Frequently Asked Questions About Dash Cams

Yes, most dash cams come with built-in microphones and support audio recording. You can toggle audio recording on or off in the dash cam settings.

Recording time depends on the resolution, bitrate, and size of the storage used. A 128GB microSD card typically holds about 10–12 hours of 4K video in loop mode before overwriting the oldest files.

The G-sensor detects sudden movements or impacts and automatically locks the current recording, preventing it from being overwritten. This is crucial in the event of an accident.

Loop recording ensures that once the storage is full, the dash cam will automatically overwrite the oldest footage, except for protected files like emergency events.

A dash cam should not become extremely hot as described. It is normal for the device to feel slightly warm during operation—especially in hot climates—but excessive heat may indicate an issue with the power wiring or installation.

Please review the following points carefully:

1. Check Hardwire Kit Installation (If Connected to Fuse Box)

If your dash cam is connected using a hardwire kit, verify that the wiring is correct:

• Ground Wire (GND) must be securely connected to a clean metal bolt attached to the vehicle chassis.
• ACC Wire must be connected to a fuse that provides power only when the ignition is ON.
• BAT / B+ Wire must be connected to a fuse that provides constant power, even when the vehicle is OFF (used for parking mode).

Incorrect wiring can cause improper power flow, continuous current draw, or abnormal heat generation.

Please refer to the installation manual included with your dash cam to confirm proper wiring configuration.

2. Inspect the Hidden Wiring Behind Panels

• Ensure that wires routed behind interior trims or panels are not pinched, cut, scraped, or compressed.
• Damaged insulation or contact with sharp metal edges can create partial short circuits, which may lead to overheating.

Additional Important Notes

• Dash cams that use a supercapacitor (instead of lithium batteries) are designed to withstand higher temperatures and are generally safer in hot environments.
• However, the device should not become excessively hot to the touch.
• If the issue persists after checking the wiring, disconnect the dash cam and contact technical support for further inspection.

Under normal conditions, a dash cam should not drain your car battery if it is installed and configured correctly.
In most cases, battery drain is caused by incorrect wiring or improper voltage protection settings.

Most dash cams connected via a hardwire kit (fuse box connection) or through the OBD port include a built-in battery protection system. This system continuously monitors your vehicle’s battery voltage and automatically shuts off the camera when the voltage drops below a user-defined threshold.

How Does Battery Protection Work?

When properly installed:

• The dash cam constantly monitors the vehicle’s battery voltage.
• Inside the camera settings, you can select a voltage cutoff level, such as:
  12.0V, 11.8V, 11.6V, or 11.0V (varies by model).
• Once the battery voltage drops to the selected threshold, the camera will automatically power off to prevent excessive battery drain

If configured correctly, the camera should not fully discharge your battery.

Most Common Cause of Battery Drain

In most cases, the issue is caused by:

• Connecting wires to the wrong fuse slots
• Incorrectly wiring the ACC wire and the constant power (B+) wire

If the ACC wire is connected incorrectly, the dash cam may not detect when the vehicle is turned off. As a result, the camera may assume the engine is still running and continue operating normally—leading to continuous power draw and battery drain.

What Should You Check?

1. Verify correct wiring:

• ACC wire must be connected to a fuse that only receives power when the ignition is ON.
• BAT or B+ wire must be connected to a fuse with constant power (even when the vehicle is OFF).
• Ground wire must be securely attached to clean, bare metal on the vehicle chassis.

2. Check the voltage cutoff setting in the dash cam menu and ensure it is set to a safe level.

3. Review the installation manual specific to your dash cam model for the correct fuse connection diagram.

Important Note

If your vehicle battery is old or weak, it may drain faster than normal—even if the dash cam is installed correctly. In that case, it is recommended to test or replace the battery.
