CCTV Time Difference

CCTV TIME DIFFERENCE Determine, document and report CCTV clock discrepancies quickly and accurately. CCTV Time Difference is a professional tool for investigators, security professionals, CCTV technicians and others who need to establish the exact difference between a CCTV system timestamp and the correct reference time. Create a case, capture the displayed CCTV timestamp using the iPhone camera, let OCR read the time, and compare it with the calibrated reference time. The app instantly calculates the exact offset and clearly shows whether the CCTV system clock is ahead of or behind the correct time. Your examinations can be saved as individual cases, allowing you to return to previous work and keep multiple CCTV time examinations organized. KEY FEATURES • Case Management – Create new cases or return to previously saved examinations • Automatic OCR – Capture a still reference image of the timestamp displayed on a CCTV monitor and let the app read the date and time automatically • Calibrated Reference Time – Compare the CCTV timestamp against an accurate reference time • Instant Time Difference – Automatically calculate the exact difference between the CCTV clock and the reference time • Ahead or Behind – Immediately see whether the CCTV system clock is running fast or slow • Manual Time Entry – Enter or correct the displayed CCTV time manually whenever required • Multiple Examinations per Case – Keep relevant time examinations together within the same case • Professional PDF Reports – Generate detailed reports documenting the examination and calculated time difference • Save or Share Reports – Keep the completed PDF report or send it using the standard iOS sharing options • Dark & Light Mode – Choose the appearance that works best for you WHY CCTV TIME DIFFERENCE MATTERS CCTV clocks are not always synchronized with the correct time. A recording system may be seconds, minutes or even hours out of sync. When CCTV footage is compared with witness statements, access-control records, communications, transactions or other time-based information, knowing the actual clock difference can be essential. CCTV Time Difference provides a structured way to establish, document and report that difference. From a single timestamp check to multiple examinations within a case, the app keeps the process simple, consistent and easy to document. 14-DAY FREE TRIAL Try CCTV Time Difference with full access for 14 days. After the trial period, continue using the app with a single one-time purchase that unlocks the full app permanently. No subscription. No recurring payments. Once purchased, your full access does not expire. CAMERA AND OCR USE The iPhone camera is used only to capture a still reference image of displayed information, such as the date and time shown on a CCTV monitor or system interface. The still image is used as input for OCR recognition and as documentation of the time information examined by the user. The camera feature is not used to record surveillance footage or other CCTV video. CCTV Time Difference does not connect to CCTV cameras, DVRs or NVRs to retrieve recordings. The app does not download, copy, stream, extract or distribute CCTV video or audio. Images captured by the app are used as reference and documentation material within the user's CCTV time examination workflow and are not captured for publication, entertainment or redistribution of surveillance material. CCTV Time Difference is a focused calculation and documentation tool for CCTV timestamp examination. It is not a CCTV recording, surveillance monitoring, video acquisition or media distribution application.
