10. Trouble Shooting.
1. Q : After connecting the DVR power, no video output, No.1 and No.2 indicators
lights on panel flashing alternately.
A: The No.1 and No.2 indicator light is “Power” and “Run” . If the 2 indicators lights are flashing
alternatively , the DVR missed the ignition signal, please check if the yellow line of the input power
lines has connected with the power positive level, or if it’s the same as the setting of the effective
electrical level in menu settings. (The factory default settings set the high level effective,that is,
it is effective when the yellow ignition signal line is connecting with the power positive level .)
2. Q: As SD cards’ capacity limited, how to make the videos’ time expand to meet the
requirements of the customers?
A: Reduce the video frame rate, video quality and record by Composite Mode.
1. Set the Channel Mode in the "Video Settings" menu to Composite Record (see 3.5);
2, Enter the "Video Parameters settings" menu, select a lower vide o quality, while reduce the
frame rate to 12 frames / sec or less. Generally, it can expand the recording time to 4 to 10 times
longer or more by using the above method.
3. Q: when using the DVR, ScreenTip appears "read only error ".
A: Please check if the SD card is write-protected, if so, please move the picks to the non - write
protected.
4. Q: What is a high level, what is low level?
A: Generally, there are two electrical levels in the car, the power and the ground. Automotiv e
power voltage with 12V and 24V, we generally call it high level, not the specific voltage value.
Ground of Vehicle is the ref erence level, accurately is battery negative electrode. We generally call
it low level. For cars with negative switch control (the main switch cut off the connection of the
battery cathode and car chassis ground), the chassis ground connects to the battery anode
through a certain resistance, the chassis ground is not a reference ground anymore. Please see
the Appendix in the back, including the potential analysis diagram against cars with negative
switch control.
5. Q: Respectively, what’s the voltage reference range of the high and low level in
the DVR?
A: The voltage range of low level is DC 0V~3V, the high level is DC6V~32V.
6. Q: Why doesn't the DVR remote control work?
A: Please make sure the battery in the remote control is still good, or try to change a new battery .
And make sure aiming the remote control at infrared receptor window on the front panel of DVR.
7. Q: SD cards or hard drives are OK, but the video recording doesn't work, what
should I do?
A: Please make sure if the default setting of Record Mode is changed from "Automatic" to" Off ",
and whether to modify the DVR to scheduled record mode and the current time is not within the
www.supercircuits.com MDVR21SD_RM
59
Page 60
time period you set.
8. Q: Do your SD Card DVR support the capacity of 64G and above SDXC card?
A: The DVR support the capacities of 64G and above SDXC cards, but currently, DVR doesn’t
support for ExFA T file system completely , we suggest that you format the SDXC card to F A T32 file
system under Windows system before using. You can also download free version “Partition
Manager” or other partition software from the Internet, which can make the process faster and
simpler.
9. Q: when the SD card inserted the DVR for recording, live images or playback
visual will come to a frequent halt.
A: Please make sure that if your SD card or USB’s writing speed is enough. When the recording
medium’s writing speed is not e nough, it w ill af f ect the continuit y of liv e vi deo and the r eal-time
recorded video. Generally the SD card DVR can directly support two kinds of media:
1). SD card. With good writing speed and quality, there are Kingston, T ranscent etc. brands on
the market, It is more reliable for its conventional speed values of Class x and op eration, it will not
pause even with the highest record data rate on this machine. While other bra nds’ SD car d with
the uneven quality and serious counterfeit, customers come to meet this problem usually, the
fault disappears after replacing the SD card.
2). USB disk. Because of the cost sensitive reasons, most of USB disks sold on the market are
the products of the USB1.1.Their speed can not meet the data rate of the requirements of the
DVR. Please replace USB2.0 products for the faster speed.
10. Q: Do internal real time clock of the DVR maintained by batteries? If so, how
long will it last?
A: Rechargeable batteries are used for DVR internal real time clock. If the battery is fully
charged and DVR is completely disconnected from the power supply, internal real time clock can
probably last for 1 month.
11. Q: How to take out the SD card from the DVR safely?
A: It’s similar to use a SD card or USB disk on the computer, stop the file opera tion before the
extraction, so as to ensure that the internal files of SD card or USB disk will not be destroyed or
lost. This SD DVR provides a simple and safe wa y to eject the SD card: before eject the SD card,
please press a small button on the right of the SD card, when you see the yellow indicator light
goes OFF, you can eject your SD card safely.
12. Q: what do the 5 indicator lights representative on the panel of the DVR?

The fifth yellow indicator light on the panel is SD card recording indicator light, if this light on,
it means DVR is recording.
13. Q: what kind of player software should use to play back video slots in SD card on
the PC? Why some of them don’t play normally?
A: The SD DVR recording files is a standard AVI format, video stream compression standard
is senior H. 264.
1. SD DVR has its own player software, including many special additional feature, such as
playing continuously, fast forward playing, and other quickly locating recording and playing.
2. The recorded f iles also support general players. Such as VLC (version 1.0.0 and above,
free open source software, can download from the internet), Media Player Classic(version 2009
Build: 3.9. above). Older Storm Audio can only support for video of 720x576 - resolution, when
playing high resolution (1280x1024) recorded video file of Composite Mode, it can't display all the
images, images on the right and below the video will be cut-off.
14. Q: How to upgrade the SD DVR program?
A: 1.Copy the update package (Suffix ".tar" files) to the root directory of SD card (or USB disk).
Be careful not to extract.
2. Insert the SD card (USB disk) to DVR, after the machine detects the SD card, press menu
to upgrade: System settings -> system information (version, upgrade etc.) -> upgrade
-> upgrade your current application -> select the upgrade file -> OK
(Note: press the menu key to enter the next level of menu items. Normally you can
complete the whole upgrade operation by using the menu key only.)
15. Q: Do your DVRs have RS485 control PTZ functions?
A: For very few of car application using PTZ contr ol, mobile DVR factory default is without the
www.supercircuits.com MDVR21SD_RM
61
Page 62
RS485 control PTZ functions. If you do need PTZ control function, please contact sales when
ordering.
16. Q: I bought the mobile DVR with PTZ control function, but it has no response
after PTZ connecting.
A: After you have confirmed your machine already has PTZ contr ol f unction, you m ay t est y our
control functions in accordance with the following:
1, Exchange the two lines of 485A and 485B, to see if they are connected wrong;
2, Confirm if the PTZ Protocol is right;
3, Confirm if the PTZ Address is right, our default is 1, trying to adjust to 0 or 2; generally
the PTZ address code is 1. The address code needs to be changed when multiple PTZ devices
connected. In addition, the address of each PTZ device cannot be duplicated, if you have 4 PTZ
devices, you can respectively set them to address 1, address 2, addresse3 and address 4.
17. Q: what is the difference of Separate Recording Mode and Composite Recording
Mode?
A : Separate Recording Mode, that is, the DVR compress each of front-end camera's
image and audio separately , if it is a 4 - channel DVR, yo u will have 4 real-time D1 image AVI files,
which is recorded on the SD card or USB disk at the same time.
Composite Recording Mode, that is, to composite multiple front-end camera images into
a high - definition image (such as 1280x1024), and then compress the image w ith video encoder,
at one point in time there has been only 1 high - definition AVI files recorded on SD card or USB
disk.
Recording by Separate Mode can extr act AVI file of each camera separately, but we can get
recorded file of combination image with 4 cameras by Composite Mode.
The default recording mode of the SD DVR is the Composite recording Mode, its advantages are
high-definition, storage space saving and convenient playing.
18. Q: How long will my SD card of 32GB record?
A: we have provided recording volume calculator software on the accessory CD, which can
run on a PC. Or in the record settings of the host, select the different settings, such as quality,
frame rate, it will show the total recording time of your c urrent storage module below the screen.
Generally speaking, recording time not only relates with picture quality, frame rate, but also
relates with frequency of scenery changing in front of the camera lens. For some static image, the
real recording time will be considerably longer than the calculated time.
19. Q: Why can't I use VLC or other software to see the real time image through the
network?
A: The SD DVR turns off the network function by default, if y ou need network, please set the
"Network" to "on" in the "Record - Video Parameters ".
20. Q: Why is the bottom section of the screen with no image or video corruption?
A: Firstly , mak e sure the DVR’ s video system and camer a system are the same, for example,
www.supercircuits.com MDVR21SD_RM
62
Page 63
it will occur when the DVR settings is P AL system, while the camer a is NT SC system. Conv ersely,
if the DVR is set with NTSC system, scrolled fault images also occur when connecting a camera
with PAL system.
21. Q: when retrieving record files on the machine, only find the record files of
channel 1, how to find the files of the other channels?
A: Press the <left> or <right> keys on the remote control to switch other channels to
retrieve record f iles. On the top right of the screen will display which channel the current f ile
belongs to.
22. Q: what is “Power OFF Delay”?
A: Users who need to install DVR often want the DVR to record the images inside and outside
the car for a while after the driver turn the engine off. That is, DVR cannot be turned off after
engine is shutdown, it should be off after recor d continuously for the specified period of time. This
time is called “Power OFF Delay” time, such as 30 seconds. Y ou can set the time you need on "Car
Settings – Power Off Delay ".
When the users who need “Power OFF Delay” function, the positive lev el of the DVR and the
ground should be connected directly (through the fuse) to the cathode and anode of the car
battery, at the same time attach car ignition signal line to the ACC of the car.
Of course, the time of “Power OFF Delay” cannot be set too long, because after the engine
shutdown, mobile DVR entirely depend on the power of the car battery to work, we should
prevent the vehicle can’t start correctly next time if the mobile DVR drained the energy of the car
battery.
23. Q: Why does DVR keep alarm when I set the motion detection, even if the image
moving is not obvious?
A: First, please make sure that if the sensitivity settings of the motion detection are correct,
sensitivity is divided into 9 levels. The ninth level is the highest sensitivity; the f irst level is the
lowest sensitivity.
Second, make sure that if your camera system (PAL system or NTSC system) match the
stroboscopic lighting devices such as fluorescent lights. PAL system is 50Hz system, NTSC system
is 60Hz system, and there are also two kinds of working frequency of power grid: 50Hz and 60Hz.
if a PAL camera of 50Hz work under the fluorescent lights driven by the power grid of 60HZ,
images will appear frequency difference flashing of 10Hz, this will led system to think scenery
brightness is changing continuously, and motion detection alarm is based on the changes of
scenery brightness to work, this will triggered motion detection alarm. Conversely, a false alarm
