If your CCTV footage has gone missing — deleted, overwritten, or the DVR/NVR hard disk suddenly stopped playing back — the first instinct is panic, especially if the footage was needed for a security incident or an insurance claim. The good news: in most cases, that video is still recoverable if you act quickly.
Why CCTV footage disappears
CCTV systems in Kolkata homes and businesses usually lose footage for one of these reasons:
- The DVR/NVR was set to overwrite old footage automatically once storage filled up
- The hard disk inside the DVR developed bad sectors or stopped spinning
- Power cuts or surges corrupted the file system mid-recording
- Someone accidentally formatted the drive or deleted a specific time range
- The recorder’s proprietary file format got corrupted, even though the drive itself is fine
What to do the moment you notice footage is missing
Every minute the DVR keeps running, it risks overwriting the very footage you’re trying to save. Power down the recorder as soon as you realize footage is gone, and avoid the temptation to “try a few things” in the DVR’s own menu — reformatting or running disk checks from the DVR interface is one of the most common ways footage becomes unrecoverable.
Instead, remove the hard disk (or have a technician do it) and have it imaged before any recovery attempt. CCTV recovery is different from ordinary file recovery — DVR/NVR systems store video in proprietary container formats, so it usually needs specialist software that understands your recorder’s brand and firmware.
Logical vs physical CCTV recovery
Most CCTV recovery jobs fall into two categories. Logical failures — accidental deletion, formatting, or file system corruption — are usually resolved faster and at lower cost, since the disk itself is healthy. Physical failures — clicking noises, the drive not spinning up, or damage from a power surge — need a controlled lab environment, since opening the drive incorrectly can destroy the platters and the footage permanently.
