How do You Recover Clips From a Card Windows Cannot Open?
Windows sometimes calls a card unformatted and offers a format. Say no, since a format wipes the index that links a clip to its time. Recover CCTV footage with DVRXaminer when that offer appears.
RecoveryTools DVRXaminer takes an SD card as a source next to a recorder disk or a forensic image. A volume that Windows calls unformatted still resolves and the software names the vendor and the file system from the signature on the card.
DVRXaminer has a point and click window that lists every clip found on the card. Preview a clip, tick the ones you need and export them as MP4 or AVI. Camera name, channel and recording time stay with every file and the card is opened read only.
The trial scans, lists and previews without limits. Until you buy a license, you can save 25 clips per case and every saved clip stops at 60 seconds.

Which Habits Improve CCTV Footage Recovery?
Good habits protect your chance to recover CCTV footage without a second loss.
- Stop at once. Remove the card the moment you notice missing footage.
- Use a reader. Work from a reader, not from the camera.
- Save elsewhere. Send every recovered file to a different drive.
- Label the card. Note the camera, the site and the date before you store it.
Which Mistakes Destroy Clips on a Card?
Four errors make the clips impossible to get back later. People accept the Windows format offer or put the card back in the camera. Others save recovered files onto the same card. The last error is trusting a recovery after one quick look and not testing a clip.
My Verdict on CCTV Card Recovery
Open the card with a reader first and use Windows File Recovery for deleted files. That way you recover CCTV footage without writing to the card. Switch to DVRXaminer when Windows cannot read the card.
Stop recording before anything else.
