How to Set Up Network Time on Your Surveillance System175

Network Time Protocol (NTP) is crucial for a reliable and accurate surveillance system. Without properly configured NTP, your recorded footage may be difficult to correlate with events, and timestamps will be inaccurate, potentially impacting investigations or legal proceedings. This can lead to significant issues, especially when dealing with security incidents requiring precise timing. This article will guide you through setting up network time on various surveillance systems, covering different scenarios and troubleshooting common problems.

The process of setting up network time varies depending on the type of surveillance system you have. Generally, you'll be configuring this within the system's Network or Time settings menu, accessible through a web interface or dedicated software. Let's break down the process into common steps and considerations:

Identifying Your Surveillance System and Access Method

Before beginning, you need to identify your surveillance system's make and model. This is critical because the specific steps will differ across manufacturers and system versions. Common brands include Hikvision, Dahua, Uniview, and many others, each with its own user interface and configuration methods. You'll typically access the settings through a web browser, using the IP address of your DVR, NVR, or video management system (VMS). Consult your system's manual for the specific IP address and login credentials.

Accessing the Network Settings Menu

Once you've logged into your surveillance system's interface, locate the Network settings menu. This might be labeled differently, such as "Network Configuration," "System Settings," or "Network Parameters." The exact location and terminology depend on your system's manufacturer and version. Within the network settings, look for an option related to time synchronization or NTP settings.

Configuring NTP Server

The core of setting up network time involves configuring your system to use a reliable NTP server. NTP servers are time servers that provide highly accurate time information. You'll need to input the IP address or domain name of an NTP server. Popular and reliable NTP servers include:


(This is a pool of servers, automatically selecting the best one for your location)
, , etc. (Specific servers from the pool, allowing for redundancy)

You might be able to input multiple servers for redundancy. If one server is unavailable, the system will automatically fall back to another. Some systems offer options to specify a primary and secondary server.

Setting Time Zone

After specifying the NTP server(s), you'll need to configure the time zone. Ensure the time zone setting accurately reflects your geographical location. Incorrect time zone settings will lead to inaccurate timestamps on your recordings. The system should provide a list of time zones to select from.

Testing the Network Time Synchronization

Once you've configured the NTP server and time zone, save your settings and test the network time synchronization. Check the system's current time displayed on the interface. It should accurately reflect the current time based on the selected NTP server. If the time is incorrect, review your settings to ensure they are correctly configured.

Troubleshooting Common Problems

If you're encountering problems setting up network time, consider the following troubleshooting steps:
Network Connectivity: Ensure your surveillance system has a stable network connection. A faulty network cable or network issues can prevent NTP synchronization.
Firewall: Check your firewall settings to ensure that the system is allowed to communicate with the NTP server(s) on UDP port 123. You might need to add an exception for the NTP server's IP address or domain name.
DNS Resolution: If you're using a domain name for the NTP server, ensure your system's DNS settings are configured correctly. A DNS resolution failure can prevent the system from locating the NTP server.
NTP Server Availability: The NTP server itself may be temporarily unavailable. Try using a different NTP server from the list provided.
System Time Manual Override: Some systems may have an option to manually set the time, which should be avoided unless absolutely necessary. Relying on NTP for time synchronization is the most reliable approach.

Advanced Configurations

Some advanced surveillance systems allow for more granular control over NTP settings, such as specifying the update interval (how frequently the system synchronizes its time), or selecting a specific stratum (a measure of the server's accuracy). These options are typically found in the advanced settings and require a good understanding of NTP before modification.

Properly setting up network time is essential for maintaining the integrity and reliability of your surveillance system. By following these steps and troubleshooting common issues, you can ensure accurate timestamps on your recordings, enhancing their usefulness in investigations and security analysis.
