General Care
- Keep the dash cam clean. Use a soft, dry cloth to wipe the lens and body. Avoid using abrasive cleaners or solvents.
- Ensure the dash cam is securely mounted to prevent it from falling during driving.
- Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods, as this may affect its lifespan.
2. Memory Card Management
- Regularly format your Micro SD card (at least once a month) to maintain optimal recording performance and prevent data corruption. This can usually be done through the dash cam's settings menu or the mobile app.
- Use only high-quality Class 10 Micro SD cards from reputable brands. Low-quality or slow cards can lead to recording errors or device malfunction.
- Replace the Micro SD card if you notice frequent errors or degraded performance.
Troubleshooting
- Dash Cam not powering on:
- Check if the power cable is securely connected to both the dash cam and the car's power outlet.
- Ensure the car's cigarette lighter socket is functioning.
- If using a Hardwire Kit, verify all connections are correct and the car's power supply is 12V.
- Recording errors or freezing:
- Ensure you are using a Class 10 or higher Micro SD card.
- Format the Micro SD card regularly.
- Try a different Micro SD card to rule out card issues.
- Time/Date is incorrect or shifts:
- Ensure the external GPS module is properly connected and has successfully acquired a signal (GPS icon is green). The GPS automatically synchronizes the time.
- If GPS is not used, manually set the time and date through the dash cam's settings or via the connected mobile app.
- Wi-Fi connection issues:
- Ensure the dash cam's Wi-Fi is enabled.
- Check your phone's Wi-Fi settings to ensure it's connected to the dash cam's network.
- Restart both the dash cam and your phone, then try connecting again.
- Rear camera not displaying/recording:
- Verify the rear camera cable is securely connected to the AV port on the main DVR unit.
- Check for any damage to the rear camera cable.
User Tips
- For optimal time synchronization, always ensure your external GPS module is connected and has a strong signal. The dash cam will automatically update its time.
- The rear camera offers versatility: mount it on the rear windshield for external rear view recording, or on the front windshield to monitor the car's interior.
- Utilize the Wi-Fi connectivity and the "Viidure" app to conveniently view live footage, manage recordings, and adjust settings directly from your smartphone.
- The advanced Super Night Vision Technology and F/1.6 aperture are designed to capture clear footage even in challenging low-light conditions, enhancing visibility of details like license plates at night.
- Regularly check your Micro SD card for sufficient space and format it periodically to prevent recording issues.
