A dual dash cam setup provides comprehensive video coverage of the road, but ensuring continuous power without draining your car battery can be a challenge. Utilizing the OBD2 port with the right adapter offers a solution for powering your dual dash cam while parked. This article explores various methods for powering your dual dash cam via the OBD2 port, focusing on safety and efficiency.
Powering Your Dual Dash Cam via OBD2
The OBD2 port, primarily used for vehicle diagnostics, can also serve as a power source for your dual dash cam. Using a dedicated OBD2 to dual USB adapter allows you to power your cameras without occupying the cigarette lighter socket. These adapters often feature built-in voltage cutoff switches to prevent battery drain. When the battery voltage drops below a preset threshold (typically around 11.6 volts), the adapter cuts off power to the dash cam, ensuring your car can still start.
Choosing the Right OBD2 Adapter
Several OBD2 adapters are available on Amazon and other retailers. Look for adapters specifically designed for dash cams with features like:
- Dual USB Ports: Ensure the adapter has two USB ports to power both front and rear cameras.
- Low Voltage Cutoff: This crucial feature protects your car battery from excessive drain.
- Sufficient Amperage: Verify the adapter provides enough power for your specific dual dash cam model (most dual dash cams require 2 amps or less). The OBD2 port itself is typically rated for up to 4 amps.
Alternative Powering Methods with OBD2 Integration
If your cigarette lighter socket is only active when the engine is on, you can combine methods. Use the cigarette lighter socket while driving and switch to an OBD2 adapter with a low voltage cutoff when parked for parking mode recording. This ensures continuous power to your dash cam without risking a dead battery. You can easily switch between power sources by simply plugging and unplugging the adapters. This allows you to utilize the OBD2 port for its intended diagnostic purpose when needed.
Conclusion
Powering your dual dash cam through the OBD2 port offers a convenient and safe solution for continuous recording. Utilizing a dedicated OBD2 adapter with a low voltage cutoff safeguards your car battery while ensuring your dash cam captures crucial footage even when parked. Selecting the right adapter with sufficient power and safety features will provide reliable performance and peace of mind.
