Frequently Asked Questions About Car Video Recorders
Dec 19, 2018


When the host is normally started, a short beep will be announced. If the sound of the long beep is declared cyclically, then no memory should be detected. Most of the memory is not installed properly. Maybe the memory is damaged. If it is a Long sound, two short sounds, it should be that the graphics card is not plugged in, or the graphics card is broken, the need to replace the graphics card; when the system is running normally, the high frequency alarm sound is announced, then the CPU should be overheated, and the CPU fan heat is not good enough to replace the CPU fan. The operating environment temperature of the host is too high. The ventilation conditions are not good. It may be that the CPU alarm temperature setting in the BIOS of the motherboard is too low, and the demand is adjusted in time.

Question 2: When the host launches into the operating system, the supervisor becomes 16 colors and the resolution becomes 640*480 (the original graphics card and video capture card have been driven)

This is because a video capture card is damaged. The video capture card and the graphics card have conflicted. It is necessary to replace the corresponding video capture card and drive the graphics card from the beginning.

Question 3: Keyboard and mouse can not be used, how to distinguish and deal with?

If the keyboard and mouse can not be used at the same time, it is likely that the keyboard lock (KB-LK) is turned on. Check if the keyboard lock (KB-LK) light is on. If it is bright, it indicates that the keyboard has been determined. Turn it off. If only one of the keyboard and mouse can't be used, it is necessary to check whether the contact is outstanding. If it can't be used, it may damage the keyboard or mouse or the motherboard interface. Replace it with a good keyboard and mouse to find the problem.

Question 4: When entering the system, the system suddenly becomes very slow. The time of running the software may be very slow when I open my computer. How to distinguish and deal with it?

If you can enter the system normally, it is very slow, first of all to recover the system (select microsoft windows and enter when the system starts, then enter d:, then enter, then enter cd setup, enter, and then enter hf carriage return system I can recover.) If the recovery is still very slow, it should be a hardware problem. It is very likely that the hard disk is broken. It is necessary to find the damaged hard disk and replace it in time. It is also possible to add a hard disk. The power of the power supply is not good, and the power of the corresponding power can be replaced according to the situation.

Question 5: The host cannot be opened. What should I do?

After the primary cleaning display is not damaged, it is determined whether the power supply is normal, that is, whether the power light is on. If the power is normal, then the host is informed whether there is a announcement tone, and there is a looping sound that announces a long "beep" or a long sound, and two short sounds indicate Memory or graphics card does not work properly, please refer to question 1 processing; if there is no prompt tone, then it should be a problem in the power supply, motherboard or CPU (less probability of problem), should adopt the replacement sweep method (that is, replace the component with the recognition of normal Trouble with the parts in question, check them one by one. Identify the problem parts and replace them. In the meantime, the operating frequency of the CPU is not the default operating frequency of the CPU at that time. It is required to enter the BIOS to adjust the CPU frequency to the operating frequency at that time.

Question 6: When the software is launched, only the Xunhui logo is displayed on the screen, and there are no xunhui six letters at the bottom.

This is the wrong type of video capture card selected when the software is launched. Just adjust the driver of the card to display it normally. (Double-click the XHDVR-2004.INI file in the WINNT directory of the C drive, AutoSelect=1 Change the 1 to 0 to select the card from the beginning when the software is open. Perhaps the video capture card driver is not installed correctly. You need to install the corresponding driver and restart the host.

Question 7: When the software is launched or used, the channel with a picture is all black, and the time when the video signal is not connected is also all black (no five words without video signal). Hengyi card presents this problem more; perhaps in The colorful picture signals are monitored for right and wrong without adjusting the channel supervision parameters.

This is a damage to the video capture card, and it can be handled by replacing the corresponding video capture card.

Question 8: If you enter the software and encounter a flower screen,

It may be that the software is not properly exited, and the host can be moved from the hair; if the phenomenon is still moving from the hair, then it should be a problem with the graphics card. The graphics card should be replaced in time.

Question 9: There are a few minor issues to be aware of when setting up the timetable.

When setting up multiple recordings with different recording methods, it is necessary to pay attention to the fact that the software is recording in a 24-hour manner, so it is necessary to start the timetable less than the ending time when setting the timetable. If you cross the 24 point setting, you need to set it in two stages (such as 18.00.00 to 23.59.59, then 0.00.00 to 7.59.59). Mobile alarm video and alarm alarm video demand setting for arming (including manual arming and timetable defense), continuous recording is not required.

Question 10: When the recording method is set. However, the video cannot be recorded normally at a certain time. How to remove and process it?

If all channels can't be recorded (in the channel recording control, all channels are not in the yellow light condition.) Perhaps it is a video condition, but can not generate video files in the hard disk, then it should be a hard disk grouping error, you need to take the hard disk from scratch Grouping, and moving the software from the hair again, if the problem is still not processed, all channels are still blue lights, the time-sharing video files into the operating system can not be deleted, then the permissions of the hard disk should be changed, the need to adjust the permissions of the hard disk come back.

If it is an alarm video, one or more channels can not be alarmed. First, let's see if the recording method is set correctly. If the setting is correct, see if the detection area of the channel has been changed. If the correction is corrected, the channel must be corrected. The detection area is then moved from the hair software.

Question 11: When applied to the PTZ device, it cannot be controlled normally, how to distinguish and process it.

First look at the PTZ protocol, address code and baud rate are the same as the clarification requirements, if all are set, but the time of the control, the PTZ can not stop scrolling (normally, click it, it will scroll a little.) It should be that there is a problem with the device, and it is necessary to replace the PTZ device in time. When multiple PTZs are used, they cannot be controlled normally. Then, if the module (232 to 485) can be driven,

Question 12: When using the network, you can't monitor it. What should I do?

The first thing to understand is to use the network to monitor the satisfaction of several conditions, whether the network settings are set up, and whether the network is dredged? Is the 21 ports required for Internet access software through the router mapped to the host? Is there a fixed IP or domain name? If it is a LAN monitoring, then just make sure that it is set up, make sure that the network is unblocked (if the network is not clear, check the line) and the host is open to monitor. If it is a WAN monitoring, in addition to the network needs to set up, look at the host can access the Internet? False as above. See if the gateway and DNS settings are correct (where the gateway and DNS should be the router's IP)? Then see if the router can map the port to the monitoring host? A fixed IP or domain name is essential during this period. Only a few conditions fit together, and monitoring is no problem.

Question 13: Machine repeats active restart

This phenomenon is caused by some abnormal operation of the user, the cumulative effect causes the Windows system to crash, and the monitoring host has the function of crashing maintenance, that is, the Windows system is moved from the hair; in addition, the ventilation condition of the machine is not good enough to cause the chassis or CPU fan to be damaged and cause heat dissipation. Insufficient, causing the monitoring host to crash. Handling claims: Uninstall the software, then monitor the software from the scratch device; improve ventilation and replace the damaged fan.

Question 14: The software is inoperable

When logging in, the corresponding username and password were not entered; perhaps the Exit Login button was pressed. Please click the login button from the beginning, enter the corresponding username and password and log in.

Question 15: After launching the channel screen is a large picture

It is clarified that the system does not detect the existence of audio and video compression cards. It may be that there is no audio and video compression card or correct device driver on your machine. In addition, some IPC motherboards have poor compatibility with compression cards. This phenomenon is presented. Deal with claims: Please remove these possibilities.

Question 16: The number of channels is normal, but each channel shows magenta

Please adjust the color of the desktop display feature to 32-bit color.

Question 17: Software launches immediate statement fault

The probability of this fault being presented is extremely low and will not be presented on a properly managed host. Generally, the reasons for this problem are as follows: 1) The user's host is often powered off; 2) The software is run on a machine that is extremely unstable on hardware. Handling proposition: View the host equipment and move the software from the hair.

Question 18: Video recording of large scale files

The system faithfully records the video and audio signals generated by the board, and uses the compression algorithm of the Xiu Xiu to ensure that no critical picture is lost, ensuring the real-time performance of the video file during playback. The user can calculate the number of frames for the video file in question through the dedicated player of the system. In general, the system's default file size is normal within 120M/hour. If the listed conditions are not within these, it can be regarded as abnormal. You can start from the following aspects: 1. Investigate the corresponding channel preview picture, the picture should be soft, clear and flare-free, and not blind. If the glare of the eye is highlighted or there is a uniform snowflake flare on the picture; this clarifies that the original video signal is too noisy, please consider adjusting or replacing the camera; 2. The video quality is set too high and the movement is too intense. The video quality can be lowered as appropriate.

Question 19: There is a mosaic when the video file is played back.

Whether the host is causing serious resources for other reasons. For example, the host is currently performing multi-channel playback operations beyond the system. Once the host resources are exhausted and the recorded data cannot be decoded properly, mosaic may occur.

Question 20: The web side preview has an animation

The network communication bandwidth is not good. At this moment, the recording quality of the host side can be appropriately lowered.
