How to Connect Your 70mai Dash Cam to 4G LTE

Quick answer

To connect a 70mai dash cam to 4G LTE, install the compatible LTE module in the camera's accessory port, power the camera, insert and activate a data SIM, then pair the camera with the 70mai app and enable remote monitoring. Confirm your exact model supports LTE before buying a module—the 70mai Dash Cam 4K A810S and 70mai Dash Cam Omni 360° Full View are two models in the current lineup with 4G LTE support.

Check LTE support and module compatibility first

Not every 70mai dash cam accepts an LTE module. The 70mai Dash Cam 4K A810S and the 70mai Dash Cam Omni 360° Full View both list 4G LTE support in their catalog specifications, so they are the safest starting points if remote monitoring is a priority. For any other model, check the product page or the camera's settings menu for a cellular or LTE option before ordering hardware—if the menu entry does not exist, the camera cannot use a module.

Compatibility is model-specific, and a module sold for one 70mai camera may not fit another. Match the module part number to your exact camera model rather than assuming a universal fit. If you are still choosing a camera, treat built-in LTE support as a feature worth confirming at purchase, because it cannot be added later by firmware.

Install the LTE module and prepare the SIM

Power the camera off, then seat the LTE module firmly in its accessory port until it clicks or seats flush. A partially inserted module is the most common cause of a camera that powers on but never finds a network. Next, insert a data-enabled SIM into the module's tray. Use a SIM that has an active data plan; a voice-only or expired SIM will register on the network but fail to pass data, which looks identical to a broken module in the app.

After inserting the SIM, power the camera back on and give it 30–60 seconds to initialize the modem. Watch for a signal or LTE indicator on the camera screen or in the app. If no indicator appears, reseat the module and SIM before troubleshooting anything else.

Pair the camera with the 70mai app and enable remote monitoring

Open the 70mai app, add the camera, and complete the Wi-Fi pairing step as you normally would for a local connection. Once the camera is paired, open its settings and turn on the cellular or 4G LTE option. This is the step people skip: the camera can be paired successfully over Wi-Fi while cellular remains switched off, so remote monitoring will never work until you enable it explicitly.

After enabling LTE, the app should show the camera as online when you are away from its Wi-Fi network. Test this by turning off your phone's Wi-Fi and opening the camera in the app over mobile data. If it loads, remote monitoring is active. If it does not, the issue is almost always the SIM plan, the module seating, or the LTE toggle—not the camera itself.

Keep the connection stable and manage data use

Remote monitoring depends on a consistent cellular signal, so mount the camera where the windshield does not block reception with a metallic or heavily tinted area. Buffered emergency recording and parking surveillance features can generate more uploads, so choose a data plan sized to how often you actually check the camera remotely. If you only review clips occasionally, a modest monthly data allowance is usually enough.

If the camera drops offline repeatedly, check the SIM balance first, then reseat the module, then confirm the LTE toggle is still on after any firmware update. Updates occasionally reset network preferences, and re-enabling LTE takes seconds.

Step-by-step 4G LTE connection

1. Confirm your camera supports LTE: Check the product page or the camera's settings for a cellular or LTE option. The 70mai Dash Cam 4K A810S and 70mai Dash Cam Omni 360° Full View both support 4G LTE. Checkpoint: if there is no LTE menu entry, stop—no module will make it work.
2. Install the compatible LTE module: Power the camera off, then seat the module fully into its accessory port until it is flush. Use the module matched to your exact camera model. Common mistake: a partially seated module powers on but never finds a network.
3. Insert an active data SIM: Place a data-enabled SIM in the module's tray and power the camera on. Allow 30–60 seconds for the modem to initialize. Checkpoint: a signal or LTE indicator should appear on screen or in the app.
4. Pair the camera in the 70mai app: Add the camera and complete the standard Wi-Fi pairing process before touching any cellular settings. Common mistake: skipping pairing and expecting remote access to work immediately.
5. Turn on the cellular or 4G LTE toggle: In the camera's app settings, enable the LTE option explicitly. Pairing over Wi-Fi does not switch cellular on by itself. Checkpoint: the camera should appear online when your phone is on mobile data.
6. Test remote monitoring away from Wi-Fi: Turn off your phone's Wi-Fi and open the camera in the app. If it loads over mobile data, remote monitoring is working. If it fails, check the SIM plan, reseat the module, and confirm the LTE toggle is still on.

Products that support this setup

• 70mai Dash Cam 4K A810S with Sony STARVIS 2 IMX678, License Plate Enhancement, Buffered Emergency Record, Supercapacitor & 4G LTE: The 70mai Dash Cam 4K A810S supports 4G LTE and includes buffered emergency recording, Sony STARVIS 2 IMX678, and 70mai Night Owl Vision for low-light clarity. If you want remote monitoring plus strong night footage, this is a model where LTE is part of the design rather than an afterthought.
• 70mai Dash Cam Omni 360° Full View with Built-In eMMC, AI Detection & 4G LTE Supported: The 70mai Dash Cam Omni 360° Full View supports 4G LTE and uses a 340° rotating motor with 140° lens field of view for full-surround coverage. Remote monitoring is more useful when the camera can be aimed remotely, which this rotating design allows.
• 70mai CPL Filter for Dash Cam A410/ A510/ A800SE/ A500S/ Lite 2: The 70mai CPL Filter is compatible with the A510, A800S, A500S, and Lite 2, and reduces windshield reflections and intense sun while improving color saturation. If you add a CPL filter for clearer footage, check compatibility with your specific camera model—it is not listed for every 70mai dash cam.
