(However, the format and resolution of cameras connected to the AV-IN1 port and AV-IN2 port must be the same, and the format and resolution of cameras connected to the AV-IN3 port and AV-IN4 port must be the same. For example, if the AV-IN1 port is connected to a D1 camera, the AV-IN2 port must be connected to a D1 camera and the AV-IN3 or AV-IN4 port can be connected to another type of camera.)
•  MD811H/MD822S: 8-channel AHD cameras. D1/720P/1080P and self-adaptive PAL and NTSC formats are supported. The type of the four cameras connected can be different. (However, the format and resolution of one camera connected to an AV-IN port must be the same as that of the other camera connected to the AV-IN port.)
• MD533S: 2-channel AHD cameras. D1/720P/1080P and self-adaptive PAL and NTSC formats are supported. The type of the two cameras connected must be the same.

The MDVR Does Not Support Video Recording After the Engine Is Off. Why?
The MDVR supports the parallel running of two systems. When the ACC is off, the GPS system continues to work and the DVR system stops work to reduce the device’s power consumption.

How to Set the Working Time of the MDVR After the Engine Is Off?
After the engine is off, the DVR system continues to work for 10 seconds by default. If the device is equipped with standard firmware, the maximum working time of the DVR system can be set to 65535 seconds. If longer working time needs to be set, customize the firmware.

if the Engine Is Not Started, Will the Vehicle Battery Be Quickly Consumed By the Device?
After the engine is off, wait for five minutes, then the device enters sleep mode. In this way, the power consumption is lower than 10 mA and excessive consumption of the vehicle battery will not happen.

After the MDVR Is Connected to a Display, a Noise Can Be Heard. Why?
The power of the external power supply is not enough. Please try to increase the input voltage and current.

Power Consumption
Start the host audio and video: about 8 W Connect to eight cameras: about 24 W in the daytime (a display connected: 29 W); about 32 W at night (a display connected: 37 W) Connect to a single camera: 50–100 mA in the daytime; 200–250 mA at night

Data Usage

•  The data usage varies depending on the size of data uploaded by the device. Uploaded data contains audio and video data and positioning data.

• Video data calculation formula: Bitrate (Kbs)/8 x Number of channels /1024 = Data usage per second (MB)
  Note: The formula is applicable to scenarios that the device is monitored continuously via the platform or uploads video files continuously. It becomes unavailable when functions of monitoring and FTP uploading are enabled at the same time or data usage is calculated by using special calculation methods.)

• Positioning data calculation formula: 0.2 KB x 3600/GPRS interval x 24/1024 = Data usage per day (MB)
  Note: The formula is applicable to general use scenarios. It becomes unavailable when commands are frequently sent to read and write data, photos are frequently uploaded, or data usage is calculated by using special calculation methods.

Video Storage Space
Calculation formula of disk space for video recordings in one channel within one hour (MB/H): (Bitrate of storage streams/1024) x 3600/8/0.9 = Size of video recordings For example, when the bitrate is 7072 Kbs, the size of video recordings in one channel within one hour is 1500 MB. If the size of the SD card is 512 GB and only one camera is connected, the video recordings can be stored for about 350 hours.

The MDVR Fails to Detect Any Hard Disk or SD Card or Detects That the Hard Disk or SD Card Is Abnormal. Why?

•  Please ensure that the hard disk or SD card is installed properly.
•  Check whether the SD card is read-only.
• Replace the hard disk or SD card and try again later.

How to View Video Recordings Stored in the Hard Disk or SD Card?

•  Remove the hard disk or SD card from the MDVR and insert it into a computer. Then view video recordings via MT Player.
•  Playback videos via the MS03 platform.

Why an SD Card Reader Is Required?
Only when an SD card is detected as a portable device on a computer, videos can be viewed via MT Player. Sometimes an SD card is detected as a disk. Therefore, you had better prepare an SD card reader in advance.

After the Hard Disk or SD Card Is Inserted Into a Computer, a Formatting Prompt Appears. Why?
After the hard disk or SD card is installed, it enters a working state. After it is inserted into a computer, the computer may detect that it is abnormal. Do not format the hard disk or SD card. Otherwise, video files stored in the hard disk or SD card will be deleted.

After the Hard Disk or SD Card Is Inserted Into the MDVR, It Is Formatted Automatically. Why?
When the hard disk or SD card is inserted into the MDVR for the first time, if the system detects format errors, the hard disk or SD card will be formatted automatically and enters working state. If “no error” is displayed on Meitrack Manager, it means that the hard disk or SD card is initialized successfully.

No Video File Is Searched on MT Player. Why?

•  Check whether video files are stored in the hard disk or SD card and the video recording function is enabled at the specified time period.
• Check whether the hard disk or SD card has enough space to store video files. For example, if one 1080P camera records videos for one hour, more than 1 GB of memory is occupied. If an SD card with small memory is used, no complete video file exists. (By default, when a video is recorded in one channel for 60 consecutive minutes, a video file is generated.) .

Video File Format

How to Convert a .avmsg File to a .mp4 File
MT Player can be used to convert a .avmsg file to a .mp4 file and supports this video format conversion only.

The Video Format Cannot Be Converted via MT Player. Why?
MT Player must be installed in non-system disks. If it is installed in C drive, the video format conversion function becomes unavailable.

When the Disk Is Full, Can Video Files Be Stored Normally?
After the disk is full, users can stop recordings or replace old videos with new ones (default).

Storage Medium and Maximum Storage Capacity Supported

•  The MD533S supports one micro SD card.
• The MD522S or MD822S supports two SD cards.
• The MD511H or MD811H supports one SD card and one hard disk.
• A hard disk supports up to 2 TB, while a micro SD card or an SD card supports up to 512 GB.

MT Viewer Fails to Be Connected. Why?
Enable the hotspot function of the MDVR, connect your phone to a WiFi hotspot of the MDVR, and then start MT Viewer. If MT Viewer still fails to be connected, exit MT Viewer and then start it, or use another mobile phone to try again.

Default Storage Path of Video Files Downloaded By MT Viewer?

1.  The storage path of video files is Downloads/MTViewer.
2. The storage path of photos is DCIM/MTViewer.

The MDVR Cannot Be Started. Why?

• Check whether the cabling is correct and the external power supply works properly.
•  Check whether the electronic lock of the device is locked (excluding the MD533S).

Network Connection
There are three ways to connect a network: cellular network (3G/4G), WiFi, and Ethernet. Ethernet is the best choice, WiFi is the second choice, and a cellular network is the last choice. It means that if the MDVR is connected to Ethernet, the WiFi and cellular network will be disabled.

Route Mode Settings
The route mode supports four options: Auto, GSM, WiFi and Ethernet. If Auto is selected, the MDVR will first detect the Ethernet network, then the WiFi network, and finally the GSM network.

A Cellular Network Fails to Be Connected. Why?
No GSM signal is detected, the GSM antenna is not installed properly, the GSM antenna is damaged, GSM jamming is detected, the APN settings are not correct, the SIM card does not have sufficient balance, or the GPRS function is not enabled.

The WiFi Network Fails to Be Set or Connected. Why?
The WiFi module is not started (When the ACC is on, the WiFi module starts to work.), the WiFi SSID or password is not correct, the WiFi antenna is not installed properly, the WiFi antenna is damaged, or the WiFi router network is abnormal.

Ethernet Connection
The DHCP is not enabled for the MDVR, so you have to enter a fixed IP address and related information. Please ensure that the settings of the IP address, subnet mask, gateway, active DNS server, and standby DNS server are correct. Note: The MD533S cannot be connected to a network through a port.

The MDVR Is Online, But It Does Not Support Real-Time Previewing and Playback of Videos. Why?

1.  When the ACC is on, the device is started.
2.  The hard disk, SD card, or micro SD card is abnormal.
3.  The electronic lock of the device is not locked (excluding the MD533S).
4. The MS03 platform and streaming media server are abnormal.

IP Address and Port Configuration

The MDVR supports two IP addresses. Please ensure that the IP address and port are set correctly.

How to Automatically Upload Video Files to a Specified FTP Server
An FTP server is required to store video recordings and photos from the MDVR. Set the FTP server IP address, domain name, port, user name, password, and remote directory (IMEI).

As shown in the following figure, if FTP for an alert is selected, when an emergency alert is triggered, a video will be recorded, a photo will be taken, and the video and photo will be uploaded to the FTP server automatically.

Minor stream files can be stored in the MDVR and automatically uploaded to the FTP server.

What Are OSD Parameters?
OSD parameters are showed on the video screen, such as the license plate (device name), latitude, longitude, driving speed, continuous driving time, and alert information.

What Is the Difference Between the Local Time Zone and the GPRS Time Zone?
The local time zone indicates the time characters shown among camera OSD characters or among SMS alert texts. GPRS time zone: The time of uploading positioning data is based on GMT 0 (London time). You can set the GPRS time zone as required. The MS03 platform can automatically detect users’ time zone, and the GPRS time zone does not need to be changed.

What Is the Difference Between H.264 and H.265?
When the image quality of two videos is the same and their bitrates are the same, the storage space of the video adopting the H.265 standard is 50% less than that of the video adopting the H.264 standard. If the storage space of two videos is the same and their bitrates are the same, the image quality of the video adopting the H.265 standard is 30%–40% higher than that of the video adopting the H.264 standard.

What Is the Video Packaging Time?
Indicates the playing time of each audio or video file (excluding alert videos). Audio and video files are packaged based on the preset time.

What Is the Pre-recording Time and Recording Delay Time?
The pre-recording time indicates the recording time before an event is triggered. This time ranges from 0 to 900 seconds.

The recording delay time indicates the recording time of audio or video recordings after an event is triggered. The default time is 300 seconds.

For example, the pre-recording time is set to 600 seconds, and the recording delay time for an SOS event is set to 300 seconds. When an SOS event is triggered, a video recording lasting 900 seconds will be stored.

How to Fast Detect the Network Status?
Run Meitrack Manager, choose Network > Check Network Information.

Why Auto Reboot Is Required for the Device?
If the Linux system of the device runs for a long time, the device may lag due to a shortage of memory. In this way, users can set auto-reboot to release the memory, thus improving the working efficiency of the device. The default auto-reboot time is 1:00 am every Saturday.
