The crucial role of NTP time servers in the monitoring system

An NTP time server is a standard time server with the function of time correction. In the market, due to its standard protocol NTP conforming to most time correction protocols including computers, cameras, monitoring, industrial computers, etc., it occupies a considerable proportion in the current time synchronization market.

For the use of NTP time servers, first, it is necessary to check the functions of the device parameters, confirm the installation configuration and cable connection method based on its function parameters, and clarify the operation steps. Taking the time source as the first functional check point, where is the time reference source of the NTP time server? There are three ways: satellite time, superior time reference, and manual time setting.

For the three connection methods of the time reference source mentioned for the NTP time server, first, let's talk about manual time setting. Generally, it refers to sending instructions through the computer serial port or modifying the time through other methods. It can connect to the corresponding setting interface according to the function of the equipment and operate according to the instructions. The superior time reference generally refers to a main clock device or superior time source device in the synchronous time system. The NTP server can obtain the standard time source signal such as PTP through receiving the timing signal from the superior device, and configure the relevant link to obtain the standard time source signal according to the cable connection method.

Here, we focus on the use of NTP time servers for satellite time sources. For this type of timing service, there is usually a problem of satellite antenna installation. During the long-term use of the NTP server, mushroom head antennas are often used.

The NTP time server is a standard NTP protocol, meeting the time synchronization problems of NTP protocol devices and subsets of protocols, supporting all security protocols, encryption protection, firewall and other functional requirements in the NTP protocol. All devices are factory-set, meeting users' quick and portable use, and the system functions have been set. After the user gets the equipment, they only need to modify the IP address and gateway, click save and apply, and do not need to make too many modifications for other items.

When the NTP time server synchronizes with other devices, it only needs to obtain the IP address of the NTP time server in the Internet time zone or time setting area to achieve time synchronization with the NTP time server.
