Use your Android phone to review, save, organize, share, and clear 70Mai Dash Cam recordings. The exact folders, recording categories, clip lengths, and available controls can vary by dash cam model and 70Mai app version.
[reference] Title: Loop recordings Text: Regular driving footage is recorded as short segments so older normal footage can be replaced as storage fills. Title: Emergency recordings Text: Important event footage may be stored separately and protected from normal loop overwriting. Title: Parking recordings Text: Supported models may create parking footage from collision detection or other parking recording modes. Availability and accessory requirements vary by model. Title: Downloaded copies Text: A clip downloaded to the phone is a separate copy from the recording stored on the dash cam. [/reference]How Recording Files Are Organized
70Mai dash cams normally record a drive as multiple video segments rather than one continuous file. Depending on the model and recording settings, loop duration may be adjustable, commonly around 1, 2, or 3 minutes.
Short segments make it easier to find a specific moment, preserve only the needed footage, and manage loop recording efficiently.
Common Recording Categories
- Normal: routine driving footage handled by loop recording. Older normal clips can be replaced as the memory card fills.
- Emergency or Event: recordings created after a detected impact or a manual event action on supported models. These are normally stored separately from regular loop footage.
- Parking: footage created by supported parking-surveillance functions. The available parking modes and required accessories vary by model.
Access Videos with the 70Mai App
On models with app control and built-in Wi-Fi, the 70Mai app can be used to browse recordings stored on the dash cam and save selected footage to the phone.
Connect the Dash Cam
[step] 1. Power on the dash cam 2. Enable its Wi-Fi hotspot if it is not already active 3. On Android, connect to the Wi-Fi network created by the dash cam 4. Enter the dash cam Wi-Fi password if requested 5. Open the 70Mai app and select the connected dash cam [/step] [note] The location of the Wi-Fi control and the connection flow can vary by 70Mai model and app version. [/note]Browse Recordings
Open the recording or album area in the app. Depending on the model, you may see groups such as normal, emergency/event, or parking footage.
Recording entries can include information such as:
- Preview thumbnail
- Date and time
- Clip duration
- Recording or event category
You can select a recording to review it through the dash cam connection. Supported app versions also provide a control for downloading saved footage to the phone.
Save Clips to Android
Download important footage before relying on it for later use. A downloaded copy remains on the phone independently of the dash cam's normal loop-recording cycle.
Save One Clip
[step] 1. Connect Android to the dash cam and open the 70Mai app 2. Open the recording category containing the clip 3. Select the video you want to keep 4. Use the available download or save control 5. Check that the saved copy is available on the phone before deleting anything from the dash cam [/step]Save Several Clips
Some app versions provide multi-select or batch actions. If available, select the clips around the event you want to preserve and download them together.
Keeping several consecutive segments can be useful when the relevant moment crosses the boundary between two recordings or when footage immediately before and after an event is important.
[tip] Stay close to the vehicle while transferring footage. For a large group of recordings, smaller batches can be easier to manage over the dash cam's short-range Wi-Fi connection. [/tip] [dosdonts] Do: Keep the phone connected to the dash cam until the transfer completes Do: Confirm important clips were saved before clearing camera storage Dont: Move far away from the dash cam during a large transfer Dont: Lock the phone or switch away from the transfer unnecessarily if doing so interrupts your app version [/dosdonts]Find Downloaded Videos on Android
Downloaded clips are stored on the Android device rather than only on the dash cam memory card. Their visible location depends on the 70Mai app version and Android storage behavior.
You may find saved footage in:
- The 70Mai app's local album or downloaded-file area
- A 70mai or app-related folder visible in a file manager
- The phone's Videos or Movies collection
- The gallery or another media app after Android indexes the file
If you use a file manager, check the phone's video locations and app-created media folders. Avoid assuming that every Android version uses the same directory.
Recordings are commonly stored as video files such as MP4, while the video codec can vary by dash cam model and recording mode.
Play and Review Clips
The 70Mai app is convenient for reviewing footage associated with the dash cam. Downloaded files can also be opened from Android's gallery or file manager.
When reviewing a clip in the app, available controls may include timeline navigation and indicators associated with event or emergency recordings.
If a downloaded video does not display correctly in the phone's default player, the recording may use a video codec that the player does not fully support. A video player with broader codec support may handle the file more reliably.
Organize Saved Footage
Timestamp-based filenames are useful for recording order but can become difficult to recognize later. After downloading important clips, you can organize the phone copies without changing the recordings that remain on the dash cam.
Rename Important Files
[step] 1. Open the Android file manager 2. Locate the downloaded dash cam recording 3. Select the file and choose Rename 4. Use a clear name that includes the date and purpose [/step]Examples of simple names include:
2025-03-20_accident_front.mp42025-03-20_highway_trip_part1.mp4parking_hit_2025-03-21_night.mp4
Avoid unusual special characters if the file may later be moved between different apps or storage devices.
Create Purpose-Based Folders
For a larger collection, folders can separate important footage from routine recordings. For example:
DashCam/AccidentsDashCam/ParkingEventsDashCam/RoadTrips
You can also organize clips by date. A predictable folder structure makes recordings easier to find when they need to be shared later.
Share a Video
Once a recording is stored on Android, it can be shared from the 70Mai app, gallery, or file manager using the phone's normal share controls.
[step] 1. Select the saved clip 2. Tap the available Share action 3. Choose the app or service you want to use 4. Check the resulting file before sending it [/step]High-resolution clips can be large, and some messaging services may impose file-size limits or compress the video.
[warning] For footage that may be needed as evidence, keep an unchanged copy of the original downloaded recording. If you create an edited version for sharing, preserve the original separately. [/warning]Trim a Copy
If only a short part of a recording is relevant, Android gallery or video-editing tools can be used to trim a copy. Keeping the original file unchanged gives you both the complete recording and a smaller version that is easier to send.
Manage Android Storage
Downloaded dash cam recordings can consume significant phone storage, especially when many high-resolution clips are retained.
Check Storage Use
Use Android's storage settings to review the space occupied by videos, apps, and other files. Dash cam downloads may appear as video storage or as storage associated with the app.
Remove Unneeded Copies
After confirming that important recordings are preserved, consider removing phone copies that no longer have a purpose, such as:
- Test recordings
- Routine drives with no event to preserve
- Older parking footage that is no longer needed
Depending on where a downloaded copy is stored, it may be removable from the 70Mai app, Android gallery, or file manager.
Move Older Clips Elsewhere
For longer-term storage, downloaded footage can be moved from the phone to another storage location, such as:
- A USB drive or card reader connected through USB OTG
- A computer
- Network or other storage available to the phone
Verify that the copied files open correctly before removing the phone copies.
Access the microSD Card Directly
A compatible Android phone and USB OTG card reader can provide direct access to the dash cam's removable microSD card. This can be more convenient for a large batch of recordings than transferring each clip over Wi-Fi.
[warning] Power the dash cam off before removing its microSD card. Do not remove or disconnect storage while files are being written or copied. [/warning] [step] 1. Power off the dash cam 2. Remove the microSD card 3. Insert it into a compatible microSD card reader 4. Connect the reader to the Android device through USB OTG 5. Open the Android file manager and browse the card 6. Copy the recordings you want to keep 7. Safely eject the storage before unplugging the reader 8. Return the card to the dash cam only after Android has finished all file operations [/step]The card may contain separate directories for different recording types, including normal, emergency/event, or parking footage. Exact folder names vary by model.
With direct card access, Android may allow normal file operations such as copying, moving, renaming, or deleting. For recordings that still need to be used by the dash cam, copying to the phone first is the safer organization method.
Camera Files and Phone Copies
[compare] Dash cam copy | Stored on the dash cam's memory card and managed by its recording and loop-storage behavior Android copy | Created after a download or manual copy and remains on the phone until it is separately moved or deleted [/compare]Deleting a recording from the dash cam does not normally delete a separate copy that was already downloaded to Android. Likewise, deleting the Android copy does not by itself clear the original recording from the dash cam.
Safe File-Cleanup Order
[checklist] * Download or copy the important recording * Confirm the saved file opens correctly * Organize or back up the copy if it needs to be retained * Only then remove redundant footage from the phone or dash cam [/checklist]Basic Playback and Transfer Checks
[troubleshoot] Problem: A downloaded video has audio but the picture does not display correctly Cause: The phone's default player may not support the recording codec Fix: Try the clip in a video player with broader codec support Problem: A downloaded video appears incomplete Cause: The transfer may have been interrupted, or the source recording may not have been written correctly Fix: If the original is still available on the dash cam, download or copy it again before deleting the source Problem: A Wi-Fi download stops before completion Cause: The dash cam connection may have weakened, the transfer may be too large, or the phone may have limited free storage Fix: Stay close to the dash cam, confirm available phone storage, and retry with fewer clips if needed Problem: Downloaded footage is visible in the app but not in the Android gallery Cause: The file may be stored in an app-specific location or Android may not yet have indexed it for the gallery Fix: Check the app's local album and Android file manager; gallery visibility can vary by Android and app version Problem: Repeated recordings cannot be read reliably from the memory card Cause: The card or its stored data may require attention Fix: Preserve any readable important footage first, then use only the card-maintenance options appropriate for the dash cam model [/troubleshoot]Practical File Routine
After an Important Event
- Use the dash cam's available event or lock function when appropriate.
- Save the relevant recording segments to Android as soon as practical.
- Include nearby segments when they provide useful context before or after the event.
- Keep an unchanged copy in a separate safe location if the footage is important.
After a Long Drive
- Browse the recordings in the 70Mai app.
- Save any clips you want to keep.
- Remove unneeded copies only after confirming important footage has been preserved.
Periodically
- Check how much Android storage is being used by dash cam footage.
- Move older recordings to longer-term storage when appropriate.
- Delete files that no longer need to be retained.
- Keep important recordings in clearly named folders.
