Troubleshooting Hikvision DVR/NVR Time Setting Issues: A Comprehensive Guide72

Hikvision digital video recorders (DVRs) and network video recorders (NVRs) are ubiquitous in the security industry, known for their robust features and relatively user-friendly interface. However, even with these strengths, users occasionally encounter difficulties setting the correct time and date on their devices. This can severely impact the usability of the system, making footage difficult to search and analyze chronologically. This article will delve into the common causes of time-setting problems with Hikvision devices and provide comprehensive troubleshooting steps to rectify them.

Common Causes of Time Setting Failures:

Several factors can contribute to the failure of setting the correct time on a Hikvision DVR/NVR. These can broadly be categorized as:

1. Network Time Protocol (NTP) Issues: Most Hikvision devices utilize NTP to automatically synchronize their clocks with a time server on the internet. If the device cannot access the internet, or the NTP server is unavailable or unreachable, the time setting will fail. This could be due to:
Incorrect network configuration: A faulty IP address, subnet mask, gateway, or DNS server settings can prevent the device from connecting to the internet and accessing NTP servers.
Network connectivity problems: Issues with the router, modem, or internet service provider (ISP) can disrupt the network connection, preventing NTP synchronization.
Firewall restrictions: Firewalls, either on the DVR/NVR itself or on the network, might be blocking the necessary ports used by NTP (typically UDP port 123).
NTP server issues: The selected NTP server might be down or experiencing connectivity problems.

2. Incorrect Time Zone Settings: Incorrectly configured time zone settings can lead to a significant time discrepancy. This is particularly important for devices deployed in locations with daylight saving time (DST).

3. Hardware or Software Glitches: In rare instances, hardware malfunctions (e.g., a failing hard drive or corrupted firmware) or software bugs can prevent the device from correctly storing or displaying the time.

4. Incorrect Date and Time Input: A simple yet common mistake is entering the incorrect date and time manually. Double-check all inputs to ensure accuracy.

5. Power Issues: Frequent power outages or power surges can disrupt the device's internal clock, resulting in incorrect time display.

Troubleshooting Steps:

To resolve time-setting problems, follow these steps systematically:

1. Verify Network Connectivity:
Check the network cable connection to ensure it's securely plugged into both the DVR/NVR and the network switch or router.
Check the DVR/NVR's network settings (IP address, subnet mask, gateway, DNS server) for accuracy. Consult your network administrator if unsure.
Test the internet connection on the DVR/NVR using a ping test to a known website or server.

2. Configure NTP Settings:
Access the DVR/NVR's configuration menu through its web interface or client software.
Locate the network settings and find the NTP server settings. Ensure that NTP is enabled and that the correct NTP server address is used (e.g., , ). Try different servers if one fails.
Restart the DVR/NVR to apply the changes.

3. Check Time Zone Settings:
Locate the time zone settings in the DVR/NVR's configuration menu.
Select the correct time zone for the device's location.
Ensure the DST settings are correct, especially if the location observes daylight saving time.

4. Manually Set the Time and Date:
If NTP synchronization fails, manually set the date and time using the device's configuration menu. Ensure accuracy.
Observe the time for a period to verify if it remains consistent.

5. Check for Hardware and Software Issues:
If the problem persists, consider the possibility of hardware or software issues. Check the hard drive's health. Consider upgrading the firmware to the latest version from Hikvision's official website.
Contact Hikvision support or a qualified technician for further assistance.

6. Review Firewall Settings:
Examine your network firewall settings to ensure that UDP port 123 is allowed for outgoing connections from the DVR/NVR.

By systematically following these troubleshooting steps, you should be able to resolve most time-setting issues with your Hikvision DVR/NVR. However, if the problem persists despite these efforts, seeking professional assistance from Hikvision support or a qualified security technician is recommended.
