24-hour parking monitor
In parking mode, the 70mai camera goes into sleep mode, but continues to monitor vehicles.
The time interval allows you to use the storage and automatically overload the oldest frames.
Due to the G-sensor, the device starts recording the video itself if any collision occurs, and event frames will be saved separately in the event files, avoiding erasure.

4. >Features, description of the functions of the DVR
4.1. Video recording and everything connected with it
  • DVR "out of the box" writes a video in the resolutionFullHD (1920x1080). The maximum available, it is also the optimal resolution (2592x1944) can be enabled via the menu or application provided the codec is selectedh.265.
  • By choosing a video standard (P / N, which corresponds to PAL / NTSC), you can select a frame rate (25/30 fps). PAL = 25fps, NTSC = 30fps (if you see flickerin recording under artificial light -change this settingand the flicker will disappear).Please note that when choosing the PAL standard (25fps) the frame rate in the videos remains 30, but at the same time every 6th frame is a copy of the 5th, because of this, it visually seems that the image is “twitching”.
  • Video is written in fragments by1 minute (can not be changed)without pauses between recordings. (pause is only0.03 sec)
  • When the memory card is full, old videos are overwritten (except for overwritten fragments).
  • There is a shock sensor that allows you to automatically protect the current fragment from being overwritten (this can also be done by pressing a button).
  • Also, the button can turn on / off sound recording.

Useful information:Frame cropping depending on resolution
4.2. Video recording in the parking lot
The recorder has two ways of tracking the car in the parking lot:parking modeandtimelapse mode(Time-Lapse) - recording accelerated video (1 frame per second).
  • Timelapse modeAvailable only in the Chinese firmware and only when the original lace is connected, which provides constant power to the DVR and does not completely discharge the car's battery.More here.
  • Parking modehas two settings - oneturns on / offhis secondsets the timethrough which the recorder will turn itself off if there is no movement (as indicated by the shock sensor).
    If aparking mode is on, the recorder will turn on automatically when a shock sensor is triggered and record 1 minute of video (the screen does not light up). If in the process of recording there will be another triggering of the shock sensor, the recorder will turn on completely (as if the button was pressed) and will record video continuouslybefore the time specified in the settings(including when power is off, and even in your pocket).

The recorder is turned off for the following events:
? by holding the power button;
? when disconnecting the external power supply;
? at expirationoff delay time- provided thatparking mode is onand the recorder all this time was at rest (according to the shock sensor).
4.3. GPS
GPS comes as an optional module and is not included as standard.
Starting with firmware 1.0.5 and application version 1.2.0, the function of displaying GPS coordinates is active. For details, see paragraph 10 of the caps.
RegistrarNOTsynchronizes time with GPS data.
4.4. ADAS (driver assistance systems)
ADAS = advanceddriver-assistancesystemsor advanced driver assistance systems.
To work ADASGPS module required. From it, the system receives data about the speed of the car. Without this data, no component can work.
Before you start, ADAS must be calibrated. Ideally, calibration should be done on a good road with clear markings.

ADAS in the registrar consists of 3 components:
  • Warning of a dangerous approach(FCWS = Forward Collision Warning System)
    It works only in motion (from 5-10 km / h). In essence, this is a distance control. The system determines the distance and if it is too small for the current speed, it will give a warning.
  • Lane departure warning(LDWS = Lane Departure Warning System)
    Runs at speeds above 80 km / h. At each detection of the intersection of the marking lines reports this.
  • Message about the beginning of the movement in front of the standing car(FVSA = Front Vehicle Start Alarm)
    It works only when the machine is standing still. If the car in front starts moving, reports it.



Review, some details and video examples
4.5. Autonomous work (from the built-in accumulator)
  • The built-in 500mAh battery, when fully charged, allows the recorder to continuously record video for a little over 50 minutes.
  • In the observation mode on the parking of this capacity, there is a little more than 40 inclusions on the impact sensor (40 videos of 1 minute each).
  • Battery is chargingexclusivelywhen the registrar is on.If the recorder is off or in standby in the parking mode, the battery is NOT CHARGED.
4.6. E-Dog / Speedcam / radar base
This function is present only in the Chinese version of the firmware andworks exclusively in China.
So far nothing is known about the format of the camera base and the possibility of using non-native bases.

9. & Device firmware
9.1. General information - required to familiarize
Before flashingis recommendeddisable parking mode! ("parking surveillance", "parking surveillance")
  • Any firmware can be installed on any version of the device.
  • At the moment there is no evidence of any hardware differences between the Chinese / Russian / international versions.
  • In firmware with activated SSH access, you can change the language of the event voice by changing sound files.Instruction here.
  • The language of voice control without flashing cannot be changed.
  • Firmware differ not only in language, but also in functionality.

The difference between the functionality of the firmware(for example, version 1.0.4)
  • Attached ImageChinese- the most complete in terms of functionality.Supports Time-Lapse.There is a WDR switch in the settings (is it true that this setting gives at least something - it’s not clearhere is an example of freeze frames). Sounds the maximum number of events.Voice commands and interface - in Chinese. GPS coordinates and speed does not show.
  • Attached ImageInternational - No support for Time-Lapse.No WDR settings. Voiced only major events.Voice commands and interface - in English. GPS coordinates and speed are written in the form of metadata (in the presence of a GPS module and starting with firmware 1.0.5).
  • Attached ImageRussian - No Time-Lapse Support. No WDR settings. Voiced only major events.Voice control is not. Interface - in Russian. GPS coordinates and speed are written in the form of metadata (in the presence of a GPS module and starting with firmware 1.0.5).
9.2. Instructions - how and what to flash
There are two ways to update the firmware: manually and through the official application. The recommended update method is manual.

Through the official application is updated through the official channels - not recommended, because There is no possibility to choose the firmware, only what arrived via OTA is sewn, and this is a firmware with a clumsy voice acting and without the possibility of replacing it. If this method is still interesting for you -instruction here.

Manual firmware procedure
Method proven, but do not forget that all actions you do at your own peril and risk.
Important! Manual firmware occurs exclusively with battery power (even if the wire is connected). Before starting the firmware, it is recommended to make sure that the battery is working and charge it (keep the recorder turned on when there is an external power supply for at least 30 minutes).
In the off state (or in sleep mode) the battery DOES NOT CHARGE!
ATTENTION! Attempting the firmware when the battery is dead or discharged will be scanned by the recorder!

  1. Turn off the recorder and turn off the external power.
  2. Download the archive with the selected firmware.
  3. Folder "update"from the archive we put in the root of the memory card (as a result, going to the memory card, you should see the folder" update ", inside it - different files).
  4. We insert the card into the recorder, clamp and hold the mostextreme right knopand turn onbig long button, the right button is held until the inscription about the update appears, and then release.
  5. We wait until the screen goes out (usually no more than 15-20 seconds). We turn on the recorder with a large button and enjoy the updated firmware.

P.S .: if the registrar is not included as indicated in p.4, the registrar will simply start,deleting the "update" folder- will have to copy again.
9.3. Firmware

10. >About the display of speed and GPS coordinates
So, to display the coordinates from the GPS module and speed, you need:
  1. GPS module
  2. Firmware not lower than version1.0.5
  3. Application at least version1.2.0with GooglePlay or AppStore (Chinese application 1.2.2 does not fit)

The principle of operation from SW.snickm2:
"Speed ​​and coordinates are always written by default, these data are written to the video file as additional data, they are not superimposed in the frame as time and logo, they are simply in the video file.
If you view the video through the application, you see them, if through the player it is not.
If you want to publish a video with speed on youtube, you need to retake it from the phone screen by enabling playback in the application. "

For some reason, there is not a word in the specifications about how many frames per second this recorder has, but this is the most important parameter for recording at speed. The previous 70mai had only 30 fps, so I sold it and still use Yi dash cam 60 fps.

And the new 70mai Pro is not clear.

So also the Russian version.

Russian - this is good)) That's just the price tag pulled over a hefty.
And at the expense of quality, for example, I'm not worried. Regik is such a thing that if you use it only as a regik, it’s enough that from a couple of meters the numbers are readable, and the rest is pampering.
In the regions from Xiaomi, it is important for me and I like one thing - the ability to save files wirelessly and without a computer on a smartphone. And voice control is not crap at all.
But, this is my opinion and I do not impose it on anyone. Most likely I will take this region myself, but only if I sell the car together with the old xiaomi.

120 fps, as on a top-end Yi action camera, would certainly be better, because a car hiding from the accident scene will only appear for a moment in the frame and low resolution and low fps will not allow to recognize the car.

IMHO, 60 frames in comparison with 30 will not give any advantage.
A clear picture with a fast car in the frame will only be in the case of a very short exposure, and it does not matter which framerate is 30, 60 or 120. Under normal lighting, the exposure is much shorter than 1/60 or even 1/120
In case of insufficient lighting, exposure and 1/30 and 1/60 will give a blurry picture, and for 120 frames you also need a more sensitive large sensor so that the picture does not turn out dark.

Compare the same action camera at night at 30, 60 and 120 frames and you will be disappointed in 120 frames.
Xiaomi takes off terribly at night. Vehicle numbers will not be visible at 30, 60 or 120.
