- Dash cam footage provides an objective, unbiased account of an incident. It can clearly show who was at fault, what led to the collision, and the sequence of events.
- This is invaluable in cases of hit-and-runs, fraudulent claims, or “crash for cash” scams.
- Faster Claims Processing:
- With clear video evidence, insurance companies can often process claims much more quickly and efficiently, leading to faster payouts for repairs.
- It reduces the reliance on subjective witness statements or police reports alone.
- Protection Against False Accusations:
- If another driver falsely accuses you of an infraction, your dash cam footage can exonerate you, preventing increases in your insurance premiums or legal issues.
- Discount Opportunities:
- Some insurance providers offer discounts to policyholders who use dash cams, recognizing their value in preventing fraud and streamlining claims. It’s worth inquiring with your insurer.
- Documenting Parking Incidents:
- With parking mode enabled, your dash cam can capture hit-and-runs in parking lots, vandalism, or other incidents that occur while your car is unattended. This is especially useful for a wireless dual dash cam, as it covers both front and rear.
Maintenance and Best Practices for Longevity
Like any electronic device in a demanding environment your car’s interior, a dash cam needs a little care to ensure it lasts and performs reliably.
- Regular SD Card Formatting:
- This is arguably the most important maintenance step. Dash cams are constantly writing and overwriting data. Formatting the microSD card every 1-2 months using the dash cam’s own formatting function, not a computer helps maintain its health, prevent file corruption, and ensure smooth recording.
- Always back up any important footage before formatting.
- Use High-Endurance SD Cards:
- Reiterating this point because it’s critical: Standard consumer-grade SD cards are not designed for the continuous write cycles of a dash cam and will fail prematurely. Invest in a high-endurance microSD card from a reputable brand e.g., Samsung PRO Endurance, SanDisk High Endurance. These cost a bit more but will save you headaches in the long run.
- Keep Firmware Updated:
- Check the manufacturer’s website periodically for firmware updates. These updates often include bug fixes, performance improvements, and new features. Follow the update instructions carefully.
- Clean the Lens:
- Just like your car’s windshield, the dash cam lens can get dirty. Gently wipe the lens with a soft, lint-free cloth to ensure clear, unobstructed footage. Avoid abrasive cleaners.
- Check Cable Connections:
- Periodically check that all power cables and if applicable rear camera cables are securely plugged in and haven’t come loose due to vibrations.
- Manage Temperature Extremes:
- While supercapacitors help, prolonged exposure to extreme heat e.g., parking in direct summer sun for hours can still stress electronics. If possible, park in the shade.
- In extreme cold, ensure the camera powers on and functions correctly once the car warms up.
- Back Up Important Footage:
- Develop a habit of regularly downloading any important footage e.g., scenic drives, close calls, or actual incidents to your phone, computer, or cloud storage. Don’t rely solely on the SD card, especially before formatting.
By adhering to these best practices, you can significantly extend the life of your wireless dual dash cam and ensure it’s ready to perform when you need it most.
