5. Basic Operation
5.1 Power On/Off
The dash cam will automatically power on and begin recording when connected to the car's power supply and the vehicle ignition is turned on. It will power off automatically when the ignition is turned off.
5.2 Recording Modes
The M53 supports continuous loop recording, G-sensor activated emergency recording, and 24-hour parking monitoring.
- Loop Recording: When the SD card is full, the dash cam automatically overwrites the oldest unlocked video files to make space for new recordings. This ensures continuous recording without manual intervention.
- G-Sensor (Emergency Recording): The built-in G-sensor detects sudden shakes or collisions. When triggered, it automatically locks the current video segment, preventing it from being overwritten by loop recording. These locked files serve as crucial evidence in case of an incident.
- 24-Hour Parking Mode: With an optional hardwire kit (not included), the dash cam can monitor your vehicle even when parked. If an impact is detected, it will automatically start recording.

This infographic illustrates how the dash cam automatically manages storage by overwriting the oldest video files when the SD card capacity is reached, ensuring continuous recording. It also provides estimated recording times for different SD card sizes (32GB, 64GB, 128GB, 256GB).
5.3 Video Quality and Features
- 1080P Full HD & 170° Wide Angle: The dash cam records in 1920x1080P at 30 frames per second, capturing clear details. The 170° ultra-wide-angle lens covers up to 6 lanes of traffic, providing a broad view of the road.
- WDR (Wide Dynamic Range): Equipped with WDR technology and an F1.8 large aperture, the dash cam delivers excellent image quality even in challenging lighting conditions, such as strong backlight or low-light environments, enhancing clarity for both day and night recordings.

6. Maintenance and Care
To ensure the longevity and optimal performance of your COOAU Mini Dash Cam M53, consider the following:
- Clean the Lens: Regularly clean the dash cam lens with a soft, lint-free cloth to ensure clear video recordings. Avoid abrasive materials that could scratch the lens.
- SD Card Management: Periodically format your Micro SD card (every 2-4 weeks) to prevent data corruption and ensure smooth loop recording. Back up any important locked videos before formatting.
- Temperature Resistance: The M53 utilizes an upgraded supercapacitor, providing stable operation in extreme temperatures ranging from 14°F to 140°F (-10°C to 60°C). This design enhances safety, energy efficiency, and extends the product's lifespan compared to traditional lithium-ion batteries, avoiding issues like battery expansion in heat or failure in cold.
- Secure Mounting: Ensure the suction cup mount is securely attached to the windshield to prevent the dash cam from falling, especially during temperature fluctuations. Re-attach if it becomes loose.
