FAQ
Q: What can I do when I found a problem with the product, but I can not solve it by myself?
A: Take note of the model and software version number, then submit a detailed description of the problem to the technical supporting engineers to analyze; the more detailed you have submitted, the more convenient for us to analysize.

Q: How about when there is no video output from the vehicle host device?
A: 1.Check the host’s turn-on status, if only a blue light on, it means the host is in standby status and has not been started up yet, meanwhile check whether the host’s power cords red & yellow cords 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 supply status of display screen, as well as check whether the display video has been switched to AV status.
3 Check the connecting status between the host’s video output cable and display screen.
4 check whether the lock status of the host’s LOCK, it must be locked before normal starting up.

Q: How to do when the car host video input interface is different from the camera output interface?
A: The car uses 4PIN type while camera uses BNC or aviation head type, if not in correspondence, please use conversion head for connection or wiring based on standard corresponding according to the cable sequence defined by the car host.

Q: How to do when the device does not conduct video recording after it is turned on and SD card has already been installed?
A: 1.Check whether the SD card has been formatted or not after installation, because 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 video channel is closed or not, whether set a timer recording or not, it will not take video when it is not within the video recording time period.
3.Check the SD card inserting status and whether the SD light on front panel is on or not.

Q: The video file is missing or there is no video file within a certain period of time, how to do?
A: 1. Determine the time period by analyzing the final video file before missing 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 halfway parking, loading and unloading goods while the host is not set by video delay.

Q: When car PTZ cannot be controlled, it cannot rotate up and down, how to do?
A: Check whether PTZ protocols and baud rate are set correct, address codes are corresponding or not, whether have selected to maximize the video of the channel when control the PTZ, for example, when control the second channel, it must maximize the screen of the second channel image to control it.GPS-related issues

Q: GPS module exists but no coordinate information?
A: 1.Check whether GPS module exists, if it does not exist, check whether the hardware is installed or in a good contact.
2.Make sure that the GPS antenna contacts are good, whether the antenna is broken, it is recommended to be located in places with strong signal, note that some car glass shielding film will block GPS signals;
3 If the test is in the room, the signal of GPS antenna in the room will be obscured, it is recommended that the GPS antenna is placed outdoor.

Q: Deviation of GPS location on map?
A: It means the signal is valid if the GPS module already positioned, there may many reasons for the deviation, such as government restrictions, permissible error, GPS signal interruption, etc; the actual satellite map may have deviation for security reasons, general map can solve the problem by using GPS correction.3G wireless module

Q: If use the 3G wireless module for dial-up, what do I need to pay attention to?
A: 1. Choose the built-in wireless module WCDMA or EVDO, corresponding module settings are not the same, the modules supported by different machines models are not the same, so please make sure whether your module and SIM is in correspondence. Do not use telecom SIM card on WCDMA machine;
2.Check whether the settings of Server IP and port are correct, whether 3G signal is strong enough for dialing, and then check whether the 3G dial-up is successful or not.
3. When dialing is unsuccessful, please check 3G antenna is in good contact or not, the dial up may fail because of weak signal, moreover, please check whether the SIM card has enough traffic, if no traffic, dial-up will be unsuccessful.

Q: When 3G has neither report nor video , what should be done first?
A: Press INFO key to enter the system information page, check whether the SIM card exists and view the signal strength as well as dial-up status, whether the antenna is in good contact, and then check the SIM to see whether it is out of traffic, the most basic judgment is to replace the SIM card. If the dial up failed with signal, then check whether the settings of center number and the port are correct. Moreover check whether the device number of the product is already occupied.

Q: 3G signal is intermittent, video is jammed?
A: At present the signal coverage of WCDMA and EVDO is rather wide, however, there are some mountainous districts without signal coverage, and some suburban areas have weak signal due to the local network constraints, then it will be jammed during watching of video, or video cannot be watched at all, the greatest impact of this situation is from the local network; Moreover check whether the frame rate setting of sub-stream is too high, because the video may also occur such situation when the network is poor and frame rate setting is high.

Q: Why the vehicle and video cannot be seen in CMSviewer client when the device has been started?
A: At first make sure the central registration server is switched on and on the net, then check whether the host device number has been occupied to cause conflict, secondly check whether the settings of server-centric IP and port are correct; devices report to the center via the built-in 3G module or via WIFI. If via built-in 3G, please check whether selected the correct type of built-in 3G module, for example, WCDMA and EVDO module needs the support from corresponding SIM card, check whether the antenna is in good contact; If it still can not report when above all are checked, enter into the system information page to view dial-up. If dial-up is not successful, look up whether the setting of data access point and center number is correct. If all ultimately fail, please collect as much information as possible to submit to the technical supporting staff for analysis, the more data provided, the more convenient for technicians to solve the problem.

Q: The device is online, but why can I not see the video image?
A: Please set lower sub-stream to transmit image, the blocked or slow transmission speed situation may occur when the sub-stream frame rate is set very high and be affected by network uploading limit; poor network signal or intermittent will seriously affect the video transmission.

Q: The device is properly reported on CMSviewer, but the videos cannot be seen after using for some time?
A: Firstly check whether the host side displays dialing, if it keeps the dialing status, it may be because the flow of the SIM card has run out, replace the SIM card to test; Secondly query whether the host device number has been modified by the driver, the host with modified device number needs to be resubmitted to add vehicle information; thirdly, if it still does not work by changing the card, it will need to check whether the host’s 3G module fails.
