inside the vehicle; it should keep 6inches (15 cm) from other objects when installed in plane, in
order to facilitate vehicle; it should keep 6inches (15 cm) from other objects when installed in
plane, in order to facilitate air circulation and heat dissipation; it cannot be installed in a closed
space, such as the vehicle trunk. It is recommended to be put straight up which can extend the life
of hard disk, while side-mounted can easily damage hard disk; external wire must have enough
interval and protection by fire –retardant pipe, to ensure that the wire will not be bent or leakage
due to vibration and wear; please ensure that the device is away from the heat source on the
vehicle, and it is prohibited to place any debris on the device.
5: Device safety:
Make sure that the passenger or the driver cannot interfere and damage the piece of device,
cameras, wires and other accessories do not install the device near any restricted vehicle
components, cameras, accessories and wires, must make sure that the vehicle is stationary during
the installation process to prevent the device from falling.
1.This device includes electronic
components, please handle with care
during transportation.
2. Installation and maintenance must be
performed by professionally qualified
persons.
3. It cannot be installed in any eroded
places by rain or other liquid
4. It cannot be put under any heavy stuffs
5. Keep it away from heat, dust, and
strong magnetic field, do not directly flush
6. Do not replace any module when main
body is powered on.
7. Do not open or disassemble the device
without guidance of professionals.
8. Device output power shall not lap any
non-recommended

1.2 The MDVR products application connection
diagram
Please refer toFigure1-1，This product can be used for video surveillance or remote
monitoring which applies in common or special vehicles such as buses, logistic vehicles, trucks,
long-distance coaches, taxis, tankers, cars, school buses, police cars, patrol cars. In front-end it
mainly collects video signal by dedicated automotive camera ,then transmit to the MDVR host via
a special video cable to do the video compression and image processing, which is locally storage
in SD card .it can also be remote monitored or remote video recorded and downloaded by the
remote client if with 3G models .It can real-time locate the vehicle position;Figure1-1 schematic
diagram is a common model of application, each function during actual use will vary with the
presence of module.

As shown by below pictures, one end is 6PIN white plug, which will
be connected to the 6PIN power input connector on the rear panel of the
device, the red and black wires are connected directly to the vehicle battery
or the gathered electric which go through battery and fuse; red wire links to
firing wire, the main device automatically start up when the vehicles key is
turned on, and shut off automatically after delay when vehicles key is
turned off; yellow wire links to the position when vehicles key turn on all
dashboard lights(the position before vehicle starts the motor).

B:Audio&Video Wires
Above are the general ways of MDVR rear plate interface
wiring,4PIN testing wire is only used in the test which is not
recommended to be used in installation, it is recommended to use 4PIN
audio and video output, while the φ 3.5 phone Jack interface in the front panel can also
output audio and video .Its peripheral interface can be optional 3G/GPS, which then will need to
use 3Gantenna and GPS antenna, as shown in Figure2-8
C ： Alarm input&output
This device has 4 alarm input and one alarm output interface ,alarm
input detection are all level detection which can be accessed by a variety
NOTE:
1:Need to make sure the battery voltage is between 8V-36V before
connecting, otherwise above voltage will burn out the device;
2:Pay attention to the insulation among the power cord after connection to
prevent the short circuit of the power cord which will burn out the battery and
other electrical equipment in the vehicle;
3:It is recommended to link the yellow wire to the firing wire, otherwise the
device will not support the delayed shutdown;
4:The installation of vehicle-mounted is recommended to directly take from
battery positive and negative, or pick from the main electrical with fuse, do not
use ground because ground will produce negative pulses which will interfere
with the normal operation of the host. The diameter of positive and negative
power cord must be more than φ1.5mm;
