1.3 Initial Setup & Formatting
After installation, perform these initial setup steps:
- Power On: The dash cam will automatically power on when your vehicle starts.
- Format SD Card: It is crucial to format the Micro SD card before first use and periodically thereafter to ensure optimal performance and prevent data corruption. Navigate to the settings menu on the dash cam's 3.0" IPS screen and select the 'Format' option. Confirm to proceed.
- Set Date/Time: Adjust the date and time settings in the menu for accurate timestamping of recordings.
- Connect to App (Optional): Download the 'Viidure' app from your mobile app store. Enable 5.8GHz Wi-Fi on the dash cam via the settings menu and connect your phone to the dash cam's Wi-Fi network (SSID and password displayed on screen). This allows for real-time viewing, downloading, and sharing of footage.
2. Operating Instructions
Understand the various features and how to operate your Pahaa X18 Dash Cam.
2.1 Recording Modes
- Loop Recording: The dash cam continuously records video in segments (e.g., 1, 2, or 3 minutes). When the Micro SD card is full, the oldest unlocked video segments are automatically overwritten by new recordings. This ensures continuous recording without manual intervention.
- G-Sensor (Emergency Recording): The built-in G-sensor detects sudden impacts or abrupt braking. In such events, the current video segment is automatically locked and saved to a protected folder, preventing it from being overwritten by loop recording. The sensitivity of the G-sensor can be adjusted in the settings (High, Middle, Low, or Off).
- 24H Parking Mode: This feature provides continuous surveillance when your vehicle is parked. It requires a hardwire kit (ASIN: B0FCS616L6, sold separately) to ensure constant power. When motion or impact is detected while parked, the dash cam will automatically start recording.

3. Maintenance
Proper maintenance ensures the longevity and optimal performance of your dash cam.
3.1 Cleaning
- Lenses: Regularly clean the front and rear camera lenses with a soft, lint-free cloth to ensure clear video quality. Avoid abrasive materials that could scratch the lenses.
- Screen: Wipe the 3.0" IPS screen with a soft, dry cloth. Do not use liquid cleaners directly on the screen.
- Body: Keep the dash cam body free from dust and debris.
3.2 SD Card Management
- Regular Formatting: To maintain optimal recording performance and prevent potential errors, it is recommended to format the Micro SD card every 2-4 weeks. This clears old, unnecessary files and refreshes the card's file system.
- Card Replacement: Micro SD cards have a limited lifespan due to continuous read/write cycles. If you notice recording issues or error messages, consider replacing the SD card. The Pahaa X18 supports up to 256GB cards.
4. Troubleshooting
Here are solutions to common issues you might encounter with your Pahaa X18 Dash Cam.
- Dash Cam Not Powering On:
- Ensure the car charger is securely plugged into both the dash cam and the vehicle's cigarette lighter socket.
- Check if the vehicle's cigarette lighter socket is receiving power (test with another device).
- Verify the power cable is not damaged. - Recording Issues (e.g., footage failed, not recording):
- Format the Micro SD card regularly (see Maintenance section).
- Ensure the Micro SD card is inserted correctly.
- Use a branded U3 speed class Micro SD card (up to 256GB is supported). Lower speed cards may cause recording failures.
- Check if the card is full and loop recording is enabled. If not, older files might not be overwritten. - Wi-Fi Connectivity Problems:
- Ensure Wi-Fi is enabled on the dash cam via the settings menu.
- Verify you are connecting to the correct Wi-Fi SSID and using the correct password (displayed on the dash cam screen).
- Try restarting both the dash cam and your smartphone. - App Not Connecting or Showing Live View:
- Make sure your phone is connected to the dash cam's Wi-Fi network, not your home Wi-Fi or mobile data.
- Ensure the 'Viidure' app has necessary permissions on your phone.
- Update the app to the latest version. - Poor Night Vision:
- Ensure the camera lenses are clean.
- Verify WDR (Wide Dynamic Range) is enabled in the settings for improved low-light performance. - G-Sensor Too Sensitive/Not Sensitive Enough:
- Adjust the G-sensor sensitivity setting (High, Middle, Low) in the dash cam's menu to suit your driving conditions.
