2. Safety Features
The DDPAI DC003 Hardwire Kit is designed with multiple protection mechanisms to ensure safe and reliable operation for both your dash cam and vehicle's electrical system.

- Low Voltage Protection: Prevents excessive discharge of your vehicle's battery. The kit will cut power to the dash cam if the voltage drops below 11.8V (for 12V systems) or 23.6V (for 24V systems).
- Overcurrent Protection: Safeguards against excessive current flow.
- Short-Circuit Protection: Protects against damage from short circuits.
- Overload Protection: Prevents damage due to excessive power draw.
- Reverse Connection Protection: Ensures proper functionality even if power connections are accidentally reversed.
3. Installation Guide
The DDPAI DC003 Hardwire Kit offers two primary installation methods: via the OBD interface for a plug-and-play experience or via the fuse box for a more integrated setup.
3.1. OBD Interface Installation (Recommended for Ease)
This method provides a non-destructive, plug-and-play installation, ensuring a stable connection without requiring complex wiring or disassembly of vehicle components.

- Locate your vehicle's OBD-II port, typically found under the dashboard on the driver's side.
- Connect the OBD interface of the hardwire kit directly into the vehicle's OBD-II port.
- Route the Type-C cable to your DDPAI dash cam, ensuring it is neatly tucked away and does not obstruct driving.
- Connect the Type-C end to your dash cam.


New Energy Vehicles
The OBD interface installation is also available for New Energy Vehicles, enabling parking monitoring. However, it is invalid for Tesla, LI, and Cayenne models.

3.2. Fuse Box Interface Installation
This method requires disassembly and more complex wiring. It is recommended for users comfortable with vehicle electrical systems or professional installation.
- Locate your vehicle's fuse box.
- Identify a constant power fuse (B+) and an accessory power fuse (ACC) that are suitable for tapping.
- Connect the red wire (B+) of the hardwire kit to the constant power fuse using a fuse tap.
- Connect the yellow wire (ACC) of the hardwire kit to the accessory power fuse using a fuse tap.
- Connect the black wire (GND) to a metal part of the vehicle chassis for grounding.
- Route the Type-C cable to your DDPAI dash cam and connect it.
4. Operating Instructions
Once the hardwire kit is correctly installed and connected to your DDPAI dash cam, it enables continuous power supply and advanced parking surveillance features.
4.1. 24-Hour Parking Monitor
The hardwire kit provides constant power to your dash cam, allowing it to record continuously even when the vehicle is parked and the ignition is off. This feature is crucial for monitoring your vehicle against vandalism or hit-and-runs.
4.2. Time-Lapse Recording
For extended parking surveillance, the kit supports time-lapse recording, which captures footage at a lower frame rate to save storage space while still providing comprehensive coverage.
4.3. IPS Power Management Technology
Integrated Power Management System (IPS) ensures efficient power usage and protects your vehicle's battery from draining completely, thanks to the built-in low voltage protection.

5. Maintenance
The DDPAI DC003 Hardwire Kit is designed for durability and requires minimal maintenance. Follow these guidelines to ensure optimal performance:
- Regular Inspection: Periodically check all connections (OBD port or fuse box, and Type-C connection to the dash cam) to ensure they are secure and free from corrosion or damage.
- Cable Management: Ensure all cables are neatly routed and secured to prevent them from interfering with vehicle operation or becoming damaged.
- Cleanliness: Keep the hardwire kit and its connections free from dust and debris.
- Avoid Extreme Conditions: While designed for automotive use, avoid exposing the kit to extreme temperatures or moisture beyond typical vehicle environments.
6. Troubleshooting
If you encounter issues with your DDPAI DC003 Hardwire Kit, refer to the following troubleshooting steps:
6.1. Dash Cam Not Receiving Power
- Check Connections: Ensure the hardwire kit is securely plugged into the vehicle's power source (OBD port or fuse box) and the Type-C cable is firmly connected to the dash cam.
- Verify Vehicle Power: Confirm that your vehicle's battery has sufficient charge. The low voltage protection feature will prevent the dash cam from drawing power if the battery voltage is too low.
- Fuse Box Installation: If using the fuse box method, check the fuses you tapped into and the fuse within the hardwire kit itself (if applicable) for continuity. Replace any blown fuses.
- OBD Port Functionality: If using the OBD method, ensure your vehicle's OBD-II port is functional.
6.2. Parking Monitor Not Working
- Dash Cam Settings: Ensure that the 24-hour parking monitor or time-lapse recording feature is enabled in your DDPAI dash cam's settings.
- Power Source: Verify that the hardwire kit is connected to a constant power source (B+ wire for fuse box installation) that remains active when the ignition is off.
- Low Voltage Protection: If the vehicle battery voltage drops below the set threshold (11.8V/23.6V), the parking monitor will cease operation to protect the battery. Charge your vehicle's battery if necessary.
6.3. Intermittent Power
- Loose Connections: Re-check all connections for tightness. Vibrations during driving can sometimes loosen connections.
- Damaged Cable: Inspect the Type-C cable and the hardwire kit's main cable for any visible signs of damage (fraying, cuts). Replace if damaged.
