How to install the Xiaomi 70mai DVR: a complete guide from location selection to settings

Why 70mai is a Safety Critical

The Xiaomi 70mai DVR is not just a gadget for recording traffic accidents, but a full-fledged security tool that can be your main proof in controversial situations. However, even the most advanced model is useless if installed incorrectly: shooting at the wrong angle, poor fixation or improper power connection will negate all the advantages of the device.

In this article, we will look at all the steps of installation, from choosing the optimal place on the windshield to the subtleties of setting the viewing angles and connecting to the application, focusing on the typical errors that 90% of drivers make during the first installation, and give unique recommendations for hidden wires without damaging the skin of the cabin.

Preparation: What will be needed for installation

Before you start installing, make sure you have everything you need. The standard Xiaomi 70mai (Pro, Omni, Dash Cam A500S, etc.) includes a suction cup mount, power cable and lighter adapter, but additional tools may be needed to install it accurately:

  • ๐Ÿ”ง Plastic spatula or card for deconstructing the skin (to hide the wires)
  • ๐Ÿงด Alcohol wipes or glass cleaner (for degreasing the surface)
  • ๐Ÿ“ Roulette or line (for precise camera positioning)
  • ๐Ÿ”Œ Multimeter (if you plan to connect directly to the onboard network)

If youโ€™ve bought a recorder without a hidden installation kit, consider buying a hardwire kit (like the 70mai Hardwire Kit), which allows you to connect the device directly to a parking battery, but requires knowledge of auto electrics.

Selection of the installation location: where to fix the registrar

The optimal position of the DVR is a balance between the quality of the shooting and safety. According to the traffic rules of the Russian Federation (paragraph 7.3 of the list of malfunctions), the device should not limit the driver's view and create blind spots.

  • ๐Ÿ“ Behind the rearview mirror (the most popular option, does not interfere with the review)
  • ๐Ÿ“ In the upper corner of the driver's side windshield (optimum for models with a wide viewing angle)
  • ๐Ÿšซ Avoid mounting the center of the glass โ€“ this can distract and close the view

For models with ADAS (collision warning system), it is important that the camera is installed strictly horizontally. Use the level (there is built into many smartphones) or navigate the marking lines on the road.

What happens if you install a crooked recorder?
The wrong angle of tilt will distort the perspective of the video, for example, in a traffic accident, you may not see the license plate of the culprit or the pedestrian on the crossing, and the ADAS system will falsely fire when cornering or driving on rough roads.

Step-by-step instructions for fixing the registrar

Now, let's get to the installation process itself. Follow this algorithm to avoid the typical errors:

  1. Clean the surface of the glass. Rub the selected area with an alcohol napkin to remove the fat and dust, which will ensure a reliable grip of the suction cup.
  2. Hold the holder. Press the suction cup against the glass and lock the lever (the 70mai Pro models have it on the side). Check the reliability by pulling the holder on yourself.
  3. Set the camera up. Set the recorder in the holder and adjust the angle of inclination. For GPS models, it's important that the top of the camera is pointed upwards.
  4. Check the view. Sit in the driver's seat and make sure the camera doesn't close the view or distract.

Power connection: lighter vs direct wiring

The way you connect the power depends on your needs. Most drivers choose a standard lighter adapter, but there are downsides to this method:

  • โšก Hanging wire may interfere with passengers or the driver.
  • โšก The lighter is often busy with other devices (navigator, phone charging).
  • โšก No Parking Recording Feature.

The alternative is to connect directly to the onboard network via a hardwire kit, which is more complex, but has the following advantages:

  • ๐Ÿ”‹ Automatic ignition switching on/off.
  • ๐Ÿ“น Recording in parking mode (when connected to the battery).
  • ๐Ÿš— Clean cabin without hanging wires.

To connect via a hardwire-kit, you will need:

  1. Remove the skin near the fuse block (usually to the left of the steering wheel).
  2. Connect the plus wire to a fuse that is activated when the ignition is turned on (for example, a lighter).
  3. Connect the sub-conductor to the metal part of the body.
  4. Hide the wires under the skin using a plastic spatula.

If you're not sure about your electrician skills, contact the service. Incorrect connection can lead to battery discharge or short circuit.

Setup of the camera and 70mai app

After the physical installation, you need to configure the recorder itself. Most 70mai models support control via a mobile application (available for Android and iOS).

  1. Download the 70mai app from the official store.
  2. Turn on Wi-Fi on the registrar (Wi-Fi button or in the settings menu).
  3. Connect to the Registrar Network (type name) 70mai_XXXX) phone-on.
  4. Follow the instructions in the pairing app.

In the annex, you can:

  • ๐Ÿ“ธ Set up video resolution (1080p, 1440p or 4K model-wise).
  • ๐Ÿ”„ Enable cycling and select segment lengths (1, 3 or 5 minutes).
  • ๐Ÿšจ Activate ADAS (warning of deflection, collision).
  • ๐Ÿ“ก Set up cloud storage (if supported).

โš ๏ธ Attention: When recording in 4K files take up to 1GB in 5 minutes. Make sure you have a class memory card installed U3 or V30 (So, for example, SanDisk Extreme. U1 They may not be able to handle the data flow.

Hidden wire laying: how to hide cables

Hanging wires spoil the aesthetics of the cabin and can interfere with the control. To carefully hide the power cable, follow this instruction:

  1. Disconnect the battery's negative terminal (for safety).
  2. Put a cable along the windshield rack, use a plastic spatula to gently bend the skin and fill the wire in.
  3. Hold the wire along the ceiling, and you can do that with clips or double-sided tape.
  4. Output the cable to the lighter or fuse unit. Some cars (for example, Toyota Corolla or Hyundai Solar) have special channels for wires.

For models with a hardwire whale, the process is more complicated - you will need to stretch the wire to the fuse block, in which case we recommend using corrugated corrugated to protect the cable from rubbing.

๐Ÿ’ก

If your car does not have regular channels for wires, use decorative linings (for example, from 3M), which mask the cable and prevent it from sagging.

Frequent Mistakes and How to Avoid Them

Even experienced drivers sometimes make mistakes when installing DVRs, and here are the most common ones and ways to prevent them:

Mistake.Effects of consequencesHow to avoid
Installation under direct sunlightCamera overheating, glare on videoUse a sunscreen or tinting.
Mounting on dirty glassThe suction cup falls off while movingBe sure to degrease the surface with alcohol
Use of non-original power cableOverheating, short circuit.Buy certified accessories
Wrong angle of inclinationDistorted perspective, invisible car numbersUse level or setting by markup lines

Another common problem is that the battery is rapidly discharged when connected via a hardwire kit, which happens if you don't configure the recorder to shut down when it's low-charge. The 70mai app has a low-voltage protection feature, set a 12.2V threshold to avoid discharge.

Can I install a 70mai on the back window?
Yes, but it would require a dual-camera model (like a 70mai Omni) or a separate rear camera, and note that the rear window mount is less reliable due to vibrations and heat blowing.
How often should I format a memory card?
It is recommended to format the card every 1-2 months through the registrar menu (Settings โ†’ Format) This prevents file fragmentation and write failures.
Can I use a registrar without a memory card?
Technically, it will, but video won't be saved. Some models (like the 70mai Pro+) support cloud storage, but it's paid and requires an internet connection.
Why does the recorder turn off when the engine starts?
This is because of a voltage drawdown in the onboard network, solution: connect the recorder through a hardwire capacitor kit or use a voltage stabilizer.
How to update your firmware to 70mai?
Updates are released via the 70mai app. Connect the registrar to Wi-Fi, open the app and go to Device โ†’ Software Update. Don't interrupt the process!
