Installing a small dash cam is a relatively straightforward task, but it's crucial to ensure a proper power connection to avoid damaging the battery. Here is a comprehensive guide on how to install a dash cam while safeguarding your vehicle's battery:

1. Disconnect Vehicle Power: Before beginning the installation, make sure your vehicle is in a stopped state with all power sources turned off. Turn off the engine and remove the key.

2. Gather Required Materials: Ensure you have a copy of your vehicle's electrical wiring diagram to know which power lines to connect. You will also need the following tools and materials:

   - Dash cam and its mounting bracket

   - Screws and fixtures for bracket installation

   - Power cable

   - Wiring tools (e.g., screwdriver, wire stripper, electrical tape)

   - Power detector or voltage meter

3. Position the 4G Wifi Dash Cam: Choose an appropriate location to install the small dash cam, ensuring it doesn't obstruct your line of sight and is easily accessible. Typically, 4G wifi dash cam are installed on the vehicle's front windshield.

4. Connect the Power Cable:

   a. Locate the vehicle's internal fuse box. You can find its location on the vehicle's electrical wiring diagram.

   b. Use a power detector or voltage meter to find a constant power source and a grounding point. A constant power source is one that remains powered even when the vehicle is off, such as a spare power source or interior lighting power.

   c. Connect the power cable to the constant power source and grounding point. Ensure the connections are secure and use electrical tape to insulate them.

   d. Use electrical tape or cable ties to conceal the power cable along the vehicle's internal wiring harness, ensuring a neat installation that doesn't interfere with driving.

5. Connect the Ground Wire: Connect the dash cam's ground wire to a metal part of the vehicle, ensuring it has solid contact with the vehicle's metal frame.

6. Install the Dash Cam: Attach the small dash cam to its mounting bracket and secure the bracket in the chosen location, ensuring it is stable and doesn't wobble.

7. Test the Dash Cam: Reconnect the vehicle's power, start the engine, and test if the dash cam functions correctly. Make sure it records video and saves it to the SD card.

8. Power Management Device (Optional): If you are concerned about the portable dash cam draining the battery during extended parking, consider installing a power management device that can automatically power off the dash cam to prevent battery depletion.

Please note that the installation process may vary depending on the vehicle model, so it's advisable to consult the specific electrical wiring diagram for your vehicle and follow the installation guidelines provided by the manufacturer. If you are unsure about the installation, it's best to seek the assistance of a professional automotive electrical technician to ensure a correct and safe installation.
