G-Sensor & Loop Recording
The G-Sensor automatically detects sudden shakes or collisions and locks the current video footage to prevent it from being overwritten. This emergency video is stored in a separate folder. Loop recording ensures continuous recording by automatically overwriting the oldest unlocked footage when the SD card is full, providing seamless video coverage.

24-Hour Parking Mode
With the optional 3-lead hardwire kit (ASIN: B0BGHQN5RP), the dash cam can monitor your vehicle for 24 hours. It offers two parking modes:
- Collision Detection Parking Mode: The dash cam automatically starts recording and locks a 1-minute video upon detecting a collision or impact while parked.
- Time-Lapse Parking Mode: Continuously records at 1 frame per second (1fps) to capture long periods of activity in a condensed video format.

Built-in GPS & Tracking
The integrated GPS module accurately records your vehicle's route and driving speed information. You can review this data by playing back videos through the AZDOME GPS Player software on your computer or via the AZDOME app, providing a detailed record of your journeys.

Ultra Clear Night Vision
Equipped with an F1.8 aperture and Wide Dynamic Range (WDR) technology, the dash cam provides superior night vision capabilities. WDR improves exposure by combining over-exposed and under-exposed images, resulting in clear and detailed recordings even in low-light conditions, ensuring visibility of road conditions at night.

Maintenance
SD Card Management
To ensure continuous and reliable recording, it is recommended to periodically format the Micro SD card. While loop recording overwrites old footage, emergency locked videos are protected and will not be deleted automatically. Over time, these protected videos can fill up the card. To manage storage:
- Regular Formatting: Format the SD card every few weeks or months, depending on usage, to clear all data and maintain optimal performance. This can be done via the dash cam's settings or the AZDOME app.
- Manual Deletion: If you need to delete specific protected videos, you can remove the SD card and delete them using a computer.
Always ensure the dash cam is powered off before inserting or removing the SD card to prevent data corruption.
Troubleshooting
This section addresses common issues you might encounter with your AZDOME M300S dash cam.
| Problem | Possible Cause | Solution |
|---|---|---|
| Dash cam does not power on. | Loose power connection, faulty car charger, vehicle power outlet issue. | Check if the car charger is securely plugged into both the dash cam and the vehicle's power outlet. Test the charger in another vehicle or use a different USB cable/charger if available. Ensure the vehicle's power outlet is functional. |
| Rear camera not detected or not displaying video. | Rear camera cable not fully inserted, damaged cable. | Ensure the rear camera cable is fully and securely plugged into the main dash cam unit. Apply firm pressure until it clicks into place. Inspect the cable for any visible damage. |
| WiFi connection issues with the app. | Interference, app glitch, phone settings. | Ensure you are connecting to the correct dash cam WiFi network. Try restarting both the dash cam and your phone. On your phone, temporarily disable mobile data or other WiFi networks to ensure a direct connection to the dash cam. Some phone OS versions may require you to confirm connection to a network without internet access. |
| Video quality is poor or blurry. | Protective film on lens, dirty lens, incorrect resolution setting. | Remove any protective film from the camera lenses. Clean the lenses with a soft, lint-free cloth. Check the video resolution settings in the app and ensure it is set to 4K for the front camera. |
| SD card full, not recording new videos. | Too many locked/emergency videos, SD card error. | Format the SD card regularly through the dash cam settings or app. If the issue persists, try a different high-endurance Micro SD card (up to 256GB supported). |
