The role in practice
In a system with multiple cameras, one abnormal channel can only stand out when images are placed side by side or an export is made.
advice
Check Hikvision time synchronization
A consistent clock makes the timeline reliable and prevents discussion about the moment of an event.
What should be clear in advance
Compare date and time on the recorder, live view and app and check which time source is being used. Pay extra attention to an hour difference after summer or winter time.
Set without side effects
Correct the central source according to the system design and avoid manual loose adjustments that later diverge again. Document the chosen time zone.
Focused checking
Take a test recording and compare the timestamp with a reliable local time. Check after a time change whether the synchronization remains intact.
Frequently asked questions
Why do the camera and NVR sometimes have different times?
They can use different settings or time sources.
Is a few minutes difference important?
This may be relevant for incident investigation and the combination of images.
