- Mount the rear camera on the rear windshield, ensuring it has a clear view.
3. Power Connection

- Plug the car charger into your vehicle's 12V power outlet (cigarette lighter socket).
- For 24-hour parking monitoring, it is recommended to use the provided Hardwire Kit (OBD interface) which connects directly to your car's fuse box and offers low-voltage protection to prevent battery drain.
4. Insert Micro SD Card
- Ensure the dash cam is powered off.
- Insert the 128GB Micro SD card into the designated slot until it clicks.

Operating Instructions
Power On/Off
The dash cam will automatically power on and begin recording when your vehicle's ignition is turned on (if connected to a switched power source). It will power off automatically when the ignition is turned off.
Quad-Channel Recording
The D90-4CH-RGW records simultaneously from four channels: front, rear, and two interior cabin cameras (left and right). All cameras record in Full HD 1080P resolution.

The two interior cabin cameras can be rotated 180 degrees horizontally and 360 degrees vertically, allowing flexible adjustment to cover various angles, including side windows for potential police encounters or passenger monitoring.

Loop Recording
The dash cam continuously records video in short segments (e.g., 1, 3, or 5 minutes). When the memory card reaches its full capacity, the oldest unlocked footage is automatically overwritten to ensure continuous recording. This feature prevents the memory card from filling up and stopping recording.

G-Sensor (Emergency Accident Lock)
The built-in G-sensor detects sudden impacts or collisions. When an event is detected, the current video segment is automatically locked and saved to a protected folder on the Micro SD card. This prevents the footage from being overwritten by loop recording, preserving it as crucial evidence.

24-Hour Parking Mode with Microwave Radar Motion Detection
When properly connected via the Hardwire Kit, the dash cam can monitor your vehicle 24/7. The Microwave Radar Motion Detection feature automatically triggers recording when someone approaches your vehicle, even if there's no physical impact. This provides continuous surveillance and protection against vandalism or theft.

Built-in GPS
The integrated GPS module records precise location, speed (KMH/MPH), and time data. This information can be viewed on a map when reviewing footage using the dedicated PC viewer software or mobile app, providing a complete record of your journey.

Built-in 2.4G / 5G Dual Band Wi-Fi
Connect your smartphone to the dash cam via the free PRUVEEO app using the built-in dual-band Wi-Fi (2.4GHz/5GHz). This allows for faster transfer speeds, live view, configuration adjustments, file browsing, video download, and sharing directly from your phone.

Maintenance
- Memory Card Care: Regularly format the Micro SD card (at least once a month) to prevent data corruption and ensure smooth operation. Use only high-quality, high-endurance Micro SD cards, preferably the one provided by PRUVEEO, as standard Class 10 cards may not meet the demands of 4-channel recording.
- Cleaning: Use a soft, dry cloth to clean the camera lenses and the dash cam screen. Avoid using abrasive cleaners or solvents that could damage the device.
- Firmware Updates: Check the PRUVEEO official website or app periodically for firmware updates. Keeping your dash cam's firmware up-to-date can improve performance and add new features.
