• Secure Connections: Ensure all cable connections (to the dash cam, power source, and any rear cameras) are snug and fully seated. Loose connections are a common cause of unexpected shutdowns.
• Power Supply: Verify that your dash cam is receiving adequate power. USB ports in cars or computers often provide only 0.5A, while most dash cams require at least 1.5A. Always use the manufacturer-supplied power adapter (cigarette lighter or hardwire kit) for reliable operation.

5. Review and Refine Camera Settings

Incorrect or outdated settings can prevent your dash cam from capturing the best possible footage or operating efficiently.

Frequency:

• Review: Quarterly, or after a firmware update or any significant temperature change.

Key Settings to Check:

• Recording Resolution & Frame Rate: Ensure it’s set to the highest quality your SD card and storage capacity can comfortably handle (e.g., 1080p at 30fps or 60fps, 2K, 4K).
• Loop Recording: Confirm this essential feature is enabled, allowing the dash cam to continuously record by overwriting the oldest non-locked files.
• G-Sensor Sensitivity: Adjust the G-sensor (impact detection) sensitivity. If it’s too high, it will lock too many unnecessary files due to bumps; if too low, it might miss actual impacts.
• Date and Time: Verify that the date and time are accurate. This is crucial for evidence, and an accurate GPS lock typically updates this automatically.
• Parking Mode Settings: If your dash cam has parking mode, ensure its settings (e.g., motion detection sensitivity, recording duration) are configured to your preference.

6. Protect Your Dash Cam from the Elements

Dash cams are built to withstand car environments, but prolonged exposure to extremes can shorten their lifespan.
