If you own a car that you drive infrequently, you may be wondering about the best power option for your dash cam. Two popular choices are OBD (On-Board Diagnostics) connections and battery-powered solutions. In this article, we’ll compare these options, discussing battery drain, installation ease, and reliability to help you make an informed decision.
Before diving into the comparison, let’s briefly explain the two power sources:
Pros:
Drawing power from the car’s electrical system means that the dash cam can run continuously without draining the car’s battery.
It’s particularly advantageous for infrequently used cars, as the dash cam will remain operational even when the vehicle is parked.
Cons:
If the car is left unused for an extended period, there’s a slight risk of draining the vehicle's battery if the dash cam remains powered while the ignition is off.
Pros:
These dash cams can operate independently of the vehicle’s battery, making them a good option for short trips or when you don’t want to rely on the car’s electrical system.
Cons:
The main drawback is battery drain. If the dash cam is not charged regularly, it may not function when you need it.
Additionally, battery life can vary based on usage and settings.
Pros:
Installation is generally straightforward. You simply plug the dash cam into the OBD-II port, and it’s ready to go.
No complex wiring or tools are typically required.
Cons:
Access to the OBD-II port may be limited in some vehicles, requiring careful positioning for optimal use.
Pros:
These can be installed anywhere in the vehicle without needing to connect to the OBD-II port.
This flexibility allows for creative placement to capture the best angles for recording.
Cons:
You will need to ensure that the battery is charged regularly, which can be inconvenient.
Pros:
Generally offers reliable performance, as it draws power directly from the vehicle.
The dash cam can remain operational even when the car is parked, ensuring you have footage in case of an incident.
Cons:
If the vehicle’s battery is weak or if there are electrical issues, the dash cam may not function as intended.
Pros:
They can be very reliable if charged properly, and they won’t interfere with the vehicle’s electrical system.
Cons:
The need for regular charging can lead to missed recordings if the battery runs out unexpectedly.
When deciding between OBD connections and battery-powered solutions for your dash cam, consider your driving habits and preferences:
Ultimately, both options have their advantages and drawbacks. By evaluating your specific needs and how often you use your vehicle, you can make an informed decision that best suits your driving lifestyle.
