(5) The mall is monitored during the day, and there is a depression and alarm video at night. 5. Frequently Asked Questions (1) If there is a case where the installation does not record? The video is installed after the digital video recorder program will join the mysql2000log library, and it cannot be recorded. (2) When you start the digital video, you will exit it for a while. Starting a digital video machine will immediately exit because the four DATA partitions are too small, and if you want to reach the status, you should minimize each DATA partition 500m. (3) What is the mechanism of the disk full? If there is only 1G left in the storage space of the disk, crontab will automatically run to implement a periodic customization database and DATA partition. If the user wants to clear the data at any time, use the MTV-DM command. (4) How is the phenomenon in which the system instruction reaction is slower during installation and debugging? The system overhead is very large when the digital video system is running. The front desk will take some time process to switch, first look at the system process. Or check it with TOP, which process takes more system resources. Then kill the process of larger resource-consuming system resources with KILLALL -9. (5) Why do you have a long run program that will display the display screen of the blank screen point mouse button? Enter the Advanced Power Management of the BIOS to turn off the hard disk display when boot startup. 6. Technical Support If you have any questions when you use our products, please contact us.
