4. Installation Guide
4.1 Mounting the Dash Cam
Front Dash Cam:
- Choose a location on your windshield that does not obstruct your view, typically behind the rearview mirror.
- Clean the mounting area thoroughly.
- Attach the dash cam to the windshield using the provided adhesive mount or suction cup. Ensure it is securely fixed.
Rear Camera:
- Mount the rear camera on the rear windshield or license plate area.
- Route the cable to the front dash cam, ensuring it does not interfere with vehicle operations.
4.2 Power Connection
Standard Power (Car Charger):
- Connect the provided car charger to your vehicle's cigarette lighter socket.
- Plug the other end into the dash cam's power input. The dash cam will power on and off with your vehicle's ignition.
Buck Line Installation (for 24-Hour Parking Monitoring):
To enable 24-hour parking monitoring, a Buck Line (hardwire kit) is required. This allows the dash cam to draw power directly from the car battery even when the engine is off. If you purchased the option with a Buck Line, follow these instructions:
- Connect the Negative Wire (Black): Connect the black wire of the Buck Line to a metal part of the car chassis (ground).
- Connect the ACC Wire (Red): Connect the red wire of the Buck Line to a fuse in your car's fuse box that is only powered when the ignition is on (ACC). This allows the dash cam to detect when the car is running.
- Connect the BAT Wire (Yellow): Connect the yellow wire of the Buck Line to a fuse in your car's fuse box that has constant power, even when the ignition is off (BAT). This provides continuous power for parking monitoring.
Important: If you want to stop monitoring after parking, the DVR does not work. After parking, connect the positive pole of the buck line to the fuse box ACC interface.

5. Operating Instructions
5.1 Initial Setup
- Insert SD Card: Ensure a Class 10 or higher Micro SD card (up to 128GB) is inserted into the dash cam before powering on.
- Power On/Off: The dash cam will automatically power on when the vehicle starts and power off when the ignition is turned off (if connected via car charger or properly installed Buck Line).
5.2 Recording Modes
- Dual Recording (Front 4K + Rear 1080P): The dash cam records simultaneously from both front and rear cameras, providing comprehensive video evidence.
- Loop Recording: When the memory card is full, new recordings will automatically overwrite the oldest unlocked footage. Emergency locked videos are protected from being overwritten.
- Emergency Recording (G-Sensor): In the event of a sudden impact or collision, the built-in G-sensor will trigger emergency recording, automatically saving and locking the current video segment to prevent it from being overwritten.


5.3 Night Vision
The dash cam features Super Night Vision, utilizing an F2.0 wide aperture and a 6-Glass wide-angle lens. This technology enhances image clarity and detail capture, such as license plates, even in low-light conditions.

5.4 24-Hour Parking Monitor
When connected via a Buck Line, the 24-hour parking monitor provides continuous surveillance. If an impact is detected by the G-sensor while your vehicle is parked, the dash cam will automatically turn on, record a 1-minute video, and lock it to prevent overwriting.

5.5 GPS Tracking
The built-in GPS logger records your driving route, speed, and other relevant data. This information can be reviewed using the dedicated Viidure GPS player software on your computer.

5.6 WiFi Connectivity and App Control (Viidure App)
The Kocam S5 Pro features 2.4GHz WiFi for seamless connection to your smartphone via the Viidure app (available for iOS and Android). This allows for:
- Real-time Video: View live footage from your dash cam on your phone.
- Video Playback: Replay recorded videos directly from the dash cam.
- Download & Share: Download videos to your phone and share them on social media or with family.
- Settings Adjustment: Configure dash cam settings through the app.
The 2.4GHz WiFi offers a higher data rate, is less prone to interference, and significantly improves the connection between the dash cam and the application, enabling easier 4K video streaming and data transfer up to 10MB/s.


6. Maintenance
6.1 Memory Card Management
- Regular Formatting: To ensure optimal performance and prevent data corruption, it is recommended to format the Micro SD card every 2-4 weeks. This can usually be done through the dash cam's settings or the Viidure app.
- Card Replacement: Memory cards have a limited lifespan. If you experience frequent recording errors or data loss, consider replacing the SD card.
6.2 Cleaning
- Lens: Gently wipe the camera lenses with a soft, lint-free cloth to remove dust or smudges. Avoid abrasive materials that could scratch the lens.
- Screen: Clean the display screen with a soft, dry cloth.
- Body: Wipe the dash cam body with a slightly damp cloth if needed, ensuring no moisture enters ports.
6.3 Environmental Care
- Avoid exposing the dash cam to extreme temperatures (very hot or very cold) for extended periods, as this can affect battery life and component performance.
- Keep the device away from strong magnetic fields.
7. Troubleshooting
If you encounter issues with your Kocam S5 Pro dash cam, refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Dash cam not powering on | Check car charger connection. Ensure vehicle's cigarette lighter socket is functional. If using Buck Line, verify correct installation and fuse connections. |
| Recording not starting or stopping unexpectedly | Ensure Micro SD card is inserted correctly and is Class 10 or higher. Format the SD card. Check if the card is full (loop recording should manage this, but a faulty card might not). |
