DVR Time Difference Calculator – Fix CCTV Playback Time Issues Easily
When reviewing CCTV footage, one of the most common problems technicians and security personnel face is time mismatch between the DVR/NVR system and the actual time. Even a small difference can make it difficult to find the correct recording during investigations or playback.
To solve this, the DVR Time Difference Calculator is a handy tool that helps you quickly adjust and map the DVR time with real-world time.
🔍 Why Time Mismatch Happens in CCTV DVRs/NVRs?
CCTV systems often run continuously for months or even years. Over time, due to:
- Power outages
- System reboots
- Incorrect time zone or daylight saving settings
- DVR internal clock drift
…the time shown on the DVR/NVR may not match the actual time. For example, your DVR might show 10:00 AM when the real time is 10:30 AM.
⚡ How the DVR Time Difference Calculator Helps
This calculator allows you to:
- Enter the current DVR/NVR time (the time shown on your device).
- Enter the actual current time (your real local time).
- (Optional) Enter the required playback time – the real event time you want to check.
The tool instantly calculates the time difference and tells you the exact DVR time you need to open to view the correct recording.
📝 Example
- DVR shows: 10:00 AM
- Actual time: 10:30 AM
- Required playback: Yesterday 3:00 PM (Actual time)
👉 The calculator will inform you that the DVR is 30 minutes behind.
So, to check the footage for 3:00 PM actual time, you must open 2:30 PM on the DVR.
