How to Change the Time on a Surveillance Video Recorder (NVR/DVR)307

Changing the time on a surveillance video recorder (NVR/DVR) is a crucial task to ensure accurate timestamps on recorded footage. Incorrect timestamps can lead to difficulties in identifying events and reviewing video evidence. This tutorial will provide a comprehensive guide on how to change the time on NVR/DVRs with step-by-step instructions.

Step 1: Access the NVR/DVR Interface

The first step is to access the NVR/DVR interface. This can be done in two ways:
Local Access: Connect a monitor and keyboard directly to the NVR/DVR.
Remote Access: Use a web browser or mobile app to access the NVR/DVR over the network.

Step 2: Find the Time Settings Menu

Once you have accessed the NVR/DVR interface, locate the time settings menu. The menu location may vary depending on the NVR/DVR model. Common menu paths include:
System Settings > Time Settings
Configuration > System > Time
Main Menu > Settings > Time

Step 3: Adjust the Time and Date

In the time settings menu, you will find options to adjust the time and date. Use the provided fields to input the correct time and date. Ensure that you select the correct time zone to align with the location where the NVR/DVR is installed.

Step 4: Save the Changes

After adjusting the time and date, click on the "Save" or "Apply" button to apply the changes. The NVR/DVR will now display the updated time on its interface and apply the new timestamps to recorded footage.

Additional Tips:
Synchronize with NTP Server: To ensure accurate timekeeping, consider synchronizing the NVR/DVR with an NTP (Network Time Protocol) server. This will ensure that the NVR/DVR automatically adjusts its time based on a reliable time source.
Use Daylight Saving Time: If daylight saving time is observed in your area, remember to adjust the NVR/DVR time accordingly. Check the menu options to enable or disable daylight saving time.
Regular Time Checks: Periodically check the time settings to ensure they remain accurate. Inaccuracies can occur due to power outages or other technical issues.

Troubleshooting Time Issues:
Incorrect Timestamps: If the recorded footage shows incorrect timestamps, double-check the time settings and ensure they are correct. Verify the time zone and synchronize with an NTP server if necessary.
Time Jumps: If the NVR/DVR time jumps or skips forward or backward, check the system logs for any error messages. It could indicate an issue with the NVR/DVR's internal clock or a problem with the power supply.

Conclusion:

Changing the time on a surveillance video recorder (NVR/DVR) is a straightforward procedure that can be easily accomplished by following the steps outlined in this tutorial. By ensuring accurate timestamps, you can effectively manage recorded footage, identify events, and review evidence when necessary. Regular time checks and synchronization with an NTP server will further enhance the accuracy and reliability of your surveillance system.
