Troubleshooting DSM 7.2 DST (Daylight Saving Time) Settings for Cameras
Fixing DSM 7.2 DST problems with camera time sync
Problems with Daylight Saving Time in surveillance systems may seem small, but they can actually be very big. When DST settings are wrong in Synology DSM 7.2 environments, camera recordings often show the wrong time, events happen an hour early or late, and there are gaps in the timeline in Surveillance Station. These problems make it harder to do investigations, compliance audits, and keep operations running smoothly.
This guide goes over why DST problems happen in DSM 7.2, how they affect camera synchronization, and how to fix them one step at a time.
What causes DST problems in DSM 7.2
When the time settings on the NAS system, the camera’s internal time, and the Surveillance Station configuration are not all the same, DST problems usually happen. The new time handling and security controls in DSM 7.2 made things more accurate, but they also revealed problems that had gone unnoticed before.
Some common reasons are wrong regional time zones, cameras that use manual time instead of NTP, or older camera firmware that doesn’t fully support modern DST rules. Even a tiny difference can make recordings go out of sync.
How problems with DST sync affect camera recordings
When DST is set up wrong, recordings may seem to be off by exactly one hour. Motion events might not match up with what really happened, exported footage might have wrong timestamps, and playback timelines might show missing parts.
These mistakes can make businesses that rely on video evidence less trusting of surveillance data. Investigations, incident correlation, and following the law all depend on having accurate timestamps.
Step 1: Check the time and time zone in DSM 7.2
First, look at the NAS system time settings. To open the regional and time settings in DSM 7.2, go to the Control Panel. If your area observes it, make sure the right geographic time zone is chosen and that DST is turned on.
You should turn on automatic time synchronization with a reliable NTP server. You should avoid manual time settings unless you need them for isolated networks because they often cause drift.
Step 2: Check the time handling of the surveillance station
Next, look over how time is handled in Surveillance Station. Surveillance Station gets its system time from DSM, but if the camera settings aren’t set up right, they can change how it works.
Make sure that the camera time can be synced with the NAS. This makes sure that all of the cameras that are connected use the same DST logic as the system instead of their own clocks.
Step 3: Check the firmware and time mode of the camera
Most cameras come with manual time or vendor-specific DST rules by default. Check the settings for each camera and make sure that time synchronization is set to NTP or NAS-controlled time.
One common reason for DST problems is old camera firmware. Updating the firmware makes sure that the camera works with DSM 7.2 and follows the latest DST rules. This step is very important for older ONVIF cameras.
Step 4: Make sure the camera and NAS time sources are in sync
Cameras should only use a different NTP server than the NAS if they have to. If the time sources don’t match, the time can slowly drift or the DST can be off.
If you use the NAS as the main time source, all of your recordings will have the same timestamps. This is especially important when using more than one camera or site.
Step 5: After making changes to DST, restart services
After changing the time settings, restart the Surveillance Station services. This makes the system re-index timelines and use the right timestamps.
Sometimes, especially after seasonal DST changes, a full NAS reboot may be needed. This step makes sure that all background services use the new time settings correctly.
Best Ways to Make Sure Your Camera Time Is Correct on Synology DSM 7.2
Synology DSM 7.2 makes the system safer and more stable, but you need to be good at managing your time. Synology suggests that you sync your time in one place, keep your firmware up to date, and don’t make manual changes at the camera level. Using DSM as the only source of truth for time makes sure that the timelines in Surveillance Station stay correct during DST changes and system upgrades.
How to Stop Future DST Sync Problems
To avoid problems that keep coming up, make sure to check your cameras regularly before DST changes, keep the firmware up to date, and write down the standards for time configuration. Being consistent is important. When all of the devices use the same time source and rules, changes to DST go smoothly instead of causing problems.
