2. Frequently asked questions
1) The system can’t start?
Usually this problem results from the incorrect power connection. Please follow below steps to
check the power connection:
1. Check the input power, whether the power wire is connected correctly, whether the ground wire is
connected back to the battery, and whether the fuse on the power wire is in good condition.
2. Check whether the ACC signal wire input to the power is with voltage higher than 7 V.
3. Check whether the device key is closed.
2) The MDVR restarts uninterruptedly?
Please follow below steps to check it:
1. Check whether the voltage of MDVR is insufficient. If the voltage is less than the start-up voltage of
the device, the device would always restart.
2. The problem in hard disk/SD card may cause the failure to start. Take off the storage part and check
whether it is broken down.
3) The device can’t record?
Usually this problem results from the storage disk or camera. Please follow below steps to check it:
1. Check whether the storage disk is installed, whether it is in good contact, and whether the disk can
be read normally in computer.
2. Check whether the storage disk is formatted. The storage disk should be formatted before normally
storing record files.
3. Check whether there is video signal input into the device from camera, and whether there is
video/image on the screen.
4) There is no voice in record file?
Please follow below steps to check it:
1. Check whether there is an external pickup, or whether the camera features with the function of
audio collection.
2. Access to Video Channel Settings, check if Audio is set on.
3. There must be video input into the channel for recording and it must record normally.

5) The GPS works abnormally?
Please follow below steps to check it:
1. Check whether the GPS antenna is installed correctly. There is a silk print logo on the GPS antenna
holder behind the host device.
2. Check whether the antenna receiver is sheltered. It should not be covered by any stuff, which may
cause it not to receive signals.
3. Environmental influence such as tree shades, being inside tunnel, driving near tall building or
elevated roads, thunderstorms or other weather influence, etc. can also cause signal loss or
receiving wrong signals.
6) The device can’t shutdown in ignition switch mode?
Please follow below steps to check it:
1. Check if the ACC line connection mode is correct; and check whether there is voltage on ACC
yellow line when the key is turned off.
2. If the device has been set with schedule recording, it can’t shutdown if it is still during recording time
of the task table.
7) How to install the WIFI antenna?
The antenna must be installed on unobstructed place of the roof, and be fixed with glue.
8) The device cannot be shut down when in ignition ON/OFF mode.
Check if the ACC signal wiring is correct and if there is voltage for ACC signal line after the key is
turned off .
If you have set timing recording, and at the current time it is still in task recording, the device may be
impossible to be shut down.
9) GPS anomaly.
Check if the GPS antenna is properly installed. There is silkscreen GPS identification on the GPS
antenna pedestal on the back of the MDVR device. Check if the antenna connector is blocked and
make sure the antenna connector not be covered by other things.
Trees block, being inside the tunnel, driving near tall buildings or viaduct, thunderstorms and other
environmental effects may also cause to receive no GPS signal or error signal.
10) No voice in video files.
See if there is an external microphone, or if the camera cannot capture audio;
Enter into the video channel settings, then check if the audio is open;
Ensure video input and normal recording, on which the audio recording channels must be based.
11) The device doesn’t record.
Make sure the storage part is installed and of fine contact, the data can be read on PC, and the
storage device is not formatted.
Check if there are video signal input to the main device, and whether there are video images in the
channel pictures.
12) Why has the MDVR device always been in a state of restart?
Check whether the MDVR device voltage is insufficient. If the device voltage does not reach the
start voltage, the device will restart.
Hard disk or SD card may cause the MDVR device unable to start. You need to remove the storage
device and then boot up to verify whether it is caused by the storage device.
13) Why the MDVR device cannot start?
Check the device input power to see if the power wiring is correct, if there is ground wire connected

13 - 13
back to the battery, and if the fuse of the power wire is n good condition;
Check whether there is voltage(more than 7V) on power input ACC signal wire; Check whether the
hard disk key is turned off.
14) What is the log in user name and password for new device?
The default user name and password are both “admin”. The device password can be set as empty.
15) In the ON/OFF of basic settings, the low voltage protection is 8V, why?
After testing, when the battery is lower than 8V, the voltage will lower down quickly. Therefore the
lowest voltage is set to be 8V. When it is lower than 8V, the MDVR device will recognize it as
external power-off and then enter into shutdown state.
