Installing a car DVR is not just a formality, but a critical step that determines the quality of the recording and ultimately your safety on the road. 70mai They face a problem when the purchased gadget after a few weeks simply falls off the windshield, leaving the owner without video evidence in a controversial situation. 3M-scotch.
In this article, we will discuss in detail how to securely secure the DVR so that it will serve you faithfully for many years. We will look at the nuances of the choice of location, the features of working with the adhesive base at different temperatures and how to covertly connect the power to preserve the aesthetics of the interior of the car. Proper installation is the guarantee that the camera will always look where it needs to be and will not stop writing at the most inappropriate moment.
Choosing the optimal location for installation
The first and most important step is to determine the mounting point. The standard seat for most 70mai A500S or M300 models is behind the rear-view mirror, where the device does not overlap the driver's view and is as protected from direct sunlight as possible, which reduces the risk of battery and matrix overheating. However, if you plan to use parking mode, you may need to shift the mount closer to the center of the windshield.
It's important to consider the design of your car. In some car models, the area behind the mirror can be shaded with silkscreen (black dots on the glass), which makes it difficult to stick. If you stick the holder strictly on the dots, the clutch will be weak. You need to find a balance so that the lens looks clearly in the center of the road, and the base of the holder gets on the smooth surface of the glass or as tightly as possible to the silkography relief.
- 🚗 Make sure that the selected place does not block the driver’s view and does not interfere with the work of janitors.
- 📡 Check if the installation area falls into the confident reception area GPS/GLONASS, if your model does not have a remote antenna.
- ☀️ Avoid places where the sun shines constantly in the summer to prevent electronics from overheating.
⚠️ Warning: Never place the recorder on the moving parts of a torpedo or on plastic that vibrates strongly on the move.Vibration will cause a "jelly effect" on video, making car license plates unreadable.
Also worth paying attention to is the angle of view. Most modern Xiaomi models have a wide angle, but if the edges of the frame are too low or high, the optimal height is when the horizon line is about the grey of the frame or just below, this ensures better readability of the numbers in front of the cars and capture the side of the road.
Preparation of surface and glue base
Clutch quality 3M-So even a microscopic layer of grease from your fingers or from the dirt can cause the mount to fall off in a month, and you have to carefully degrease the area before you start mounting. For this, it is best to use isopropyl alcohol or special wipes for cleaning glasses, which often come with a kit.
Many users make the mistake of relying on a factory sticker. To enhance the effect, it is recommended to use a special primer (adhesion activator), which is applied with a thin layer on the glass before gluing. If there is no primer, you can use ordinary alcohol, but it is important to let it completely evaporate before contact with the glue. The ambient temperature also plays a role: the ideal conditions are +20 ° C and above.
The process of removing the protective film from 3M-Scotch requires care. Don't touch the adhesive layer with your fingers, because the skin fat reduces adhesion. If you install the device in a cold cabin in winter, the adhesive base will be hard and will not be able to fill the micro-units of the glass. In this case, it is recommended to warm up the mounting platform and the glass itself with warm air from a hair dryer or simply hold the cabin warmed up for about 15 minutes.
- 🧼 Carefully wipe the glass with an alcohol napkin in circular movements.
- 🌡️ Warm up the glass and glue base to room temperature before installation.
- 🚫 Do not touch the sticky layer with your fingers. 3M-scotch after removal of defense.
Proper adhesion technology
The most critical thing is the physical connection of the holder to the glass, after you've degreased the surface and removed the protective film from the glass. 3M-Scotch tape, you need to apply the mount to the glass immediately. Don't try it on weight after you take the film, because you can't glue it back to the top again.
Press the holder firmly and evenly over the entire area. Pay special attention to the edges. Pressure must be strong to squeeze possible air bubbles from under the glue. Hold the mount tight for 30-60 seconds. There is a common misconception that you can hang the heavy body of the device immediately after you stick. This is a mistake.
☑️ Checklist of correct installation
⚠️ Warning: After installing the holder, it is strongly recommended not to hang the DVR itself for 24 hours.
If you use a rotary or suction model (although it's less typical for a 70mai, it's more often static), make sure the latching mechanism works smoothly. In some cases, if the holder's plastic is too smooth, you can gently apply an extra layer of plastic glue, but only if you're confident in your skills, as it's going to be extremely difficult to peel off afterwards.
Comparison of anchorage types
The Xiaomi 70mai range uses different approaches to fixing a device. Understanding the differences will help you use the gadget correctly. Some models involve rigid fixation, others - rotary. Below is a table comparing the main characteristics.
| Type of attachment | Reliability | Comfort of removal | Risk of falling |
|---|---|---|---|
| 3M Scotch (Static) | Tall. | Low (to be cut off) | Minimum |
| 3M + Turning hinge | Medium | Average. | Medium (wear of hinge) |
| Suction (rarely) | Low (depending on temperature) | High. | High in the heat. |
| Adhesive tape (bilateral) | Very high. | Low. | Minimum |
Static 3M tape attachment is considered the gold standard for Chinese recorders, providing a rigid bond to glass, which is critical to the operation of the G sensor. If the device is hanging on the suction cup, the impact sensor may falsely fire from vibration or, conversely, not detect the real impact due to the backlash.
At the same time, the swivel mechanisms are convenient if you plan to periodically rearrange the camera, for example, when driving a car or washing, but over time, the plastic at the connection point may weaken, and the camera will start to peck nose down under its own weight, so for constant use, it is better to choose options with a rigid fixation.
What to do if the scotch stopped holding?
Food and wire concealment
Once the device is fixed, it raises questions of aesthetics and safety. A hanging power wire is not only ugly, it's also dangerous, because it can catch on to the controls or limit visibility. Xiaomi cars typically use a micro-USB or USB Type-C cable that needs to be run from the mirror to the fuse block or lighter.
The best route is along the top edge of the windshield, then into the body rack (torpedo) and down to the blemish. Use a plastic blade to fill the wire into the skin, trying not to damage the seals. If you connect to the lighter, you can run the wire over the center console, hiding it under decorative linings.
- 🔌 Use a plastic blade for a careful filling of the wire under the skin.
- 🛡️ Do not clamping the wire with sharp edges of plastic so as not to damage the insulation.
- 🔋 For parking mode, consider installing a separate hardwire cable.
Special attention should be paid to connecting through the Hardwire Kit, which allows you to implement the function of round-the-clock parking, when the 70mai turns on while driving and goes into tracking mode when parking, and with this connection it is important to choose the right fuse that does not turn off when you turn off the ignition if you want monitoring, or shut down if you only need to record in motion.
💡
Use screeds or isolets in cabin color to fix the excess length of the cable in the hidden cavities, preventing wires from rattling on uneven roads.
Initial adjustment and installation verification
When the physical installation is complete, you need to check the system. Turn on the device and wait for the download. Using the 70mai app on your smartphone (connected via Wi-Fi), evaluate the picture. Make sure the horizon is flat, and the torpedo edge or the holder does not get into the frame. If the image is inverted or shifted, you may need to physically adjust the angle of inclination.
Also check the microphone and Wi-Fi module. If you hid the device deep behind the mirror, the Wi-Fi signal can be worse, but usually it's enough for quick setup. Make sure the memory card is formatted in the FAT32 or exFAT file system and is determined by the device. The recording error often arises precisely because of poor card contact or poor quality.
⚠️ Warning: Before you start moving, make sure to check that the recording indicator is on the screen.
The important step is to set up the G sensor, so if it's too sensitive, each brake will be perceived as an accident, and the old file will be protected from overwriting. If it's too weak, the impact may not be recorded. The optimal average is set and a test ride is taken, abruptly braked at the safe site to check the reaction.
Frequent errors in installation
Even experienced motorists sometimes make simple mistakes that negate all efforts. One of the most common is to install in the cold without warming up. The glue simply does not catch, and after a couple of days in the sun the device falls; the second mistake is the use of poor-quality memory cards, which leads to constant overwriting and eventual failure of the drive.
Another problem is ignoring the direction of travel, and the camera has to look straight ahead, and if you've set it up with a bias, the video will skew the perspective, and in the event of an accident, the insurance company may question the accuracy of the recording, claiming that the angle of view is not true.
💡
The key to a reliable 70mai installation is patience, so let the glue freeze for 24 hours before it is used, and the device will hang for years.
Also worth mentioning is the cleanliness of the lens itself. Before your first trip, wipe the lens with a soft cloth. Fat fingerprints left during editing will turn into lights from oncoming headlights at night, making the video useless. Use special spray-anti-rain sprays on the outside of the glass, but it is better not to apply aggressive chemistry to the lens of the recorder.
