Which 5 functions of the driving recorder dashcam need to be setting

1. Gravity Sensor (Collision Detection)

Function: Detects vehicle vibrations or collisions, automatically locking the current video as "emergency recording" to prevent it from being overwritten by loop recording.
Key Setup Points - Sensitivity Adjustment:

• Low Sensitivity: Suitable for urban commuting (filters minor bumps like speed bumps) to avoid frequent false triggers.
• Medium/High Sensitivity: Ideal for high-speed driving, complex road conditions, or areas prone to scratches (e.g., parking lots) to ensure accident videos are saved.
  Tip: Start with "Medium" sensitivity initially, as overly high sensitivity may lock normal driving videos (e.g., over potholes). Adjust based on real-world usage.

2. Resolution and Frame Rate Settings

Function: Determines video clarity and smoothness, requiring a balance between image quality and storage space.

H.265 Encoding: If supported, enable this to reduce storage usage by ~50% (e.g., 4K videos from 15GB/hour to 7.5GB). Ensure playback software compatibility.

3. Night Vision Mode (Including WDR/HDR)

Function: Optimizes imaging in low-light conditions, preventing overexposure in bright areas or underexposure in dark areas.
Setup Strategies:

• Auto Mode: Most models default to "Auto Night Vision," switching based on light sensors. If night performance is poor, manually enable "Night Vision Enhancement" or "WDR (Wide Dynamic Range)."
• Infrared Fill Light: Some models have IR lights for pitch-black environments (e.g., underground garages). Adjust the lens angle to avoid windshield reflections.

4. Loop Recording (Including Emergency Lock, Time-Lapse, and Parking Monitoring)

Core Features:

• Loop Recording Duration: Set single-segment video length (1/3/5 minutes). 3 minutes is recommended (balances file fragmentation and recovery; too long time may cause  freezing and file corruption).
• Emergency Recording Lock: Ensure "Emergency Videos" are stored in a separate folder to prevent overwriting by normal loop recordings.
• Time-Lapse Recording: Ideal for parking monitoring, recording at "1 frame per second" to reduce power consumption (~1/10 of normal recording). A 128GB card can store ~15 days of footage. Pair with gravity sensor for emergency HD recording.
• Parking Monitoring:
  • Hardwiring: Use a voltage step-down cable connected to the car’s constant power (fuse box) instead of ACC to avoid power cutoff when the engine is off.
  • Duration: Limit to 24 hours to prevent draining the car battery (a typical 60Ah battery can power a dashcam ~500mW for ~120 hours).

5. Disabling Audio Recording

Privacy and Legal Considerations:

• When to Disable: For private conversations (e.g., business or family discussions) or in regions where unauthorized recording is illegal (e.g., Germany, South Korea).
• Evidence Trade-off: Keeping audio on can provide supplementary evidence (e.g., verbal disputes during accidents), but inform passengers beforehand where required by law.
• How to Disable: Most models allow turning off the microphone in "Settings > Audio." A "mute" icon may appear on the screen; some high-end models let you disable audio while keeping video recording on.

Additional Considerations for Different Users

• Ordinary Car Owners: Focus on medium sensitivity gravity sensor, 1080P@30fps, auto night vision, 3-minute loop recording, and disable audio (if needed).
• Ride-Hailing Drivers: Prioritize high sensitivity, 2K/4K resolution, longer loop recording (5 minutes), and enable audio (with passenger notification).
• Frequent Night Drivers: Enable WDR/HDR night vision, higher frame rates (e.g., 1080P@60fps), and ensure parking monitoring is hardwired.

By tailoring these settings to your needs, you can ensure your dashcam captures clear, reliable evidence while respecting privacy and optimizing performance. Regularly check settings (e.g., monthly) and format the storage card to maintain reliability.
