Set up the 70Mai Dash Cam with a secure mount, suitable storage, tidy power routing, and a short recording test before relying on it for daily driving.
[note] Mounts, menus, storage limits, available settings, and parking features can vary between 70Mai Dash Cam models and accessory packages. [/note]Before You Start
[checklist] * 70Mai Dash Cam and its mounting hardware are ready * Compatible microSD card is available if your model uses removable storage * Original or compatible power cable and car charger are ready * Windshield is clean and dry * Microfiber cloth is available * 70mai app is installed on your phone if app setup is supported [/checklist]For models that use a microSD card, choose a card that meets the requirements of your specific dash cam. Class 10 or higher is commonly required, and a high-endurance card can be useful for continuous recording.
[tip] Park in a shaded, stationary location while mounting the camera and routing the cable. [/tip]Check the Box
Package contents vary, but the setup may include:
- 70Mai Dash Cam unit.
- Adhesive or suction mounting hardware, depending on the model.
- Power cable.
- Car charger or 12V socket adapter.
- Electrostatic sticker or adhesive pad on supported packages.
- Trim or pry tool for cable routing on some packages.
- Optional hardwire kit if purchased separately.
Before installation, check that the camera body has no visible damage or loose parts, the lens is clean and uncovered, and the power connectors fit securely. Resolve missing or damaged parts before mounting the camera.
Choose the Mounting Position
A good position gives the camera a clear forward view without interfering with normal driving visibility or vehicle equipment.
[dosdonts] Do: Mount the camera high on the windshield near the rearview mirror Do: Position it near the center or slightly toward the passenger side when suitable Do: Keep it outside the driver's main line of sight Do: Check that the road ahead is clearly visible before attaching the mount Dont: Block built-in vehicle cameras or sensors Dont: Place the camera where it obstructs traffic lights, signs, or pedestrians Dont: Mount over an area that prevents the adhesive or suction mount from sitting securely Dont: Route equipment where it could interfere with an airbag deployment path [/dosdonts]Heavy tint, windshield edge films, or textured dot-matrix areas may reduce mounting stability or affect the camera view. Local windshield-mounting rules may also vary.
Check the Position Before Sticking
Sit in the normal driving position and hold the camera with its mount against the intended location. Check that it sees the road ahead with only a small amount of the vehicle at the bottom of the view.
The camera should remain reachable when necessary without becoming a distraction. A position behind or close to the rearview mirror often keeps it less noticeable from the driver's seat.
Prepare the Windshield and Mount
Adhesive Mount
- Remove the protective film from the adhesive surface.
- Align the mount carefully before making contact.
- Press it firmly against the mounting surface for about 30–60 seconds.
Suction Mount
- Place the suction cup flat against the clean glass.
- Press and lock the mounting mechanism if the mount uses a locking lever.
Install and Format the microSD Card
If your model uses a removable memory card, install it before normal recording.
[step] 1. Locate the microSD card slot on the dash cam 2. Check the card orientation shown by the slot markings 3. Insert the card gently until it locks into place 4. Power the dash cam on 5. Open the storage, memory card, or format control available on the camera or app 6. Choose the format option and confirm [/step] [warning] Formatting erases the files stored on the card. Save any important recordings before formatting. [/warning]Do not force a card that does not slide in normally. Recheck its orientation first. Formatting the card in the dash cam helps prepare it for the recording format used by the device.
Connect Power and Route the Cable
[step] 1. Connect the small end of the power cable to the dash cam 2. Route the cable along the upper edge of the windshield 3. Continue down the side of the cabin toward the dashboard 4. Connect the cable to the car charger 5. Plug the charger into the vehicle's 12V socket 6. Start the vehicle or switch the socket on and confirm that the dash cam receives power [/step]A socket that switches with the ignition normally allows the camera to start when vehicle power becomes available.
Keep the Cable Tidy
- Tuck the cable carefully along the headliner where appropriate.
- Route it down the A-pillar without crossing an airbag deployment path.
- Continue along the dashboard or glovebox area toward the power socket.
- Use supplied clips or cable guides if available.
Optional Parking Power
Some 70Mai parking-surveillance functions require a compatible hardwire or parking-power accessory rather than normal switched socket power.
A hardwire kit connects through the vehicle's electrical system and may provide battery-protection functions. Because installation involves the fuse box and vehicle wiring, follow the instructions supplied with the specific accessory or use someone familiar with automotive electrical systems.
First Power-On
After power and storage are ready, check that the camera starts and begins recording normally.
[reference] Title: Recording Status Text: Look for the recording symbol, indicator, or on-screen status provided by your model. Title: Date and Time Text: Set the correct local date, time, and time zone so saved clips have useful timestamps. Title: Video Quality Text: Select an appropriate supported resolution and quality setting for the detail and storage use you prefer. Title: Loop Recording Text: The camera records in segments and reuses storage as normal loop files age. Title: G-Sensor Text: Impact sensitivity affects when supported models protect or classify an event recording. Title: Audio Text: Choose whether in-cabin sound is recorded when the model provides an audio setting. Title: WDR or HDR Text: If your model provides these image options, they can help manage scenes with bright and dark areas. Title: Parking Surveillance Text: Availability and required power accessories depend on the dash cam model. [/reference]If the camera reports that no card is present or shows a storage warning, check that the card is fully inserted and formatted correctly.
Set the Basic Recording Options
- Set the preferred language where that option is available.
- Correct the date and time before the first drive.
- Some models may synchronize time through the app or supported positioning features.
- Choose a supported recording resolution and quality level that suits your storage needs.
- Select the preferred loop segment length. Options such as 1, 2, or 3 minutes may be available on some models.
Shorter loop segments can make a specific moment easier to locate, while longer segments create fewer files. Higher-resolution or higher-quality recording generally uses storage more quickly.
[tip] Medium G-sensor sensitivity can be a practical starting point when that adjustment is available. If normal bumps create too many protected recordings, review the sensitivity setting. [/tip]Connect the 70mai App
For models with app control, the dash cam can create a Wi-Fi connection used for live view, settings, and access to recordings.
[step] 1. Turn on the dash cam's Wi-Fi hotspot using the control available on your model 2. Check the dash cam's network name and password 3. Open Wi-Fi settings on your phone and connect to the dash cam network 4. Enter the displayed or configured password 5. If the phone reports that the network has no internet access, remain connected while using the dash cam 6. Open the 70mai app 7. Add a new device and choose the corresponding dash cam model when prompted 8. Grant the permissions required by your phone and app version for the features you intend to use 9. Follow the in-app connection flow until the camera is available [/step]After connection, supported models can provide live view, easier settings adjustment, and access to clips for viewing or saving to the phone.
Adjust the Camera View
Use the dash cam preview or app live view to aim the lens before the first proper drive.
[step] 1. Aim the camera toward the road ahead and horizon 2. Keep only a small portion of the hood or dashboard near the bottom of the frame 3. Avoid pointing so high that the frame contains excessive sky 4. Avoid pointing so low that the nearby road or hood dominates the view 5. Secure the adjustment mechanism so normal vibration does not move the camera 6. Record a short drive and review the result [/step]A useful starting composition is roughly 10–20% vehicle hood or dashboard at the bottom of the image, with most of the frame covering the road ahead.
Review a Sample Clip
- Check that lane markings and road edges are clear.
- Check whether nearby vehicle plates are reasonably readable under the recording conditions.
- Look for excessive vibration or movement.
- Adjust the angle slightly and test again if necessary.
First Drive Check
Use a short normal trip to confirm that recording continues after installation.
[checklist] * Recording status remains active while driving * Camera stays secure over normal bumps and turns * Loop recordings appear in sequence after the drive * Protected or emergency recordings are created when an event is detected, if supported and triggered * A downloaded sample clip plays normally * Video appears smooth and clear * Audio is present if audio recording was enabled [/checklist]If you are testing G-sensor behavior, remember that higher sensitivity may classify ordinary bumps or sudden vehicle movement as events.
After the test, park safely before opening the file list or reviewing recordings in detail.
Daily Use and Care
[reference] Title: Before Driving Text: Glance at the dash cam after starting the vehicle and confirm that it powers on and shows an active recording status. Title: Weekly Check Text: Look for storage warnings and gently clean dust or fingerprints from the lens with a soft cloth. Title: Storage Care Text: Periodically review recent recordings and format the memory card when appropriate after saving anything important. Title: After an Incident Text: Use the available emergency or lock control when supported, then save the important clip so normal loop recording does not replace it. [/reference] [warning] Always save important footage before formatting the memory card or performing storage maintenance. [/warning]Occasionally review a recent recording rather than relying only on the recording indicator. This confirms that the camera angle, video quality, storage, and optional audio are still working as expected.
