Appendix 2: Common Problems and Treatment
Q: What can I do when I find a problem with the product, but I cannot solve it by myself?
A: Contact your supplier. Take note of the model and software version number then submit
a detailed description of the problem to the technical support engineers to investigate. The
more details of the problem you have submitted, the more convenient it will be for the
technical support engineers to find out the problem.
Q: There is no video output from the vehicle host device?
A: 1. Check the host’s status (on), if only a blue light is on it means the host is on standby
and has not been started up yet. Meanwhile check whether the host’s power cords (red &
yellow) are in power supply status or not. If only one cord is supplying power, the device
is unable to start up.
2. Check the power status of the display screen, as well as checking whether the display
video has been switched to AV.
3. Check the connecting status between the host’s video output cable and display screen.
4. Check the LOCK status, it must be locked before a normal start up.
Q: What do I do when the car host video input interface is different from the camera output
interface?
A: The car uses a 4PIN type while the camera uses a BNC or aviation head type. If needed
use a conversion head or wiring based on standard corresponding according to the cable
sequence defined by the car host.
Q: The device does not conduct video recording after it is turned on and the SD card has
already been installed?
A: 1.Check whether the SD card has been formatted or not after installation, because an
unformatted SD card cannot be used. Enter System Menu - System Tools - Device Format
to format the newly installed SD card.
2. Check to see whether the video channel is closed or not and if a timer recording has
been set. It will not record any video when it is not within the video recording time period.
3.Check to see if the SD card has been inserted properly. Also see if the SD light on the
front panel is on or not.
Q: The video file is missing or there is no video file within a certain period of time, what do
I do?
A: 1. Determine the time period by analysing the final video file and the first video file after
recovery.
2. Confirm whether the host is not on during that period of time, such as when the driver
is parking, loading and unloading goods while the host is not set by video delay.
Q: The car PTZ cannot be controlled, it cannot rotate up and down?
A: Check whether PTZ protocols and baud rate are set correct, address codes are
corresponding. Maximize the video of the channel when controlling the PTZ, for example,
when you control the second channel, it must maximize the screen of the second channel
image to control it.
