Surveillance camera failure solution

1. What is the reason for the jitter in the display screen?

This situation is generally caused by the display refresh rate setting is too low, enter the "display properties" click "settings", select "advanced", then select "monitor", adjust the new frequency to 75HZ, after confirming to exit, it can be resolved This problem.

2. Why does a screen saver or a black screen appear on the monitor after powering on for a period of time?

This situation is caused by not canceling the screen saver or improper power management settings. The solution is to exit from the monitoring system, click the right mouse button on the interface, select "Properties", select the screen saver in the tab that appears, and select (none) to disable the screen saver. Then click the settings button in the lower right corner, select "Always On" in the power usage plan, the system waits to select "Never", turn off the monitor and select "Never", select "Never" in the "Turn off hard disk", and finally click Just "OK".

3. The digital hard disk video recorder's image display only has images without operation buttons or the screen is not full of the entire screen.

Under normal circumstances, the display resolution setting does not meet the requirements. Set the desktop resolution to 1024*768 and change the small font to large font.

4. How should the hard disk recording host be divided into zones?

System main hard disk:

1) Create a primary partition C: (2 to 3GB) (operating system + application software.)

2) Create an extended partition (100% of the remaining hard disk)

3) Create logical partition D under the extended partition: (usually 4GB is allocated, mainly stored in application backup and part of video data)

4) Create logical partition E under the extended partition: (remaining hard disk space) (recording data)

5. Why does a screen saver or a black screen appear on the monitor after the monitor is turned on for a period of time?

After exiting to the operating system interface, click the right mouse button on the interface, select properties, select the screen saver in the tab that appears, and select (none) to disable the screen saver. Then click the settings button in the lower right corner, select "Always On" in the power usage plan, the system waits to select "Never", turn off the monitor and select "Never", turn off the hard disk and select "Never" and then confirm.

6. Why is there no display after booting?

Please make sure that the chassis and monitor are properly connected, and the power is connected and turned on. The body may loosen the internal board components during transportation and moving. It is better to open the case before starting the machine and confirm that the components are connected tightly and correctly before powering on. If the motherboard self-test is abnormal when the power is on (the normal performance is that the keyboard indicator LED flashes once, the host buzzer beeps), please turn off the power, check whether the CPU board and graphics card are fully inserted, and the board can be removed Plug it back in. If the CPU fan does not rotate after pressing the power switch and the panel power indicator does not light up, please check whether the power supply is connected correctly.

7. What kind of operating system can the hard disk video card work under?

The hard disk video card can be used above Windows/2000 and supports PNP function.

8. Why does the system crash? How to recover?

When the improper setting of windows or other software failures cause the system to work abnormally, the system will crash. The following methods can be used to restore the system:

First: the method of windows registry repair system. For example, because the monitor is not turned on or the monitor connection is not normal when the system is started, the system cannot enter windows normally when the system is restarted. You can fix it according to the following steps.

Restart, hold down the F8 key during the startup process, select "Command Prompt only" in the startup mode selection menu, and type the following command line after startup: scanreg/restore select the date when the system was working normally to restore.

Second: When the problem cannot be solved by restoring the registry, the Ghost method can be used to restore the system, provided that the Ghost backup system has been used. The method of use is to boot (boot with hard disk or boot from WIN98 boot disk) to DOS state, run Ghost.exe, and follow the prompts to complete the system recovery

9. What should I do if there is no image display?

Reason 1: The graphics card is not compatible and can pass the Direct Draw test. If the test passes, it is not the reason.

Reason 2: The PCI interface is not in good contact, you can change to a PCI slot to test.

Reason 3: Whether the board is damaged, you can consider changing to another card for testing.

10. Installation instructions for audio and video card drivers.

You cannot install more video card drivers, only check the number of complete drivers in safe mode.

Example: You have 8 cards inserted on the motherboard, you can only install 8 drivers, you should check the number of audio and video card drivers in the "safe mode". If the video card driver exceeds the number of installed video cards, the system sometimes does not work properly.

Note: The four-channel real-time card is equivalent to 4 independent cards. 4 drivers need to be installed. The remaining audio and video cards have a driver for each card! If you find this phenomenon, you should put all video cards in the "safe mode" Delete all the drivers (including other duplicate devices in the system), and then restart the computer.

11. Why the computer cannot find the card?

Reason 1: The computer power is not an ATX power supply. Please use ATX power supply.

Reason 2: The PCI slot of the computer is damaged. Please try another slot.

Reason 3: The board card is damaged, please change the card to test.

12. What should I do if the video playback quality is poor?

For our hard disk video recorder under the'normal' compression quality, the video playback quality is relatively satisfactory. But sometimes it is found that the "mosaic" phenomenon is more serious, especially for moving images, the image becomes blurry, the main reason is that the brightness of your camera is too low (here do not try to change the brightness of the hard disk video recorder to compensate), you have to restart Adjust the brightness of the camera to compensate. This point should be paid special attention to in engineering construction.

13.What should I do if the real-time monitoring image is not clear?

You can select "normal camera" or "high-definition camera" in the system settings of the digital hard disk video recorder according to the model or definition of the configured camera; at the same time, you can also adjust the brightness, chroma, contrast and saturation of the video Value to achieve satisfactory results.

14. The monitoring is normal, but there is no sound during playback?

The reason is that "Recording allowed" is not set, just start the audio in the software settings.

15. Why does the setting not work?

All settings are effective at the beginning of half a minute after setting.

16.Why front-end control is not flexible?

The possible cause is that the decoder is not well connected with the pan/tilt, or the communication cable is too long. The general method of use is to install the decoder and pan/tilt nearby, that is, the decoder is generally installed near the pan/tilt.
