Setup and Installation

It is recommended to consult a professional for installation if you are unfamiliar with motorcycle electrical systems. Ensure the motorcycle is turned off and the battery is disconnected before beginning installation.
1. Main Unit Placement
The main DVR unit is compact and designed to fit discreetly under your seat or in another secure, protected location. Avoid areas exposed to extreme heat or direct impact.

2. Wiring Connection
The dash cam requires connection to your motorcycle's battery (B+) for constant power and an ACC (Accessory) power source that turns on/off with the ignition. The black wire connects to the negative terminal (GND) of the battery.

4. SD Card Installation
Insert a microSD card (up to 128GB, not included) into the main DVR unit. Ensure the card is correctly oriented before insertion. The device will automatically format the card upon first use or if a new card is detected.
5. App Connection (Wi-Fi)
Download the dedicated app from your mobile app store. Turn on the dash cam, enable Wi-Fi on your smartphone, and connect to the dash cam's Wi-Fi network. The default password is typically provided in the manual or on the device itself. Once connected, you can access live view, playback, and settings.

Operating Instructions
1. Automatic Recording
The dash cam automatically starts recording when the motorcycle ignition is turned on (via ACC power) and stops when the ignition is turned off. This ensures that every ride is captured without manual intervention.
2. Dual Channel 1080p Recording
The front and rear cameras simultaneously record in 1080p resolution, providing a comprehensive view of your surroundings. The 160° ultra-wide-angle lenses minimize blind spots.

3. Loop Recording
The dash cam utilizes loop recording, continuously recording and overwriting the oldest files when the microSD card is full. This ensures uninterrupted recording without the need to manually delete files. Recording length can be adjusted via the app (e.g., 1/3/5 minutes).
4. Emergency Recording (G-Sensor)
In the event of a collision or sudden vibration, the built-in G-sensor automatically triggers emergency recording. This locks the current footage to prevent it from being overwritten, providing crucial evidence. Sensitivity can be adjusted through the app. For theft or vandalism, it records a 10-15 second protected video.

5. Night Vision
The dash cam is equipped with night vision functionality, allowing it to capture clear footage in low-light or nighttime environments, enhancing safety during night rides.

6. Wi-Fi and App Control
Connect your smartphone to the dash cam via Wi-Fi to access the dedicated app. The app allows for real-time viewing of footage, playback of recorded videos, downloading files to your phone, and adjusting various settings without needing a cumbersome screen on the dash cam itself.
Maintenance
1. SD Card Management
Due to loop recording, the microSD card will automatically manage storage by overwriting older files. It is recommended to periodically back up important footage to your computer or cloud storage. Format the SD card every few months to maintain optimal performance and prevent data corruption.
2. Cleaning
Wipe the camera lenses and main unit with a soft, damp cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive materials that could damage the device. Ensure all connections are dry before operating the dash cam after cleaning.
Troubleshooting
If you encounter any issues with your NINEYIN Motorcycle Dash Cam, please refer to the following common solutions:
- No Power: Ensure all power connections (B+, ACC, GND) are secure and correctly wired. Check the motorcycle's fuse box for any blown fuses.
- Wi-Fi Connection Issues: Verify that the dash cam is powered on and its Wi-Fi is active. Ensure your smartphone's Wi-Fi is enabled and connected to the correct dash cam network. Try restarting both the dash cam and your phone.
- SD Card Not Recognized/Recording Errors: Ensure the microSD card is inserted correctly. Try formatting the card via the app. If issues persist, try a different, high-quality microSD card (Class 10 or higher recommended).
