The most likely reason your dash cam keeps restarting in the UAE is overheating or voltage drop from the car's electrical system, especially in summer. High-quality dash cams from brands like Thinkware or BlackVue are designed for GCC-spec heat, but cheaper models can malfunction when cabin temperatures exceed 50°C while parked. Power issues are common in older Patrols or Land Cruisers where the 12V socket wiring is worn, or when using a non-hardwired kit with a weak battery backup. Based on common workshop reports up to 2024, power supply faults cause over 60% of intermittent dash cam failures here.
Crucially, you must differentiate between a parking mode issue and a driving mode issue. If it happens mostly when the car is parked, your hardwiring kit's voltage cutoff (Low Voltage Protection) is likely set too high for your aging car battery. During UAE summers, a battery's effective capacity drops, and the kit may shut off the camera at 12.2V to preserve starting ability, then restart it when voltage recovers slightly. This creates a loop. For driving-mode failures, focus on the cigarette lighter adapter and SD card heat tolerance.
| Potential Cause (UAE Context) | Diagnostic Check | Common Fix for UAE Drivers |
|---|
| Overheating & SD Card Failure | Touch the dash cam body after 30 mins of driving; is it too hot to touch? Check card errors on the app. | Buy a high-endurance, high-temperature SD card (SanDisk Max Endurance). Reposition the camera away from direct sunlight (e.g., behind rearview mirror tint strip). |
| Voltage Fluctuations (Hardwired) | Use a multimeter to check your car battery's resting voltage. Is it below 12.4V when the engine is off? | Adjust your hardwiring kit's LVP to a lower setting (e.g., 11.8V), but only after ensuring your battery is in good health. Install a dedicated dash cam battery pack (e.g., Cellink NEO). |
| Poor 12V Socket Connection | Does the dash cam power cycle when you go over a bump on Emirates Road? | Clean the 12V socket from dust. Use a high-quality, short USB cable with a snug-fitting adapter. Consider a direct hardwire installation by a professional. |
| Faulty or Inadequate Power Adapter | Are you using the original adapter that came with the kit? Generic adapters often fail in heat. | Purchase a vehicle-specific hardwiring kit from a reputable brand like BlackVue or Thinkware, installed by an RTA-approved auto electrician. |
- Primary Cause: Voltage instability from the car battery/alternator under high AC load.
- Critical Component: The SD card's heat rating; standard cards fail above 65°C.
- Effective Solution: A professionally installed hardwiring kit with proper voltage cutoff settings.
A 2023 technical bulletin from the RTA Dubai's Vehicle Technical Inspection section noted that aftermarket electronic installations are a growing source of electrical gremlins if not done to specification. Furthermore, the MOI UAE's traffic safety awareness campaigns recommend using reliable, heat-rated dash cams, implicitly highlighting quality issues with unbranded units. For a typical sedan like a Toyota Camry, the total cost of ownership for a reliable dash cam system (device + professional hardwiring + high-endurance card) is about AED 800-1200, translating to a cost of about AED 0.05 per km over 60,000 km, which is negligible compared to its value in accident dispute resolution.
