4Fast Installing and Using the MDVR
Perform the following nine steps to fast install and use the MDVR:
1) Loosen the screws and insert the key to open the SD card lock.
2) Insert the SIM card into the SIM card slot.
3) Install SD cards.
4) Connect four cameras, the display, handset, GSM antenna, WiFi antenna and GPS antenna.
5) Connect the power cable (including the VCC, GND and ACC cables) to the external power supply. (The ACC cable must be
connected to the positive terminal of the external power supply. Otherwise, the MDVR cannot be started.)
6) Set the IP address and port of the platform.
7) Set the data transmission network.
8) Set the login user name and password.
9) After logging in to the platform, you can implement video surveillance, search videos, and make a call.
4.1 Installing the MDVR
(1) Loosen the screws and insert the key to open the SD card lock.

MEITRACK MD522S User Guide
Copyright © 2019 Meitrack Group All rights reserved. - 17 -
(2) Install a SIM card and two SD cards, and then lock SD cards. (Note: You must lock the card cover by the key after closing it.
Otherwise, the recording function fails to be started.)
(3) Connect four cameras, the display, handset, GPS antenna, GSM antenna, WiFi antenna, and power cable.
Plug the power cable in the PWR interface.
Plug the four cameras in the AV-IN1, AV-IN2, AV-IN3, and AV-IN4 interfaces.
Plug the display in the AV-OUT interface.
Plug the handset in the MIC&SPK interface.
Connect the WiFi antenna, GPS antenna, and 3G/4G antenna to the MDVR. (If the WiFi antenna is not connected, the WiFi
function will be unavailable.)
(4) Supply power to the MDVR and connect the external power supply to the ACC cable. (Note: To enable the recording function,
ensure that the ACC cable is connected to the positive terminal of the power supply and SD cards are locked.)

MEITRACK MD522S User Guide

(5) After the external power supply is connected, the initialized MDVR will automatically record videos, and the display will be
turned on automatically and play live videos.
4.2 Configuring the MDVR by Using Meitrack Manager
After the MDVR is installed, connect it to a network and server. You can configure the MDVR by using any of the following

MEITRACK MD522S User Guide
Copyright © 2019 Meitrack Group All rights reserved. - 19 -
methods: Meitrack Manager software, SMS, and platform. In this section, I will show you how to use the Meitrack Manager
software to fast configure the MDVR.
You need to install Meitrack Manager first. (Visit www.meitrack.com to download the software). After the installation is
completed, connect the USB cable to a computer, and then perform the following steps to configure the MDVR.
(1) After the MDVR is installed, connect it to the network and server. You can configure the MDVR by using any of the following
methods: Meitrack Manager software, SMS, and platform.
Set the IP address and port for uploading positioning data, IP address and port for uploading video data, and the user name and
password of the FTP server:
SMS configuration:
Send the following command to set the IP address and port for uploading positioning data:
0000,A21,1,183.234.68.78,8501,APN(for example, internet),APN_USER,APN_PASSWORD.
(2) Set the IP address of the FTP server. Video data will be uploaded to the specified FTP server.
(3) Set the network.
There are three network connections: 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.
WiFi configuration:
As shown in the following figure, enter the WiFi SSID and password and click Set. The WiFi network connection is set successfully.
You can click Refresh to search the WiFi list nearby.

MEITRACK MD522S User Guide
Copyright © 2019 Meitrack Group All rights reserved. - 20 -
Ethernet configuration:
Enter the IP address, subnet mask, gateway, active DNS server and standby DNS server.
Cellular network configuration:
Enter the APN, APN user name and APN password, and click Set to save the settings.
(4) Check whether SD cards are installed properly. When you use the MDVR for the first time, if the system detects format errors,
SD cards will be initialized automatically. If "no error" is displayed as follows, it means that SD cards are initialized successfully.
4.3 Logging In to the Platform
Visit https://mdvr.trackingmate.com/, enter the user name and password, and log in to the platform.
