Wi-Fi is how your 70Mai Dash Cam talks to your Android phone. The dash cam creates its own hotspot, your phone connects directly to it, and the 70Mai app uses that link to show live view, sync settings, and download videos. Getting this Wi-Fi and hotspot setup right makes everything else—firmware updates, file management, GPS playback—much smoother.
1. How Wi-Fi Works on the 70Mai Dash Cam
Your 70Mai Dash Cam does not connect to your home router like a normal device. Instead:
-
The dash cam acts as a Wi-Fi hotspot (access point).
-
Your Android phone connects directly to that hotspot.
-
The 70Mai app communicates with the camera over this direct link.
Key points:
-
The dash cam hotspot usually does not provide internet access.
-
Android may warn “No internet connection”—this is normal and not an error.
-
Some models also support Bluetooth for quick pairing, but Wi-Fi is still used for live view and file transfers.
Think of it as a private, short-range Wi-Fi tunnel between your phone and the dash cam.
2. Enabling Wi-Fi Hotspot on the 70Mai Dash Cam

The exact steps vary between models (with or without screens), but the logic is the same: power the camera, then enable its hotspot.
2.1 General Steps on the Dash Cam
-
Power on the dash cam
-
Start the car or turn the ignition to accessory mode.
-
Wait until the dash cam finishes booting.
-
-
Open the Wi-Fi menu
-
On models with a screen:
-
Press the Menu/Settings button.
-
Navigate to Wi-Fi, Hotspot, or App Connection.
-
-
On button-only models:
-
Long-press a dedicated Wi-Fi or app button (often marked with a Wi-Fi symbol).
-
Or follow the quick key combination described in the manual.
-
-
-
Enable Wi-Fi
-
Toggle Wi-Fi: ON or Hotspot: ON.
-
The dash cam should display:
-
A Wi-Fi icon.
-
A network name (SSID)—usually something like
70mai_xxx. -
A default password.
-
-
Once enabled, the camera is broadcasting its own Wi-Fi hotspot and waiting for your Android device to connect.
3. Connecting an Android Phone to the 70Mai Hotspot
With the hotspot active, link your Android device.
3.1 Step-by-Step Connection
-
On your Android phone, open Settings → Wi-Fi.
-
Wait for the network list to refresh.
-
Look for a network with a name like:
-
70mai_XXXX -
Or similar, printed on the dash cam screen or label.
-
-
Tap the network name.
-
Enter the Wi-Fi password shown on the dash cam (case-sensitive).
-
Confirm and connect.
Android may display:
-
“Connected, no internet” or “No internet access.”
-
This is expected—stay connected anyway.
3.2 Preventing Android From Auto-Switching Away
Because the dash cam hotspot has no internet, Android may try to drop it in favor of mobile data or another Wi-Fi network.
To prevent this:
-
When you first connect, if Android asks something like:
-
“This network has no internet. Stay connected?”
-
Choose Yes, Stay connected, or equivalent.
-
-
Disable features like:
-
“Switch to mobile data when Wi-Fi has no internet”
-
“Smart network switch”
-
“Auto network selection”
-
These options are usually found in Wi-Fi / Network preferences.
Once locked to the 70Mai hotspot, your Android phone is ready for the app.
4. Pairing the 70Mai App With the Dash Cam via Wi-Fi

After the Wi-Fi connection is established, the 70Mai Android app takes over.
4.1 Initial Pairing
-
With your phone connected to the 70Mai Wi-Fi, open the 70Mai app.
-
On first use:
-
Grant necessary permissions, especially Location (Android requires this for Wi-Fi scanning) and Storage.
-
-
In the app:
-
Add a new device if you haven’t already.
-
Choose your dash cam model from the list.
-
-
The app should detect the dash cam over Wi-Fi and link to it.
Once paired:
-
You can see live preview of the camera.
-
Access settings (resolution, loop recording, G-sensor, etc.).
-
Download videos and update firmware.
4.2 Reconnecting on Future Trips
Next time you want to connect:
-
Turn on the car and wait for the dash cam to boot.
-
Enable Wi-Fi on the dash cam (if it doesn’t auto-enable).
-
On Android, reconnect to the 70Mai network if needed.
-
Open the 70Mai app—it should automatically find the camera.
If the app says “Device not found,” first check that your phone is still connected to the dash cam Wi-Fi, not another network.
5. Changing the Wi-Fi Name (SSID) and Password
For better security and easier recognition, you can customize the hotspot name and password.
5.1 Why Change Them?
-
Prevent unauthorized access, especially in crowded areas or taxi/ride-share scenarios.
-
Make it easier to identify the correct dash cam when you have multiple devices (e.g., front and rear).
5.2 Changing Settings Through the App
-
Connect your Android phone to the 70Mai Wi-Fi.
-
Open the 70Mai app and connect to the dash cam.
-
Go to Device Settings → Wi-Fi Settings, Hotspot Settings, or similar.
-
Edit:
-
SSID (network name)—for example:
-
70mai_front_car -
70mai_rear_trunk
-
-
Password—use 8–16 characters with a mix of letters and numbers.
-
-
Save/apply the settings.
The dash cam will:
-
Restart the hotspot with the new name and password.
-
Disconnect your phone from the old network.
Then:
-
Return to Android Wi-Fi settings.
-
Forget the old 70Mai network if needed.
-
Connect to the new SSID using the new password.
5.3 Resetting to Default Wi-Fi
If you forget the password or misconfigure Wi-Fi:
-
On the dash cam, go to:
-
Settings → System / General → Reset Wi-Fi or similar.
-
-
This restores the default SSID and password, usually printed in the manual or shown on screen.
In extreme cases, a full factory reset will also reset the Wi-Fi configuration (but may also reset other settings).
6. Using the Hotspot for Live View, Downloads, and Updates
Once Wi-Fi and hotspot are configured properly, the connection unlocks several important features.
6.1 Live Preview
From the 70Mai app:
-
Tap Live View to see what the dash cam sees in real time.
-
Use this to:
-
Fine-tune camera angle and framing.
-
Verify that the lens isn’t blocked or misaligned.
-
Live view may have a slight delay over Wi-Fi, especially with high resolution—but this does not affect the recording saved to the SD card.
6.2 Downloading Video Files
The dash cam hotspot is the pipeline for video transfers:
-
Browse normal, event, and parking folders from the app.
-
Select clips you want to download to Android:
-
Accident footage.
-
Road trip highlights.
-
Parking incidents.
-
Downloads happen over the camera’s Wi-Fi. To make them smoother:
-
Stay inside the car or close to the windshield.
-
Avoid switching apps or letting the phone sleep mid-transfer, especially for large files.
-
Transfer important clips as soon as you can, so they’re safe from loop overwriting.
6.3 Firmware Updates
Firmware updates usually follow this path:
-
The 70Mai app uses mobile data or another Wi-Fi (home/office) to download the firmware file.
-
Then, while connected to the dash cam hotspot, the app sends the firmware to the camera over its Wi-Fi.
-
The dash cam installs the firmware and restarts.
Because of this, Wi-Fi and hotspot configuration must be stable for firmware upgrades to succeed.
7. Hotspot Security and Best Practices
Even though the dash cam hotspot is short-range, it’s still a wireless access point near public spaces.
7.1 Use a Strong Password
-
Avoid passwords like
12345678orpassword. -
Use at least 8 characters with mixed letters and numbers.
-
Do not share the password freely, especially if your dash cam stores sensitive footage.
7.2 Limit Access to Trusted Devices
-
Only pair your own Android phone (and other phones you trust).
-
If multiple people need access, keep track of who has the password.
-
Change the password if you suspect someone unwanted has it.
7.3 Hide SSID (If Supported)
Some models may allow you to hide SSID broadcast:
-
This won’t make it impossible to find, but it reduces visibility to casual scanning.
-
You will have to manually enter the network name on Android if hidden.
If hiding the SSID causes connection confusion, it’s fine to keep it visible and rely on a strong password instead.
8. Troubleshooting Wi-Fi and Hotspot Configuration
Even with proper setup, Wi-Fi can sometimes misbehave. Most issues come down to a few common causes.
8.1 Phone Connects But App Says “Device Not Found”
Check:
-
Is the phone truly connected to the 70Mai network, not your home or car Wi-Fi?
-
Are Location and Storage permissions granted to the 70Mai app?
-
Is the dash cam fully booted and not restarting?
Try:
-
Closing and reopening the 70Mai app.
-
Forgetting and reconnecting to the 70Mai Wi-Fi in Android settings.
-
Restarting both the dash cam and the phone.
8.2 70Mai Network Not Visible in Wi-Fi List
Check:
-
Is the dash cam Wi-Fi hotspot enabled in its settings?
-
Is the camera fully powered (not in a weird half-boot state)?
-
Are you within range (sitting in the car)?
Try:
-
Turning Wi-Fi off and on on Android.
-
Toggling Wi-Fi off and back on on the dash cam.
-
Moving the phone closer to the dash cam, avoiding thick pillars or metal that might block the signal.
8.3 Connection Keeps Dropping
Possible causes:
-
Android automatically switching to another Wi-Fi or mobile data.
-
Weak signal if the phone is outside the car or too far.
-
Power instability making the dash cam briefly restart.
Fixes:
-
Turn off auto network switching and stay connected to the dash cam network.
-
Sit in the driver’s seat or near the camera during file transfers.
-
Check the dash cam power cable and adapter for loose connections.
8.4 Wrong Password or Forgotten Password
If you changed the password and forgot it:
-
Reset Wi-Fi settings on the dash cam to default from the menu.
-
Then reconnect from Android using the default password shown on the camera or manual.
If you repeatedly get “incorrect password” on Android:
-
Tap Forget on the 70Mai network in Wi-Fi settings.
-
Re-enter the password carefully, respecting case and characters.
9. Practical Hotspot Usage Tips
To make Wi-Fi and hotspot use feel natural instead of annoying:
-
Use it when parked and safe
-
Configure settings, download files, and check clips while the car is stationary.
-
Avoid trying to manage the app while driving.
-
-
Create a simple routine
-
Start car → enable Wi-Fi on dash cam (if not auto) → connect Android → open 70Mai app.
-
-
Keep the hotspot name logical
-
For multiple cameras, set SSIDs like:
-
70mai_front -
70mai_rear
-
-
-
Turn off hotspot when done (optional)
-
To reduce interference and a small amount of power use, you can disable Wi-Fi on the dash cam after finishing transfers.
-
With a properly configured hotspot and a stable Wi-Fi link, your 70Mai Dash Cam and Android phone work together as one system—live preview, settings, downloads, and updates all flow through that connection, turning a small camera on the windshield into a fully manageable, smart driving companion.
