2Product Introduction
2.1 Product Overview
The MD500S is a four-channel mobile digital video recorder (MDVR) featuring high stability and supporting Advanced Driver
Assistance Systems (ADAS), Driver Monitoring System (DMS), video recording, and GPS tracking. Adopting the high-performance
processor and Android operating system, it can operate in vehicle tracking mode and video recording mode simultaneously and is
a core product of new-generation wireless vehicle video surveillance solutions that uses H.264 video compression or decompression,
GPS positioning, and wireless data transmission technologies.
The MD500S is small in size and light in weight and is characterized by internal GPS system and video processing system. With the
metal outer case, it dissipates heat more effectively and its rugged sturdy housing make it shockproof. This unit is specially designed
for mobile video surveillance for different types of vehicles, such as buses, long-distance coaches, taxis, logistics vehicles, special
purpose vehicles (such as armored cars), and private cars.

4Device Installation and Test
This chapter is intended for customers who use the MD500S MDVR for the first time, helping them configure and operate the device,
understand the basic functions of the device, and test the device alerts.
For more information about fast installing and using the MDVR, see the following sections.
4.1 Installing a SIM Card and Micro SD Card
Loosen the screws by using a screwdriver, remove the upper cover, insert the SIM card into the SIM card slot, and install the micro
SD card.

MEITRACK MD500S MDVR User Guide

4.2 Installing Cameras
Connect the AV-IN1 port of the device to the camera of the DMS, AV-IN2 port of the device to the camera of the ADAS, AV-IN3 and
AV-IN4 ports of the device to AHD cameras as required.
4.3 Installing the I/O Cable, Antennas, Speaker, and Microphone
1. Install the WiFi antenna, GSM antenna, GPS antenna, speaker, and microphone based on the following wiring diagram.
2. Connect to the I/O port based on the following wiring diagram.

MEITRACK MD500S MDVR User Guide
Copyright © 2021 Meitrack Group All rights reserved. - 16 -
Note:
a. The power cable, ground wire, and ACC cable must be connected. When the device detects that the ACC is on, the video
system starts operating.
b. Input 3 and input 4 are connected to the turning left and right signal light cables respectively. If not, when the vehicle turns
to the left or right, a lane departure alert is generated.
c. The speaker is connected to implement voice broadcasting of the ADAS and DMS, two-way calling, and two-way radio.
4.4 Setting the IP Address and Port By Using Meitrack Manager
If Meitack MDVR platform is used, the IP address is set to 67.203.15.7 and port set to 50005.
You are not advised to modify the default values of other parameters. For more information about how to configure the IP address
and port by using Meitrack Manager, see the Meitrack Manager User Guide.

MEITRACK MD500S MDVR User Guide

4.5 Platform Function Test
Before testing related DMS and ADAS functions, make sure that the device is online, video preview and two-way calling functions
are available, and the device is installed into the vehicle.
Visit the MS03 platform, right-click a device, and select Video Monitor.
If images are displayed as follows, it means that the cameras work properly.
Note: After you purchase devices, please apply to Meitrack sales team for a platform testing account.
4.6 Downloading and Using MTViewer Ai App (Android Only)
Visit https://play.google.com/store/apps/details?id=com.meitrack.adas_dms_controller, and download MTViewer Ai app.
Enable the device WiFi hotspot.
Start Meitrack Manager, enter the SSID and key of the WiFi hotspot, and click Set.

MEITRACK MD500S MDVR User Guide
Copyright © 2021 Meitrack Group All rights reserved. - 18 -
Connect your mobile phone to the device's WiFi hotspot.
On the WiFi settings page of your mobile phone, connect the mobile phone to the device's WiFi hotspot.
Note:
1、ACC needs to be activated when APP connects to MD500S.
2、When app is connected to MD500S WIF, the device will drop the line.
4.7 Installing the Camera of the DMS
The steering wheel of trucks and buses is low, so you should install the DMS on a higher location around the dashboard. It should
not be higher than the driver's eyes, and the angle between the installation location and the driver's face should not be higher than
30 degrees. Please ensure that the distance between the lens and eyes ranges from 60 cm to 90 cm. It is recommended that the
angle between the installation location and the driver's face should not be higher than 30 degrees.
If the DMS is installed into a car, you have to install it on the left or right position of the steering wheel. Because the steering wheel

MEITRACK MD500S MDVR User Guide

of the car is high. The angle between the installation location and the driver's face should not be higher than 30 degrees. Facial
features of the driver can be captured. The camera installation location can be adjusted by using MTViewer Ai app.
4.8 Installing the Camera of the ADAS
Please ensure that the installed ADAS does not blur the driver's vision. It is recommended that you install the ADAS in the middle
of the distance between the uppermost sides of two windshields. The installation location is shown in the following figure:
Note: After the ADAS installation is finished, adjust the camera location by using MTViewer Ai app to improve the accuracy of the
ADAS.
Step 1: Adjust the installation location of the camera of the ADAS.
Step 2: Adjust the yellow horizontal line to the horizon and yellow vertical line to the middle of the road, as shown in the following
figure.
