8. Trouble Shooting.
1. Q : After connecting the DVR power, no WiFi AP SSID available, 5 and No.6
indicators lights on panel flashing alternately.
A: The No.5 and No.6 LED 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, resolution and bit rate, please see 5.2.
3. 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. Automotive
power voltage with 12V and 24V, we generally call it high level, not the specific voltage value.
Ground of Vehicle is the reference 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.
4. 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.
5. 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
time period you set.
6. 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 ExFAT file system completely, we suggest that you format the SDXC card to FAT32 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.
7. Q: when the SD card or USB disk inserted the DVR for recording, live images or
playback video (through WiFi) 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 enough, it will affect the continuity of live video and the real-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, Transcent etc. brands on
the market, It is more reliable for its conventional speed values of Class x and operation, it will not
pause even with the highest record data rate on this machine. While other brands’ SD card with the
