Guidance in Questions and Answers for the 70mai M310 Dash Cam
Does the 70mai M310 support in-cabin recording?
No. The dash cam has no built-in interior camera and does not support an external one. The device records only the road scene in front of the vehicle.
What are the recording resolution and frame rate of the M310? Is H.265 supported?
The dash cam records in 2K QHD 2304x1296 at 30 fps. The firmware uses the H.265 (HEVC) codec to save storage space without noticeable loss of quality. This information applies to the 70mai M310 dash cam.
Does the M310 record audio?
Yes. The device has a built-in microphone; audio recording can be enabled or disabled in the 70mai application.
Is voice control available and in which language are the commands?
Voice control is supported in English (for example, saving an important clip). Russian voice commands are not supported.
What power specifications and connector does the 70mai M310 use?
Power 5 V, 2–2.4 A via a USB Type-C connector. The package includes a car charger for a 12–24 V system and a USB-A to Type-C cable. This information applies to the 70mai M310 dash cam.
Can the dash cam be powered from a head unit’s USB port or the overhead console?
Yes, if the port reliably provides 5 V and 2–2.4 A. Insufficient or unstable power may cause spontaneous restarts and recording errors.
.Is it safe to use fast chargers (QC/PD)?
Undesirable. Ports that automatically raise voltage to 9–12 V using QC/PD may damage the dash cam’s electronics. Use the 5 V mode (2–2.4 A).
Will the M310 operate from its internal battery without external power?
No. The built-in battery (~300 mA·h) serves to properly finalize recordings and preserve the date/time and settings, but not for standalone operation.
Supported memory cards and maximum capacity
microSDXC UHS-I U3 V30 cards with capacities of 16–256 GB are recommended. Lower-class cards (U1) may cause dropped frames and errors.
How much video fits on a memory card?
Approximate continuous recording duration in 2K: 16 GB — ~2.7 h; 32 GB — ~5.5 h; 64 GB — ~11 h; 128 GB — ~22 h; 256 GB — ~44 h. This information applies to the 70mai M310 dash cam.
Is loop recording available? Is manual card cleaning required?
Yes, recording is looped: when the storage is full, new files automatically replace the oldest ones (except those marked as important). Manual formatting is usually not required.
What is the duration of a single file and where can it be changed?
Available lengths are 1, 2, or 3 minutes. The parameter is configured in the 70mai application.
Why is the video greenish/turquoise?
Check whether the protective film remains on the lens. Its presence causes color distortion and reduced sharpness.
How does the M310 perform with a tinted windshield?
The image will be darker in proportion to the level of tint. For the best result, place the camera in an area with minimal dimming.
How do I connect to the dash cam from a smartphone? Is the internet required?
The device creates its own Wi-Fi access point; the internet is not required. Connect to the dash cam’s Wi-Fi and work in the 70mai application.
Why does my phone show “Wi-Fi without internet access”?
This is normal: the dash cam’s network serves only for communication with the smartphone. It does not provide internet sharing.
Can I connect via Bluetooth or view recordings remotely over the internet?
No. Connection is via Wi-Fi in proximity to the device (typically 1–3 m); remote access over the internet is not supported.
What is the default access point password and what if I forget it?
The standard password is 12345678. If the password has been changed and forgotten, perform a device reset and set a new one in the application.
Can multiple dash cams be added to a single application?
Yes. Several devices can be added to the 70mai application; however, connections and viewing are performed sequentially, not simultaneously.
.Does the 70mai M310 support GPS, speed logging, and coordinates?
No. The model lacks a GPS module; therefore, speed and coordinates are neither recorded nor overlaid on the video.
Can the M310 output video to a head unit display via USB?
No. The USB port is used for power only. Viewing and exporting clips are performed through the 70mai application over Wi-Fi.
How does Parking Mode work and what is required to activate it?
The UP03 (Type-C) hardwire kit is required. Time-lapse recording (1 frame/s) and recording triggered by the G-sensor are available. A motion sensor is not present in this model. This information applies to the 70mai M310 dash cam.
How do I connect the UP03 and what do the wires mean?
Connect to the vehicle’s electrical system: VCC+ (to a constant “+”), ACC (to the ignition “+”), and GND (ground). After installation, you can configure auto-shutdown while parked.
Will the M310 record with the engine off without the UP03?
No. Without the hardwire kit, the device powers off when external power is lost; Parking Mode is available only with direct connection.
Is there a G-sensor?
Yes. The G-sensor saves collision files to a separate folder and can start recording in Parking Mode when the UP03 is used.
Is there a motion sensor?
No. Motion detection is not available; in Parking Mode the device uses time-lapse and the G-sensor.
Can a rear or secondary camera be connected to the M310?
No. The device design does not provide for connecting additional cameras (rear or interior).
How can I remove and reinstall the dash cam on another windshield?
The mount is on 3M adhesive through an electrostatic film. To reinstall, unscrew the pin, remove the unit, and apply new adhesive/film on the other glass.
Can the device be installed upside down?
Physically yes, but the M310 has no “image flip” function, so the video will be recorded upside down.
What is the length of the included power cable?
About 3 m — sufficient for hidden routing along the perimeter of the windshield and pillar.
In what temperature conditions can the device be used?
Manufacturer test range: from ?10 to +60 °C. In extreme cold/heat, avoid prolonged idling without power.
How do I format the memory card on the M310?
On-device option: quick formatting is performed by short button presses (4 consecutive presses). Formatting is also available in the 70mai application. This information applies to the 70mai M310 dash cam.
Which memory cards are preferable for 128–256 GB?
Proven U3/V30-class models are recommended, for example the High Performance or Professional lines from well-known brands. The key is U3/V30 compliance and the exFAT file system.
.Can I view and save videos to a phone without removing the card?
Yes. Connect to the dash cam via Wi-Fi through the 70mai application, open “Albums,” and download the required clips to the smartphone’s storage.
Why do some clips not play on the phone/PC?
Ensure that a modern player with H.265 support is used (for example, VLC). Also verify the health and class of the memory card (U3/V30).
Are date and time preserved when power is disconnected?
Yes. The built-in battery maintains the clock and correctly finalizes the current file when external power is lost.
How legible are license plates in 2K video?
In daytime, plates are generally readable at a distance of about 10–20 m. While driving and at night, recognition depends on speed, lighting, and windshield cleanliness.
Is a Russian-language interface available for the device and the application?
Yes. A Russian interface is available in the 70mai application; the dash cam’s voice prompts are provided by a Russian-language firmware for the local market (voice commands are in English).
